Changing Springs and Buffers in My Beowulfs To Improve Reliability

Okay, so the last range trip went a lot better. The new Lancer L5AWM mags with Tromix followers worked great. The reliability on the pistol was coming along but not where I wanted it and the rifle was disappointing still but I knew what was going on.

7.5″ Beowulf Buffer Spring

My 7.5″ Beowulf pistol is running pretty well but I wanted to increase the forward force of the bolt carrier to strip the next round and chamber it. I was already running an H2 buffer but an other wise normal carbine spring. I upped my game to a Sprinco Red Extra Power Carbine buffer spring that they say is made with the “thumper” cartridges such as the .458 SOCOM, .450 Bushmaster, .50 Beowulf. I bought mine from Primary Arms.

The Mil-Spec Carbine Buffer Spring is on top. The Extra Power spring is on the bottom with one end painted red. That’s handy for knowing what spring is in the weapon at a glance.

I cleaned the pistol, lubed everything and installed the extra power spring and the H2 buffer that was in there. It definitely slammed home harder when I released the bolt.

When we go to the range next, I’ll be taking a standard carbine spring, an enhanced Sprinco spring and the carbine already has the extra power spring already installed. I’m also taking standard, H2 and H3 buffers with me.

Changed the Spring and the Buffer on my Full Size Beowulf Rifle

This rifle was built using an Alexander Arms DIY upper.

When we were shooting this, it had a hard time stripping the next round and chambering it. It dawned on me that they hydraulic buffer that I originally used wasn’t driving the bolt carrier forward hard enough. You see, a Hydraulic buffer has a piston inside that has a controlled leak down rate and, for whatever reason, it was dampening the stripping of the next round properly.

With carbine tubes, you have tons of sling and buffer options. Not so much on rifle length tubes. I did opt for a Geiselle Super 42 rifle-length buffer spring and a slightly heavier Expo Arms 5.4 oz rifle buffer –I bought both from Primary Arms.

Top: KynSHOT hydraulic buffer and Mil-Spec rifle-length buffer spring.
Bottom: Expo Arms 5.4oz buffer and Geiselle Super 42 Rifle-length buffer spring
The Kynshot buffer is very nicely made but I don’t think it’s the best choice for this application. I will save it for future projects.

When I cleaned the rifle prior to installing the new spring and buffer, the one surprising thing I found was that it was fairly dry. Why? I have no idea and this would have impacted functionality at the range also as I assumed I’d lubed it already before putting it away. Yet another example of my memory not being what it used to be.

Given that surprise, I went through and applied Super Lube oil and grease before installing the new Geiselle spring and Expo buffer. Afterwards, the action slammed home very easily.

I will take the hydraulic buffer with me back to the range for testing but am somewhat skeptical of it right now. The rifle is set for the next range visit at this point. Another Mil-Spec spring and buffer will be in the bag as well.

Conclusion

We have a ton of snow right now and I’ll have to wait to test my hypotheses. I expect that with the above changes, the two Beowulfs will run very well now.

I hope this helps you out!

Are you looking for the drill bits and end mill for your Polymer80 pistol build? If so, we have them and a sanding kit!

Folks, we believe we have the right to build our own firearms and have supported the Polymer80 Glock-style frames for a while now. You can build a very reliable and accurate pistol off of their frames

This is my favorite – a PF940v2 was used to make the receiver and it is mated to a Zaffiri Precision custom G34 slide and barrel with a Holosun optic on it. The pistol is accurate and runs like a top.

If you need the 3 or 4mm drill bits that the Polymer80 pistol frames use or the end mill for cleaning up the rails and/or removing the barrel block, we have them.

Given that I like using their frames, I also understood what was needed in terms of the drill bits, end mill and other finishing supplies. We have a number of offerings, but let me highlight our top three.

Note, we also sell a very popular sanding kit that works great for cleaning up the barrel channel so it is nice and smooth with nothing for the recoil spring to catch on. Click here for it.

I hope this helps you out.

What are the best affordable tritium and fiber optic sights for Polymer80 and Glock pistols?

A fellow emailed me wanting to upgrade his Polymer80 from the generic OEM Glock sights that I don’t think really excite anyone to something that would be more visible in general and also work in the dark. My answer was immediate – go with the TRUGLO TFX Pro Tritium and Fiber Optic Xtreme sights.

The featured photo above shows how bright they are on my P940CL that has a G17 slide on it. I bought these sights by the way – so you are getting my honest opinion.

