PSA Had Both Yugo M70B1 and M70AB2 Parts Kits – But Are Sold Out Now

11/28/2020 – This is an old post. Please note that both kits are sold out at PSA. I would be highly surprised if they get more in but who knows.

Hi folks, I’m a fan of Yugo AKs and have been for some time. I wanted to do a quick post to let you know that both fixed stock (M70B1) and underfolder (M70AB2) kits have hit the market at a good price. You will need to build/buy a receiver, barrel and 922r parts to complete them.

Here’s a photo from PSA of one of the M70B1 kits. Click on the image to go to the order page.
This is a photo of one of the PSA M70AB2 underfolder kits.

If you are interested in building a Yugo AK, you might want to consider snagging one of these. I suspect they will sell pretty quick.


As a reminder, PSA has their own line of AK rifles and accessories in case you want to check them out.

4/24/2020 Update: I received my M70B1 and it was in pretty good shape and the numbers matched. In other words – it’s not all rusted together. All the parts are in one bag and the wood is dinged up but it’s buildable. I hope to get some photos later — let me put it this way, I’m debating whether to buy a second or not.

Two Great Videos Explaining How Roller Delayed Blow Back Actions Work

I’m a fan of the Roller Delayed Blow Back firearms for a while and have had opportunities to own and shoot ones from HK, POF, and PTR. I knew the rollers were locking the bolt head in place but never really understood the details of the action. I’ve tracked down two great videos to help show you what is going on.

This is a PTR PDWR in .308 – basically a cut down HK-91 style pistol with a SB Tactical SOB Brace and a Vortex Optic.

Forgotten Weapons

In this short video, Ian @ Forgotten Weapons does a great job explaining just how this system works.

MouseGunner

This is one of MouseGunner’s cool x-ray renderings where he shows the MP5’s action at work. He’s done this for other weapons as well and watching the weapon operate really helps.


I hope this helps you out. Be sure to subscribe to both guys’ channels – Forgotten Weapons and MouseGunner.

Great Deals On Pistol Braces and Pistols With Braces At PSA

When the ATF reversed the ruling about braces and enabled folks to use them however they saw fit, the demand and supply of pistol braces went into orbit. I have carpal tunnel and a hereditary tremor so for me, using a brace is the only way I can wield a heavy pistol – such as one based on an AR, AK or MP5 type of action.

Examples of Braced Pistols

SB Tactical’s PDW brace is great on AR pistols
IWI Galil Ace in 7.62×51 with a SB Tactical SBA4 adjustable brace
PTR PDWR .308 pistol with a SB Tactical folding mechanism and SB Tactical SOB brace

Palmetto State Armory (PSA)

PSA has come a long way. I’ve used them as my go-to AR parts supplier for years and now they have great deals on parts, kits, receivers, and firearms. They also offer some great deals on braces – by themselves as parts, as part of a kit offering or even on firearms.

Brownells Has All Kinds of Metal Finishes And Surface Preparation Supplies

Folks, if you are looking for supplies to finish your firearm, Brownells is a great source. I’ve done business with them for years and they have provided me great technical support as well as customer service. If you are considering a spray on finish like Alumahyde (their own product), Cerakote, Duracoat, or Gunkote plus other finishes like cold bluing, hot bluing, color case hardening or parkerizingBrownells has a ton of options for you.

Both of these rifles were finished using Duracoat’s spray on finish. You really needed to blast the surface, make sure it was very clean and then allow the finish to cure for a week for it to be durable.
Baking on Molyresin over manganese park. That’s a M92 with a long barrel in the front and a M72B1 in the rear from back in the days when I had free time 🙂

These days, I do a base surface preparation of manganese parkerization and then Norell’s Molyresin on top. The park creates an ideal surface for any sprayed on finish like Alumahyde, GunKote or Molyresin to stick.

The following are some great examples of products they carry:

My Favorite .50 Beowulf Muzzle Brake

I now have built my second Beowulf and guys ask me about the recoil all the time – the short answer is that it’s very manageable. With just a bit of tuning, I’d put it somewhere between a 20 and a 12 gauge shotgun shooting 2-3/4″ magnum loads. Now that there are a ton of options both from Alexander Arms as well as generic 12.7×42 uppers (the metric designation for the Beowulf so they don’t have to pay royalties to Alexander Arms), a lot of guys are getting into the .50 Beowulf cartridge and ask me about what brake to run with.

My favorite is the Timber Creek Heartbreaker. It does a remarkable job of venting gasses backwards to compensate for the recoil it would otherwise have. I liked it so much on my first build that it was what I used in my second build. It’s very affordable and I’d be surprised if you can find a brake that does a better job!

Side view of the Heartbreaker and you can see where it gets its name.
View from the top. Note the brake includes a jam nut.

