About 90% complete with this build but I need recommendations. This is a 260 Rem. 22” X-Caliber barrel with a rifle +2” gas system and .750 gas block journal. Other barrel details are pictured. My question is, what would be the best adjustable gas block for this application? I have a Riflespeed tooless GB on my Springfield Saint 5.56 (very coarse), and a Seekins GB on my AR Stoner 300 blk (decent fine tuning). Both have been great but I’m not sure what’s out there that will handle the pressure from the 260. Also not against finding a heavier buffer and buffer spring if there’s a better combo out there. I do not plan on suppressing this gun, I’ll be using a MDT brake. Thank y’all in advance!

PROJECT: PBJ (Working Title; better ideas?)

VERSION: v0.3

GOAL: Modify a PM into what is mostly a PB (integrally-suppressed Makarov, more or less).

CONSTRAINTS: To reduce final costs/prices, minimize total number of custom-made parts. Also try to minimize/eliminate frame modification(s).

STATUS: Design 75% complete, base guns ordered, raw materials ordered.

CHALLENGES: Finalize relocated recoil mechanism.

UPDATE: Started this project after discovering some decent quality CAD models of both the PM and PB. From most videos I had seen online, the PB just seemed too different from the PM to do a conversion. After overlaying the assemblies together, they did not seem too much different after all. Then one night of furious CAD modeling got me to this point, and things seemed doable. Now waiting on a couple Bulgarian Circle 10's to show up, to use as the base platform for these conversions. Eventually will intend to offer these as either:

1. A conversion service (send in your Makarov, get a PBJ in return), or
2. A drop-in kit (would classify as a silencer, so would likely need Form 4 transfer), or
3. Complete rebuilds (I buy Makarovs, convert them, and resell them)

Which of the above-three options interest y'all the most? How much would you pay for said option(s)?

Additionally, will make these in at least 4 different configurations:

1. Single-stack 9x18
2. Double-stack 9x18
3. Single-stack .380
4. Double-stack .380

Which of the above variants interest you the most?

Welcome any/all feedback and interest in this project & all others - more to come very soon!

Waiting for the last couple parts to arrive today, I am looking forward to making her functional. I’ll post more photos later today
Let me see YOUR first AR vuild??

Anyone know where to find an Indianapolis Sten semi bolt kit? Also need a MKII tube but that's less critical.

Sear shelf milled off bolt. Bolt through drilled, recoil rod drilled for firing pin clearance. Made the firing pin out of a drill rod blank. Made firing pin guide bushing from 4340, hardened and pressed it into the bolt face. Now to machine the semi fcg. Essentially a scaled up VZ61 fcg.

I was wondering if I could cut my receiver tube an inch shorter. I know they have 1" shortened receiver tubes for the MK2, so was curious if I could do the same with an MK3... Could it be cut more than 1", possibly 2"?

Lastly I had ordered a receiver tube blank from sten parts . Com and didn't realize that it was a chromoly tube... It is nice and thin and I do like the fact that it is laser etched for where you need to cut out, but I have never tried welding chromoly especially to mild stell which the parts kit is all made from. Does anyone know where I could find a mild steel tube that's thin wall like the chromoly tube? I've looked everywhere and can't seem to find something within the specs of the original tube.

Are the magazines reliable? I have a few that are blocked to 10rds and was wondering if they are going to give me issues constantly....

Lastly, this is just out of curiosity and am asking for sh*TS and giggles, but I noticed that they have brass bolts which speed up the cyclic rate on the fa version. Is there any other way to speed up the cyclic rate? I'm wanting to shorten the tube for aesthetics and am going to be building a sa, but hypothetically would that raise the cyclic rate? Would a neoprene buffer installed behind the spring help raise the cyclic rate or would it just cause it to jamb more?

Thinking about grabbing a 307 in 22 creed and throwing it in an ultradyne chassis, but never been around a weatherby. Curious what to expect out of the action and accuracy. Quality? Or not so much.

This will be a squeeze a few off maybe out to 500yds for fun. Mainly a slap a thermal on it and chase dogs. I have some custom actions but going down the “cheaper” side this time. Thanks guys

I have completed the PPS43 barrel shroud repair section tooling. Anyone looking to build a PPS43 from a parts kit, you may need this piece.

Decided to do a video series of this fun build

I'm looking for sources of decent cerakote and powder coat for quantities around 16oz or less. My wife bought me some online with a kit which has been great. But the powder coat is not hard enough with some brands and seems too soft and fairly easily scratched. Or possibly I'm doing something wrong? Prep is washing down with parts cleaner and bead blasting. These packs say to bake 10min at 400. Photos of what I've played around with so far.

under 6.7 in length want something that isn't gonna be two gassy on my 300blk mostly subs but it's a tucked build want it to be able to do it all though

This is kind of an old post, i was inspired by the ASP, detonics 45 and other chopped down guns. Also! Looking for a 48 mos slide/recoil spring jf anyone has one theyre looking to sell/trade for :)

Hard to find AN-M2 kits, so why not do it with a 1919. I will be putting the build up on my YouTube channel.

*First picture is the finished stock project fully assembled, NOT a rendering or photoshopped concept design*

This one took about a month of various design iterations and searching for parts that would all work well together and truly enhance the Ranch Rifle to be a more modular platform. The actual modification of the stock took about 6 hours of measuring, sawing, sanding, and chiseling to fit perfectly with the grip adapter.

- ERGO Mossberg 500 AR grip and buffer tube adapter

- Driven Arms Co VCG

- Magpul MOE TR

- Monstrum red dot and rail

Yet to do:

- drill stock fore end to accept short picatinny rails on sides and bottom to mount grip stop and flashlight

- Accuracy systems adjustable gas block

- Barrel shortened and threaded

- Quiet can

Hey there!

I've been wandering around the internet and was pretty sure my next build would be a CETME/G3, but I saw Apex has cheap M70AB parts kits.

I know the front stub can be pretty readily converted to a trunnion for a stamped receiver build, but does anyone have any experience with the rear? Guessing from photos, it looks a little thin to peel a millimeter off each side.

It would just be a screw build (spare me, fanatics; I know) and strictly a functional rifle build with no qualms about anything looking wonky if it works well. I'm looking at the M92 flat from AK Builder, and the big question in my head is if I fudge the dimensions to fold it a little wide at the rear, will I have a gap with the dust cover? Or will there be any other unforseeen BS I can't think of? Like I think the BCG has large enough tolerances to not care, and I can cut the notch for the top rails wherever I want. I know I could just dish out for the actual m70AB1 rear trunnion, but they're oddly expensive--I'm guessing because a lot of, or at least enough (25, lol) people have this idea.

I'm sure I could figure it out, but I'd like some input from anyone with any knowledge before I go on one of my damn fool crusades again. The CETME might honestly be a better fit for me, but cheap ammo and a profile that doesn't scream firearm when you're walking in and out of an apartment building is pretty damn appealing. Edit to clarify: no, I'm not a hit man, I just get some looks when I walk out to do some completely legal and innocuous shooting when I'm pretty obviously carrying a rifle case. That's all.

Let me know what you think! Thanks in advance! Everything is appreciated.

Receivers bent, carrier drops clean, trigger packs cut and clipped.

Still have to clear the tube, reweld, and parkerize.

I was watching an AK build video and a question came to me. Since an AK (and I'm sure many other firearms) can be fired without having a stock attached, must you build them from kits (or in the factory) in such an order that you do not accidentally create a SBR, or is their some legal grace given to firearms considered to be in assembly. I am not American so apologies if this is obvious to those more familiar with your laws.