Folks, these are my hands down favorite sights for a number of reasons:

  • They are CNC machined from steel and have a durable black nitride finish — they are not soft plastic.
  • They do not need batteries – the lit dots are via fiber optics when there is light and sealed tritium when it is dark so you are covered regardless of the light available. The tritium ought to fluoresce (emit light) for about 10-20 years and I’ll worry about replacing them then.
  • I really like the three green dot configuration – two on the rear sight and one on the front. The front also has an orange ring that you can see when there is light but is green when operating off the tritium only.
  • The rear sight goes into the slide’s groove very easily and is then secured with a set screw. Some sights can be a bear to install but not these.
  • The rear sight is big enough that it can help you rack the slide one handed in a one-handed emergency.
  • They have a 12 year warranty.
  • They are assembled in the USA – the tritium capsules are made in Switzerland.

What Glock models are supported?

Because these are so popular TRUGLO is making a variety of models to support the different Glock and Polymer80 configurations that are out there. I assembled the following table and you can also check their webpage if you want:

TG13GL1PCGlock® 17 / 17L, 19, 22, 23, 24, 26, 27, 33, 34, 35, 38, 39, 45 (Excluding M.O.S. models)

Personally, I use the TG13GL1PC on a G17 and G34 built on PF940v2 frames. I bought both off sight sets off Amazon and the following ad will enable you to order any of the above as the models are listed as options:

This gives you a better view of the sights overall. This is the TFX Pro TG13GL1PC with the fixed rear sight. I really like the sight picture these give day or night.
Here’s the rear sight and you can just barely see the set screw that secures the sight between the two “ears”. The slot at the top of each fiber optic is where it collects light to illuminate the dot. If there isn’t any light then that is where the tritium capsules take over.
Here’s the front sight. The orange ring is nice during the day and you only see the green tritium dot in the dark.
Well, trying to take a photo in the dark of three green dots with a cell phone camera was an experience. I went in a basement room and shut the door to cut off light. It’s fuzzy but you get the idea – all three dots are nicely lit in any lighting condition.

Do they have lower cost models also?

Yes, they do. The Tritium series just has the tritium for illumination in the dark and show as bright white dots during the day.

The following Amazon ad will lead to all of the above models as they are options you can select:

They also make a Tritium Pro series that builds on the Tritium base model and adds an orange ring to the front sight plus the back sight is bigger and that makes it easier if you need to rack the slide with one hand.

The following Amazon ad will lead to all of the above models as they are options you can select:

Do they support other brands and models of pistols?

Definitely. These are very popular lights given their great combination of quality at a fair price. I tend to see the best prices on Amazon so use the following search to check what they have:

Conclusion

I hope this helps you out. I really do like these sights and have no reservation recommending them.

Will A Bulgy ARM9 Grip Fit An IMI Galil? The Notch Is Definitely Different

A recurring question I get is if a Bulgarian ARM-9 grip can be used on an IMI Galil rifle. Not easily is my answer and I took a bunch of photos so you can decide for yourself. You would need to add black epoxy to the inside back of the ARM in order to Dremel or mill it open further to duplicate the swing of the Galil’s lever – at least that’s how it looks to me because I don’t own an IMI Galil to experiment with.

So, here are some photos so you can see what I mean:

Note the difference in the shape of the ARM-9 grip’s notch on the left vs. the IMI Galil’s notch on the right
Here are the notches even closer.
Here’s the ARM sitting on top of the Galil for another perspective.
Here’s where you can see that the ARM-9’s original wall design is hollow behind the notch. It’s not an impossible change – if you were to abrasive blast the inside of the ARM grip and then use wax stripper, you could then fill that back in with black epoxy. It wouldn’t be an exact color match by any means.

Summary

So there you have it. They are different and definitely not a simple swap with out doing some epoxy work and then maybe a top coat of some finish if you want the colors to match. I hope this helps you out as you think through your options.

What is the 12.7x42mm cartridge? Is it the same as .50 Beowulf?

The short answer is that they are the same thing. The bullet’s diameter is 0.50″ which is 12.7mm and the case length is 1.65″ or 42mm. The reason you see some vendors say they have something to sell in 12.7x42mm is they are trying to avoid a trademark problem with Alexander Arms. In other words, they are the same thing and people are trying to avoid a trademark infringement lawsuit.

Bill Alexander, of Alexander Arms, did all the engineering to bring to life both the round and the AR components to use it. He trademarked the term “.50 Beowulf”. As such, anybody who wants to sell something and refers to it as being for .50 Beowulf would need to get the permission and/or license the use of “.50 Beowulf” to avoid legal problems. So, a lot of vendors use the generic metric designation of 12.7×42 to avoid legal hassles.

