Update on the Hatsan Jet II – It’s Pretty Wicked!

I wrote a series of posts about purchasing a .22 Hatsan Jet II right after I bought it in early January 2022. After shooting it for a month I have some feedback to share.

I’d guesstimate I have just over a 100 rounds through it. I’ve changed quite a few 7 round mags – that much I know for sure. The first thing I want to tell you is that the performance and reliability are surprising. It reinforces to me that Hatsan can turn out some great airguns.

The Shroud Is True

I was a little worried about how true the shroud would be relative to the center of the barrel’s bore. In my Gladius, it was not. With the Jet II, it is. The way you can tell is that pellets are landing all over the place because they hit the adapter or somewhere in the moderator and spin out of control. In other words, accuracy is horrible until you remove the moderator and/or the adapter. The DonnyFL 1/2-20 male to male adapter screwed right and then the Hugget Sniper to it and accuracy was great.

Accuracy

Speaking of accuracy – I was very happy. Once I dialed in the scope I had no problem shooting 1/2″ 7 round groups using 18.13 JSB Exact Jumbo Diabolo pellets at 12 yards from a bench. To be clear – just me resting my arm on the bench. I didn’t have a true rifle stand.

That is 7 rounds of .22 18.13gr JSB Exact Jumbo Heavy Diabolo pellets at s12 yards. Ignore the blatant flier – that was my fault, not the gun’s or the pellets. I was firing supported from a bench but the Jet II was not in a bench rest. I’ll do some accuracy testing one of these days.

Now, another form of accuracy is to tell you about squirrells. I have cleanly dispatched 8 over the last three weeks. Distances vary from 12-16 yards.

The Jet II really likes these pellets. I really like JSB in general for all of my pellet guns.

The Charging Handle

In my first review I voiced a concern about the polymer charging/cocking lever. So far, it has worked just fine – no signs of any loosening or bending.

The cocking handle is doing just fine.

Air Use

I purposefully bought the Jet II due to the larger air reservoir than the Jet I. I could shoot two mags with no noticeable change in trajectory in my 12 yard test range shooting 18.13 JSB Exact pellets.

My usual approach is to shoot a mag and then top of the Jet II from my air tank at the same time I reload the pellets in the magazine. I have a spare magazine ready to go so if I was in a rush for some reason I know I have a little bit of buffer just in case I need it – I’m using the gun for pests and not target shooting.

I had it filled pretty close to the 250 bar max. What you see is the amount of air left after 14 shots (two magazines). I have not tried shooting more than two mags after refilling.

Snipe Moderator

I’m using the Hugget Snipe moderator and it almost makes the Jet II backyard friendly. It’s far quieter with it of course – I just wish it was quieter yet and will experiment some more with different cans.

The Hugget Snipe does a very good job. I wish it was even more quiet but that’s not really a negative reflection on the Snipe.
With the Snipe, the overall length is approximately 30″. From an overall length perspective, it’s a great combination.

Summary

At this point I am still very happy with the Jet II for it’s intended pest control purposes. It’s definitely effective and amazing for the price when you stop and think about it.

Here’s the listing at Pyramyd Air and I always recommend you use their 10 for $10 test service:

Introducing the New Unique Hatsan Jet II: Post 3 – Mounting a Scope

In first post, I told you a little about the Jet I and II pistols and how I ordered a Jet II in .22 plus I shared some specifications and photos. In the last post I went over adding a moderator and in this post, I am going to show you how to add a scope. Because the Jet I and II are almost identical other than the twin air cylinders in the II, this post should help anyone wanting to add sound suppression to their Hatsan Jet pistol/carbine.

Okay, so you have two rail sections – one runs the length of the barrel and the second section is just behind the breach. Despite what you may read that the pistol is set for an 11mm dovetail, which is partly true, it is also set up for Picatinny rails. I noticed in my Hatsan Gladius that they did this interesting hybrid optics rail that supported both and they did it again with the Jet.