Finding The Brake

You may need to go direct to Timber Creek. Primary Arms is out of stock and they are sometimes on eBay.

My Alpha Wulf

I did a series of blog posts when I built my second rifle. My pet name for it was the “Alpha Wulf” or the leader of the pack. It’s all premium parts and probably my best AR build when it comes to paying careful attention to details during assembly. Here are the posts:

I’m a big fan of the .50 Beowulf cartridge and hope you find this post helpful!

3/6/24 Update: I’m not sure if Timber Creek is still making these or just what. I haven’t built a Beowulf for a few years and don’t have any alternative suggestions.


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.

Why Does the Color of Grips and Handguards From Ronin’s Grips Fade And What To Do About It?

I’ve had guys ask why the color of my grips or handguards seem to fade with time. The short answer is that it has to do with the liquid wax finish oxidizing and not the plastic – the color is actually in the plastic. You see, we sand every grip and handguard to get rid of mold imperfections and then we blast each with abrasive media (currently it’s Black Beauty or Black Magic depending in the store I go to) and that turns the plastic almost white as you can see in the photo above. We blast the surface to create a very sure grip when you grab hold – your hand doesn’t slide easily. The polished finish we used to do resulted in a surface that is slick when wet due to sweat, water, blood, etc.

So, the blasting abrades the surface and messes up the colors being reflected back to your eyes. To solve this problem, I tried a ton of different oils and waxes and the best was Atsko Sno-Seal. It really brought out the color and it did not fade – or at least I never saw it fade. The problem is that Sno-Seal is a paste wax and I have carpal tunnel. Rubbing it into grips and handguards every day over and over was killing by wrists so I had to stop it.

This pushed me back to the drawing board and this time I looked at liquid waxes. Some of them really smelled as the liquids evaporated and the best option I could find find was the various butcher’s block finishes that combine mineral oil and a wax – often a bee’s wax. This stuff goes on like a dream but does fade with time. There’s nothing wrong with the color – it’s just the finish oxidizing and drying out.

What to do about the fading?

As mentioned above, the finish I apply will fade. The good news is that the owner with a number of options and I’ll shorten it down to the four I recommend:

  1. Buy Sno-Seal and apply it. This stuff is awesome for boots and I actually had it for my boots when I tested it. It’s my #1 recommendation and what I do for furniture I make for myself.
  2. Shoe polish holds up really well and you can nudge the colors/hues one direction or another depending on the color of the wax. This goes on pretty easy and seems to last. Just buff it well so you don’t get any color on your hand. I’ve had very good luck with Kiwi products.
  3. Any fine wax for boots, leather, wood or preservation ought to work. Just follow the directions. Absolutely do not use super thick floor wax or it will be a disaster as one customer found out.
  4. Put another coat of butcher’s block conditioner on it. Easy to apply but it will not last.
Atsko Sno-Seal is my #1 choice. Kiwi shoe polish works great. Howard’s Butcher Block Conditioner is what I use in production and is also what fades with time.

How to Apply Sno-Seal

My first recommendation to customers is always Sno-Seal. It takes just a little it to polish a grip or handguard plus you can use it to waterproof your boots.

I did this corner at room temperature and you can tell it takes a bit more effort to rub it in and buff it off.

You can either warm it up on your hand and then rub it in or you can use a heat source to warm up the grip or handguard just a bit – meaning warm to the touch not hot – and it goes on even easier. When I did the M72 hanguard set shown, for example, it was warm after about a minute and 20 seconds in our microwave. You rub the wax in and buff it off – done.

Hello Mr. Microwave! You can optionally warm your piece of furniture up with a microwave, oven turned on at 150F or less, hair dryer, etc. You want it to be warm, not hot. If you can’t pick it up, it’s way too hot. The plastic will not begin to deflect until around 250F and there’s no way you can pick that up hence the rule of thumb. [Click here if you want to read about a heat test we did]
So here’s the finished handguard set after I buffed off the remaining wax.

Again, if you ask me what I do for my own grips and handguards, it’s Sno-Seal and I rarely use extra heat – usually just I just warm it up with my hands and rub it in. Sno-Seal lasts the best of anything I have found.

I hope this helps you out.

Photos of Rick’s Polish AKM-Beryl Transitional Rifle

Rick sent me these cool photos of his new build and I had to share them. He also gave me some details as well.

The rifle has a “Polish FB Radom barrel, trunion, and optic rail. Childers polish cg1 receiver. To stay with the polish theme, I found an unissued polish soviet era laminate stock. I was originally going to use a bakelite grip. But, since this is a hard use rifle. I wanted something more robust. But correct for the polish theme. Your grip delivered and then some. So here are some pictures of my polish AKM-Beryl transitional rifle. At least I call it that for lack of a better term. “

Yes sir Rick – that is definitely one slick build!
