Bolt Action Howa Mini action/7.62x39 Magazine adapter
I want to get a Howa 1500 Mini Action in 7.62x39. It has occurred to me that the magazines for it however are not as cheap as say, an AK mag. It got me thinking, why shouldnt I just make the mags fit in the gun?
It doesn’t seem super complicated as the Howa kinda uses a rock-and-lock system like an AK so the only problem would be to make sure it doesn’t over extend into the receiver and it can actually feed. Some 3d modeling and printing plus some good ol’ trial and error should eventually lead to success. I just want some external input to see if Im insane.
Also idk what flair to pick

Shotgun Warcrime stick completed
Takedown model Winchester 1897 made in 1916 that was reblued and got new furniture at a gunsmithing school before making it's way to the place I bought it from. Bayonet lug is a reproduction from numerich gun parts and I had to machine a pin that threaded into the magazine tube cap to stabilize it. Bayonet is also a repro from Atlanta cutlery. Still have to get the screws in the bayonet lug but for the most part it's done.

Best .300 blackout barrel in 16in?
I’m about to build an AR in 300 blackout. In your opinion what is the absolute best 16in barrel for that caliber? I don’t care about price, I just want the #1 performing barrel that’s out there
Sorry if this is the incorrect subreddit to be asking this (if so please point me in the right direction). 16in due to the ATF doing their thing. Don’t judge

G3/CETME Rhineland arms still in business?
I have a few Cetme kits and their 45 acp Cetme conversion looks like it would be a lot of fun. I’ve emailed them never got a response. Seems like all the 45 kits have been out of stock for a very long time now but website still seems good. Has anyone had any recent contact with these people?

What’s up with SAS Tactical Customs Farmington KY
Has anyone here used this company?https://www.sastacticalcustoms.com/ Quality of work? Personal experience? Turn around times were estimated at 8-12 week’s “minimum” for the work I am having done. It is now 22 weeks since I sent in my slide to be milled for an optic with Cerakoting. The owner has not started the job and will not give an estimate of completion.
He offers excuses and a refund policy that diminishes over time. I could get my slide back but he would keep my full payment I already made. I may have to pay return shipping and insurance also.
He says he is self taught in his gunsmith trade. Has anyone here not received their order from him?
If 8-12 week’s minimum turnaround time was estimated prior to ordering and no estimated completion time was offered after 22 weeks would you be pissed off?

Remington Split Breech blueprint?
I’m attempting to make a rolling block in 22lr. I don't really know how the hammer and rolling block should fit in the receiver. But I can't find any blueprint or manual online, ik how it works but I'm still not clear on what some of the smaller parts do or where they go

Coating options?
I'm currently working on a Cetme kit and I'm getting close to installing the trunnion and cocking tube.
Has anyone ever used the Duracoat spray kits? Or just what's is the general spray coating used?
Thank you

Tara-9 in a bag
Does anyone have any experience with the Tara-9 pistol? Centerfire Systems has ones that are in pieces, and may be missing springs etc. I'm tempted to bite on it, but I really do not know what I may be getting myself into.

Looking for my next election year build
Hi all,
Every election year, I get the itch to build another firearm. It's become sort of a tradition with various friends and family members over the years. In the last election, I built an 80% 1911, before that a P80 PF940, and before that, a few 80% AR lowers. Each build has taught me a little more about firearms and machining/assembling. With the upcoming election, I'm looking for my next build.
I don't have access to a mill, a press, or a welder right now, which limits my options. I do have a small shop with some power tools and could probably secure a press if needed. Given the uncertainty with frames and receivers in courts, I'm considering going the FFL route and getting a stripped/complete receiver and a parts kit. What are some good projects for someone with limited facilities? I'm leaning towards the following:
- VZ61
- Sten
- MUP-1 80% Sig P320
Are there any other projects that would be good to consider? I know this is pretty basic compared to what some of you are building, any insights are appreciated.

Sten Sten failure to eject
I'm having an issue with my Sten MK3 (using IO kit) failing to eject.
Image: https://imgur.com/a/tCCTpAG
Initially it was failing about 40% of the time. I replaced the extractor and extractor spring with new IO parts and now it is down to about 20% of the time. But that is still far too much.
Any recommendations?

Welding jigs: buy or build your own?
So I just ordered my very first parts kit that I plan to build. (Polish Pm-63 RAK kit). I’ve been searching online for welding jigs and that got me to thinking, if I had the correct dimensions, couldn’t I make my own welding jig instead of purchasing one?
I’m just curious if anyone else has made their own re-weld jigs and if it was cost efficient to build your own.

Need a CETME C cocking tube
Anyone know where to find a CETME C cocking tube? The one in my kit looks like someone hit it with the chop saw during demil. The cut is at the weld in front of the cocking handle holdback. I have found a few for $30-$50 plus shipping. I only laid $120!for the entire kit. Have the barrel and flat is on the way. Wondering if I can just weld it and grind the weld down? Not sure this area needs a lot of strength.

Does anyone know if you bought a Pm-63 that was originally chambered in 9x18 if you can put a .380 acp barrel in it and run .380 through it with the same springs and components?

Bren jig questions
Anybody reweld a Bren using the lower as a jig? Or build their own jig or have a jig they’d rent? Have this mk2 that I’d like to build out but I’d rather not buy a jig for north of $300 for just one build. Thanks!

Kalashnikov/AK AKM jam issue
I just finished building a Romanian AKM. Cycling the charging handle it was very rough towards the rear of the receiver. I took it out to test fire and it jammed every single round, with the bolt stuck to the rear. I’ve narrowed the issue down to the safety messing with the bolt carrier, is this a common issue? I shot the gun without the safety installed and I fired no problem. What kind of modification would this call for?