This means you have tons and tons of options. Now, I went with an inexpensive UTG 3-12×44 compact scope with a 30mm tube, adjustable objective, illuminated M-il-Dot reticle and rings. (This is their SCP3-UM312AOIEW scope). I don’t use UTG on firearms but I have no problem running them on airguns and have used a number of different models over the years. Honestly, you can run whatever you want as long as you can figure out how to mount it and clear the mag and the breach area. Click here to go to Amazon to see a number of different UTG scopes.

Now this next part is a bit of a work in process. Right now I am running a medium height 2″ offset scope mount like you would find on an AR. I think it is from Primary Arms but am not 100% sure. What I wanted to do was to keep the mount purely on the barrel to avoid any alignment issues between that section and the rear section. Even as far back as I can move the scope, I still have to choke up on the gun a bit to get the proper eye relief on the scope. I may either move to a 3″ offset mount or just go ahead and try seeing what I can do with two separate rings and see how the alignment goes. Another option might be a scope with longer eye relief … we’ll see how things go.

Let’s take a look…

You have all of the rail space on the barrel.
Plus a little bit more on the rear. I was worried about alignment over time and opted to just mount on the barrel but I am rethinking that and may try a pair of rings in the future,
My first test optic was a 1-6×24 Vortex Strike Eagle. For airgun work there is just not enough magnification bit it did confirm the rail was configured to properly hold a Picatinny rail mount.
The top dovetail is the small 11mm style. I don’t know if you can see the contour of the top and how it is beveled – that is for the larger Picatinny mounts. It’s unorthodox but if works. The end of the day this is a PCP (pre-charged pneumatic – meaning it has cylinders of compressed air) airgun and will have little to no recoil to deal with.
This is a one piece 30mm mount with a 2″ offset. My best guess is that I bought it from Primary Arms but I really am not sure because it was sitting lose on a shelf with no packaging. It’s about a medium height.
The mount just barely clears the magazine. The magazine sticks up about 0.392″ from the bottom of the rail just so you know and it is the highest thing you need to clear. The magazine slides in straight from the side and is held in place by friction fit so you don’t need to worry about lifting the mag out – it just needs to be able to slide in under the mount or the scope tube itself.

Boresighting the scope

Now this was a bit of an adventure. I like to use a laser boresighter but I couldn’t find any of the collets for stabilizing the stem so I wound up inserting and stabilizing it with one hand while adjusting the scope knobs. In the end, I was about 6″ down and 3″ right of the bullseye at 10 yards but it did get me close enough to actually shoot and dial in the scope.

So let’s wrap up this post

Instead of dealing with the 11mm dovetail, I am happily using the Picatinny rail. The combination of one piece 2″ offset mount and UTG compact scope are working for now. I just wish I could get the scope a tad further back or get a scope with longer eye relief. I may get a 3″ offset mount and give it a try as I really would like to mount the scope to the barrel’s rail.

So far so good. I hope this gives you some ideas.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Introducing the New Unique Hatsan Jet II: Post 2 – Adding A Moderator

In the last post, I told you a little about the Jet I and II pistols and how I ordered a Jet II in .22 plus I shared some specifications and photos. In this post, I am going to show you how to add a moderator. Because the Jet I and II are almost identical other than the twin air cylinders in the II, this post should help anyone wanting to add sound suppression to their Hatsan Jet pistol/carbine.

It comes with a threaded shroud that stabilizes and protects the barrel plus provides a 1/2″-20 threaded end. It does not come with any sound suppression out of the box. For those of you are familiar with sound suppression in airguns, they go by a number of names – moderators, air strippers, suppressors and sometimes silencers. Personally, I use the term moderator to make it very different from firearms and avoid confusion.

Next, airgun moderators are not regulated like firearm suppressors are plus the designers take great care for them to not work on firearms – the threading is different and the internals are made from plastics or fibers that will melt or blow apart if put on a firearm. The moderator market is competitive and different vendors have different designs with varying degrees of effectiveness,

In short, airgun suppressors are made for use only on airguns and they do serve real purposes – they make the gun backyard friendly to avoid worrying neighbors, they reduce the sound signature to not scare away whatever pest or game you are trying to shoot plus if you have a big bore airgun the reduced sound levels protect your ears.

