Folks, I am very impressed by my Hatsan airguns and have no problem recommending them. I’m rally a fan on the pre-charged pneumatic (PCP) guns that have an onboard air tank and can fire 10-20 rounds for hunting plus if you get one if their models with the Quiet Energy (QE) baffle system, they are on the discrete side for pest control.
The Gladius .22 has a 10 round magazine and is a bolt action repeater. It carries three spare magazines at the rear under the stock and they come in handy when you need to rapidly reload. It does happen with pest control actually.
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.
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.
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.
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.
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.
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.
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.
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.