With that said, bear in mind that not all engineering is equal. I have never had a problem with Alexander Arms parts but myself and others have had plenty of headaches with 12.7×42 components from budget AR vendors who haven’t done the engineering so buyer beware and research a vendor and their offering before you buy plus make sure they are reputable in general in case you need support.

So, short post this time. 12.7×42 and .50 Beowulf are the same round with different descriptions. but be cautious to check out vendors selling parts using the metric designation.

Here Come The Mosquitoes and Ticks! Argh! How To Find Talstar P Pro Now And The M4 Sprayer

One of my favorite move lines comes from Aliens when Ellen Ripley says, “I say we take off and nuke the entire site from orbit. It’s the only way to be sure.” While I would like to do that with mosquitoes, it’s just not an option currently.

Not on the table for mosquitoes yet though it does sound effective. The collateral damage is hard to justify though 🙂

The best approach for dealing with the little winged horrors and ticks still seems to be Talstar P Pro. Seriously, we live in an area that can described as a reclaimed swamp (it really was) and the mosquitoes used to be unbearable. I blogged about this first in 2018 about my move to Talstar and using a Ryobi battery powered sprayer and then a second post in 2019 that covered my continued use of Talstar and my purchase of a My 4 Sons sprayer.

This will be our third year using it and I just applied our first dose the other night – 1oz Talstar per gallon of water and than I go spray it on the bushes, around the buildings, under the eves etc. When I went to buy more Talstar off Amazon, they would not deliver it to my area and never really explained why so I figured I better blog about where to find it and also the My 4 Sons sprayer that isn’t on Amazon any longer.

This is the 3/4 gallon (96oz) size Talstar P Professional insecticide by FMC. I have an acre and a half. I use 10-15 gallons of spray depending on what all I am treating and how heavy I am applying it. That means I use 10-15oz of Talstar per treatment (1 oz TP to 1 oz water).

Buying Talstar P Pro Insecticide

My big problem this year that I wanted to make you aware of is Amazon – at least in my case they will not deliver it to our address. I’m getting increasingly frustrated by Amazon so I now buy it off eBay:


My 4 Sons M4 Sprayer

The next thing I want to do is give you a “one year later” report on the M4 sprayer made by My 4 Sons. I’m happy to report it has held up great and their customer service was exceptional. Note, I definitely drained it completely before freezing weather set in.

This is my actual sprayer the morning of 5/2/2020

Here are some lessons learned on my part and a couple of minor issues I encountered:

  • I bought way too much hose when all I needed was to just tow it around like a golf cart and spray stuff. I took the extra hose and saved it just in case.
  • I bought all kinds of sprayer gizmos and all I use is the wand. It has a brass tip, is adjustable and worked just fine for me.
  • The red elastic straps they provided did not hold up – the tank would fall of the cart. I just went to ace hardware and bought some 1″ nylon straps with buckles and cut them to size. I told My 4 Sons about what I did and am not sure if they changed how they are securing the tank.
  • One wheel broke and My 4 sons promptly sent me a replacement at no cost
  • The gasket on the lid was goofy and they sent me an improved model at no cost

This Spring I could not find the battery charger and ordered a replacement part from them. The price was reasonable and on their website – of course I found the original shortly there after.

As mentioned, I’ve already done my first application this year and the unit is doing great – they aren’t on Amazon any longer though. I want you to know they are a reputable firm with a good product and customer service. I would recommend that you go direct to My 4 Sons.

Just to be clear, Talstar will work in any sprayer – it’s pretty much the same viscosity as water so any pump sprayer – manual or batter powered – will work. I needed something bigger because of the size of our lot.

Conclusion

The Talstar P Pro and M4 sprayer are a great combination that I would recommend to anyone trying to deal with mosquitoes. It’s cheaper than a service and way, way more effective than the cheap stuff you buy in a store.

I hope this helps you out.

Video: Kalashnikov Concern Releases the Civilian Version of the AK-12: The AK TR3 Rifle

Because of the import restrictions of the Russian firm Kalashnikov Concern, Americans will not get a chance to see a cool new rifle just released by them. Their AK TR3 rifle is a civilian version of the modern AK-12 and will be available in both 5.45×39 and 7.62×39 cartridges. [Click here for a previous post that goes into the AK-12 in more detail.]

The AK TR3 is identical to the military AK-12. Note that it has three fire control group pins.
The AK TR3 is chambered for both traditional Russian cartridges, the 5.45×39 and 7.62×39

Here is the Video

In this short video, Kalashnikov gives you a brief overview of the TR3:

Yeah, I sure wish I could buy an AK TR3 but given the political issues between our countries, that is not going to happen. Regardless, it looks like a very slick rifle and I’ll just have to ogle it from afar.