Now, when t comes to a .22, there isn’t a very loud retort when the airgun fires but you definitely can hear it. By using a moderator, the airgun becomes very quiet. It’s not perfectly silent – that’s largely a myth just like firearms – but it sure does quiet them down.

Last comment – many airguns come with moderators built in such as the Hatsan Quiet Energy line plus many of the more expensive PCP airguns either come with a moderator built into the shroud or have a threaded barrel to allow one to be screwed on.

There are three moderator companies that I have had very good luck with and have no hesitation recommending – DonnyFL, Huggett Precision Products and EdGun. In today’s post, I’ll use a Huggett Snipe that I bought from Utah Airguns (who has quite a selection of brands and models) and a DonnyFL A21 adapter to mount it.

Let’s Get To It!

These holes that look like ports in the shroud are just for looks – the same way that having the serrations in a shroud are for looks. The shroud stabilizes and protects the barrel plus has threading for adding a moderator but that’s it. There is no integral moderator. You’ll need to add that but that’s ok and I’ll tell you why and how in another post.
Inside the muzzle end of the shroud are 1/2-20 threads for adding a moderator. So, if you get a 1/2-20 male to male fitting, you can add your favorite brand of moderator. I’ll cover more about this later.
This is the DonnyFL A21 adapter with the tread protector screwed on. Note, there are other male-to-male 1/2-20 adapters out there. I went with DonnyFL as they are a good business work with and their machining is always top notch.
This is the DonnyFL A21 adapter and it simply screws into the end of the shroud. I am happy to report that the barrel does appear to be properly centered. I was not so luck with my Gladius and could not mount an external adapter. For my Jet II though, it lines up great. Note, it comes with a threaded muzzle protector / thread protector that screws off. It’s very nicely made and finished by the way.
One nice feature is that both ends of the adapter have holes in them so you can insert something round, like my punch here, and snug down the adapter. Bear in mind that the threaded adapter is screwing into polymer. You just want to snug it down or else you are liable to strip out the shroud’s polymer threads. You do want to do this because when you screw the moderator on or off, you want the adapter to stay put and it will. Just don’t go crazy with the torque is my warning.
This is a Snipe made by Huggett Precision Products in the UK. It is threaded for 1/2 UNF which means Unified Fine which is also is written as 1/2-20 meaning 20 threads per inch.
The business end
This is the 1/2-20 threaded base.
The moderator is lightly screwed onto the DonnyFL adapter.
Again, it all lines up and shoots great.

So let’s wrap up this post

Okay – the combination of Hatsan Jet II, DonnyFL A21 adapter and Huggett Snipe moderator work really well. I bet you’re wondering about the scope and that will be the next post.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Air & C02 Rifles and Pistols

Introducing the New Unique Hatsan Jet II – A Versatile Compact PCP Airgun: Post 1 – Out of the Box

I first saw a photo of the forthcoming Hatsan Jet I and II airguns in November of 2022 and was very interested in them. As more info started coming out, I really focused on the Jet II as it has twin air tanks. You see, I like short airguns for handling pests so I needed something to authoritatively deal with ground squirrels, tree squirrels and the occasional rabbit.

I have an amazing FX Impact Compact Mk II in .25 but wanted something even smaller but with less over penetration. I used to include having less of a report but switched from a DonnyFL Emperor to one of the new EdGun Behemoth moderators with an additional module and wow is that thing quiet now but that is a story for another day.

So, back to the point – I wanted something even smaller than the Impact Compact with less energy but didn’t want to spend a fortune either – sure, I’d love a Leishy II, Layla or something similar but don’t have that kind of money. As the just-before-Christmas release date drew near, the pricing came out and the suggested pricing was very affordable at $289.99 for the Jet I and $339.99 for the Jet II plus vendors were planning to come in lower. Ok, I had some thinking to do and very quickly decided to order the Jet II in .22 from Pyramyd Air and added their 10 for 10 test to try and guard against getting a defective unit.,

Specifications

  • It’s a side lever operated repeater
  • Available in .177, .22 and .25 – I opted for the .22 model
  • Magazine capacity: .177 is 8 rounds, .22 is 7 rounds and .25 is 6 rounds – these are small magazines for a small airgun
  • Barrel length: 7.9″
  • Each air cylinder holds 40cc so the Jet II holds 80cc of air
  • Pressure is 250 bar (3,626 psi)
  • There is a built in pressure gauge
  • Power is not regulated (the more expensive airguns tend to have regulators that step the pressure down from the tank to a lower more o consistent level that is then sent to the pellet upon firing. Higher end air guns may even have two regulators. For the price point, the Jets do not have a regulator and you’ll be just fine though I will tell you this is why I bought the Jet II – I wanted a larger air volume and a slower corresponding drop in pressure compared to the Jet I.
  • The barrel has a shroud to protect and stabilize it but nothing more. There is no integral moderator/suppression in the shroud.
  • Hatsan reports the barrel is rifle and made in Germany but they don’t mention the manufacturer – not sure if it is made Walthar or just who and will update this if I find out
  • Split length 11mm dovetail and Picatinny rail – it runs over the entire barrel and for a short amount behind the breach. Note: This combination rail design was also on my Gladius and hasn’t been reported in the press for some reason. You do not need to be limited to just 11mm.
  • Has three flip up sights – one front and then two at the rear depending on whether you are shooting it as a pistol or a carbine
  • The stock can be easily installed or removed with a push button
  • It is adjustable for length with a rubber recoil pad and a vertically adjustable cheek piece
  • Overall length of just the pistol: 15″
  • Overall length with the stock collapsed is about 23-3/16″ and fully extended it is just over 24-3/4″.
  • If I use the back of the rear sight as a starting point, length of pull collapsed is about 9-5/8″ and fully extended it is about 11-9/16″.
  • 1.4 pounds without the stock and 3.4 pounds with the stock
  • Now the next stats are reported by Hatsan and I want to take a moment and recognize them for conservative reporting. Whereas some vendors inflate their numbers (meaning they exaggerate), Hatsan tends to be truthful and if anything their airguns perform better than they report:
  • Max Velocity – Lead Free Pellets – 810 FPS – .177; 700 FPS – .22; 600 FPS – .25 (depends on the type of pellet and other factors)
  • Max Velocity – Lead Pellets – 788 FPS – .177; 700 FPS – .22; 600 FPS – .25(depends on the type of pellet and other factors)
  • Max Muzzle Energy – 9.7 FPE – .177; 15.6 FPE – .22; 16.5 FPE – .25 (depends on the type of pellet and other factors)
  • Shots at Optimal Velocity – 48 – .177; 42 – .22; 30 – .25

Notice the muzzle energy reported in Foot Pounds of Energy (FPE). I want to use this to eliminate squirrels and the .177 with 9.7 FPE is on the lighter side. There are guys who hunt squirrels with .177 but I tend to think they are pushing heavy pellets faster and delivering more FPE. My first choice would have been .177 but given the numbers I decided to go with a .22 and the 15.6 FPE.

How much is enough FPE for squirrels starts arguments and chest thumping online one post cites 9 FPE for minimum energy and then you have folks swearing clean kills at 5 FPE with headshots. My point is that there are tons of claims out there. I know 15.6 FPE will do the job if I do mine in terms of accurate shot placement so that’s my rationale.

Opening The Box

On December 28th, the carbine arrived from Pyramyd Air and it did not disappoint.

The Jet II arrived in a flat box and inside was the pistol, the stock and in the box are two mags, a female quick connect fitting and some o-rings. Is this a pistol or a carbine? The answer is yes. I have found Hatsan’s designs to be novel and forward looking – this is no exception.
This is looking straight on at manometer (the pressure gauge). It looks like Pyramyd Arms did their 10 for $10 test but didn’t bother refilling the tank. So the gauge is in the top cylinder. The bottom cylinder has a cap on and under it is the male quick connect fitting for filling the airgun.
Inside the muzzle end of the shroud are 1/2-20 threads for adding a moderator. So, if you get a 1/2-20 male to male fitting, you can add your favorite brand of moderator. I’ll cover more about this later.
The quick connect foster fitting is protected by a black plastic cover. Note the 250 bar limit printed on the cylinder.
The cocking lever is polymer. I’d rather it were aluminum but let’s see how it holds up, Injection molded composites these days are amazing so this may do ok. Time will tell. Also, that optic rail also runs forward of the breach the whole length of the barrel and supports both 11mm and Picatinny. Most reviewers and listings have overlooked that. I will do a blog post showing a scope mounted with Picatinny rings directly.
These holes that look like ports in the shroud are just for looks – the same way that having the serrations in a shroud are for looks. The shroud stabilizes and protects the barrel plus has threading for adding a moderator but that’s it. There is no integral moderator. You’ll need to add that but that’s ok and I’ll tell you why and how in another post.

Now, let’s look at the stock

Let’s next turn our attention to the attachable stock that is very slick and can be easily attached or removed.

The stock is really interesting. The male plugs go into the female receptacles in the pistol. The knob on the lower left adjusts the height of the cheekpiece and the the square button just forward of the middle lower part of the stock moves a detent and allows you to make the stock longer or shorter.
The lower plug has a locking mechanism to keep it secured in the pistol.
The top plug has an O-ring installed. What this does is provide resistance/springiness for a firm lock-up. When you push the stock into the pistol the O-ring compresses to create a solid feeling connection.
This is looking at the female receptacles on the pistol that the stock’s plugs will go into.
That square button allows enables the stock to telescope in or out.
There are a total of six adjustments in the stock. Overall length with the stock collapsed is about 23-3/16″ and fully extended it is just over 24-3/4″. If I use the back of the rear sight as a starting point, length of pull collapsed is about 9-5/8″ and fully extended it is about 11-9/16″. There is a slight amount of play, or wiggle, in the lock up of the stock but it’s really not much and thus acceptable
It looks slick and goes to the shoulder very easily. The balance is good too. You can see the two magazines and bag of goodies that were in the accessory box.
I wear XL-sized gloves and my hand fits the grip but just barely. Oddly it’s my middle finger’s middle knuckle that feels the tight fit. I wish there was just a tad more room before the start of the trigger guard but I can live with it. I do want to point out one thing I really like – the safety flips up from the bottom of the trigger guard. I really like designs that put the safety where it can be readily turned off without moving your head or your hand to find the safety leverl. Big kudos to Hatsan for that. My Gladius had one at the front of the trigger guard and I could very easily feel it’s status or turn it off without moving my head.

So let’s wrap this first blog post

I will do more posts about adding a moderator and the optic. I’ve already done some test firing at targets and really like the little “carbine” – I think that’s what I’ll call it. So, if you are looking for something new and compact, check out the Jet I or Jet II in the caliber of your choice.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Review Of The .22 JSB Hades Pellets – Do They Really Work?

I have a Hatsan Gladius Long precharged pneumatic (PCP) air rifle in .22 caliber that I use to dispatch garden pests and have written a number of posts about it. It’s extremely effective because it has power, is accurate and relatively quiet. The one challenge I have with it is over penetration. It does have adjustable power settings but I find that I can’t go below the “3” setting (out of five) to have the range I need and enough power for a humane kill. The problem is that the domed JSB Diablo 18.13gr pellets I’ve used since the start shoot right through a squirrel if I am going for a heart shot vs. a headshot and really wanted to reduce this so I started reading on pellet types.

First off, I really like JSB pellets. They are made in Czechoslovakia and are really uniform. I shoot them in both my PCPs and have no complaints. I saw an advertisement for their new “Hades” series of pellets and started searching on what people were saying about them.

Basically the Hades are a form of hollow point that really need the power of a PCP to mushroom. The ones I bought at 15.89gr and have a very intriguing shape to the head.

A 15.89gr Hades is on the left and an 18.13gr JSB Jumbo Heavy Diablo is on the right. The Diablo has proven to be wonderfully accurate and my farthest shot has been about 50 yards with it.

My Real World Review

There are guys out there with chronographs, blocks ballistic gelatin and what not. I’m not one of those guys. However, I can tell you want I’ve noted after about 150 real world shots.

Most of my pest control happens within 60 feet – yes, feet. I set up a target at 30 feet and zeroed my scope. In firing groups, it seemed consistent enough.

Good enough for me.

Did I see anything different with garden pest control? Not really to be perfectly honest. I can tell you the exit wound was bigger than what the Diablos would leave and it was somewhere around half again the diameter of the pellet.

I still have over-penetration with the Hades and the need to be very careful is still true. Both tree and ground squirrels are small and soft. There’s simply not a lot of mass there to stop a pellet. If you have bigger pests, you might see a difference.

I did one close range headshot of a racoon at the rifle’s highest power setting and did not see a difference over what Diablos would do.

My Hades pellets are on the left. I bought two of the 200 round tins initially and backordered two of the 500 round tins that have since arrived. I have about 1200 rounds of the Hades left as the first tin is almost empty and then I will go back to my Diablos as I have 3-4 of the big 500 round tins.

Conclusion

For my use as described above, I did not see a big difference between the Hades and the Jumbo Diablos. The Hades seems to be a decent pellet as long as you have accurate shot placement. I bought a ton of Diablos way back when so I’ll use up my Hades and then go back to my supply of Diablos.

I hope this helps you out.

9/18/23 Update: I am now using Hades pellets in my .22 Leshiy 2 and I do think they make a difference when it comes to dispatching tree squirrels for pest control. It may be the Hatsan just didn’t push the pellet fast enough – I’m not sure. Amazon is carrying a number of calibers so click here if you’d like to see them.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

New Hatsan PCP AirGun Fill Probe Parts – O-rings and Caps

I have two Hatsan precharged pneumatic (PCP) airguns – a full size Gladius .22 long and a compact ATP2. I recently needed to replace the O-rings and started researching what was needed.

The O-Rings

Here’s a Hatsan probe and the brownish/tan O-rings are their OEM rings. The black rings are the Buna-N rubber rings that we are now selling.

My two Hatsan’s get pressurized up to 300 bar, which is 4,351 PSI. That’s quite a bit of pressure that the fill probe’s O-rings need to contain plus they need to be flexible enough to allow for insertion and a good seal. One last consideration is the need to withstand the silicone grease that is used to lubricate them (never use oil-based grease on a PCP or it may diesel under pressure).

The O-rings are wear items meaning they will wear out for a variety of reasons and you can tell because when you go to fill the airgun’s tank, you will hear air escaping plus you probably will not be able to get very much pressure to stay in the line. So when mine went out and I installed the spare set that came with the Gladius, I had to think about getting more spares. Hatsan was out of stock at the time so I decided to dig.

So, I started researching what O-rings would work best and sourced some that work great. They are 70A on the shore hardness scale and made from Buna-N rubber which will withstand the silicone grease.

In addition to fitting Hatsan PCP fill probes, they will also fit the Air Venturi Halestorm, Evanix, FX, Hammerli Pneuma, Kral, Lgun and Raider probes.

Click here for the product page on our website to see pricing and place an order.

Keeping the Probe Clean – Caps

While I was at it, I decided to tackle how to keep the probe clean. I’ve had my Hatsans and my Hill Mk4 air pump for a couple of years and have tried to keep bags on the probe to keep it clean. Those semi-rigid airlines flop everywhere and trying to keep dirt off the probe that is sticky with silicone grease is a challenge.

Here’s the uncovered probe begging to have dirt and debris stick to it.

So, after measuring stuff. I came up with two types of caps for people to choose from. The first is a yellow cap with a pull tab.

Here’s the yellow pull tab cap that extends just past the rear O-ring

Air & C02 Rifles and Pistols

Hatsan AT-P2 QE: Questions & Answers

As mentioned previously, I purchased a Hatsan AT-P2 QE pistol.  A few guys email med asking questions and I decided to post my answers here for others to read also:

How comfortable is it?  It looks like a kid’s toy.

I’m 5′ 8″ and find it very comfortable shoot.  I wanted a small profile PCP repeating airgun so I bought it wanting to hold it close to show a small profile.  I’m right handed and my left hand naturally goes to the front of handguard.  I think that is why they designed it with that angle.

I have the stock adjusted one click back out of five.  The cheek piece is adjustable but I found it did not need to be changed.  Again, it works fine for me.  I have no interest in trying to use it as a giant pistol.

How tight is the stock?

It wiggles just a tiny bit without a load but once I put it to my shoulder and place my cheek on the rest, it is solid.

Does it have two triggers?

No.  The front thing that looks like a trigger is the safety lever.  It’s actually very slick once you get used to it.  My Gladius has the same safety and trigger set up.  While it may look different, you can very easily turn it on, off or check the status.

The trigger is colored gold and the think safety lever is in front of it.

The trigger itself is Hatsan’s Quattro trigger and is user adjustable.  It has three screws for overall trigger travel, second state engagement and trigger pull weight.  Hatsan USA has a video on how to adjust the trigger – click here.

Does Hatsan make decent air guns?

Yes, they actually make very good airguns.  They are located in Turkey and don’t have the same brand recognition as Daisy, Crosman, Gamo, etc.  I posted factory tour video a while back that I found.

Why did I pick .22 caliber?

Well, I was worried that if I went with .177 that I would not have enough foot pounds of energy (FPE) to cleanly kill the pests I expected – squirrels, ground squirrels, and rabbits.  In talking with guys and reading, I decided to go with .22 for a trade off between power, air use and sound.  The bigger calibers are much louder and use more air.  I’ve found that .22 is plenty for me given I am shooting relatively short distances most of the time. 

Does a hand pump really work or should a person buy a SCUBA tank?

Guys, the last thing I want to do is to buy a tank and deal with going to get it filled.  I have a Hill Mk.4 hand pump and highly recommend it.  I bought it for my Gladius and now use it on the AT-P2 also.  What is nice is that the air cylinder is small on the AT-P2.  I shoot about 8-10 rounds and then top it off back to 200 BAR and that takes about 20-30 pumps.  When I see I am down to 2-3 pellets, I top the magazine off.

This is the Hill MK.4 pump.  The small bottle is Silicone Grease.  I periodically coat the shaft of the pump and the male quick connect plug.  I do it once every couple of months – not much really.

Now if you tell me you plan on shooting a ton, then you might want a tank or one of the new little portable compressors that are available.  I’m using it for pest control so my average number of shots at a time is 1-2 and then I done.  It’s easy for me to top off the magazine and the tank.

In Closing

I appreciated the folks sending in the questions and hope my answers helped them out.

6/29/2020 Update: Still very happy with the AT-P2 – it’s great on pest control with squirrels. We now have replacement fill-probe O-rings and caps to keep your fill probe clean. Click here to learn more.

Hatsan AT-P2 QE Reviews and Videos That I found Helpful When Researching My Purchase

In the old days, kids I mean like the 1970s and 80s in my case, you went to the library and read old magazines or asked your friends about what they knew.  These days, we tap into the web and can watch videos and read reviews.  I tell you, it’s pretty amazing what you can find.  So, when I was researching what small precharged pneumatic (PCP) pistol or bullpup to buy for discrete pest control use mostly in 10-15 yards vs. my .22 Hatsan Gladius Long, I hopped on and started digging.

I quickly got my selection narrowed down to the Hatsan AT-P2 QE as I mentioned in a previous post and then bought it.  What I want to share with you are some of the third party review videos that I found very helpful during the selection process.

Here’s the best video on the AT-P2 QE specifically:

The following is a review of the base AT-P2 without the integrate Quiet Energy (QE) moderator:

I hope these help you out.  I am very please with my pistol so far and would recommend anyone needing a discrete powerful and accurate .22 PCP repeater.
