Aug gas block removal

For those who have built a Nylaug, did you press the barrel stub out with a hydraulic press or have to drill it out?

What are you using to grind welds?

A 4 1/2" grinder seems way to big for the task. A Dremel is generally to weak unless you are doing detail work.

What are you guys using? Bonus points if it's not pneumatic since I don't have a large enough air compressor to run a die grinder, which really seems like the perfect tool.

I want to get into 3d printing the frames, any advice?

I want to start 3d printing my frames and buying the rest of the pieces, but I don't know shit about any of it. Any recommendations for where to find the 3d models and a good gun to start on? I have the printer and some pla+, I'm not looking to make things that last forever just a cheap way to get into building guns, mainly pistols

Grinding high/lows evenly

Howdy all, im working on my first Pps build and I’m having a hell of a time getting the 2 rear receiver welds ground down evenly. I bought a 3/8” hand held belt sander which is working great but I’m still fighting to get an even surface across the 3 sections and denial bar area. Iv contemplated buying one of those pipe sanding angle grinder attachments for a better radius but would like to avoid spending anymore than i already have. Any tips would be greatly appreciated!

Vz61 part question. - hammer stop

Hey all. Going through my parts kit and making sure everything is there. It seems to be complete. Question I have is on the hammer stop which is part 58 on Numrich’s (gunpartscorp) schematic. Their part listing shows a pin with a head and a groove near the tip for a detent. The part I have seems to fit and looks correct to other pictures I’ve seen online but no groove around the end near the tip for a detent? Do I need to order another or send it?

If anyone thinks Bowman’s should get a run of stamped vz61 trigger guards made raise your hand

Raise your hand for trigger guards.

They have a confab going for barrel production, let’s get some trigger guards!

Pile of Egyptian Parts

Has anyone rebuilt one of e-sarco's hakim kits? I looked at the description of what's in the kit compared to what nunrich has, and I have no idea what the "bolt locking block" would be.

Galil ACE barrel chop

Hey guys I’ve been doing some research but not coming up with alot regarding the Galil Ace Gen 1s gunsmithing.

What I’d like to do is chop the barrel down to the 12.5-13” mark I haven’t done any SBR paperwork yet just considering the project before hand.

Has anyone done this to their Galil Ace? How difficult would it be to get it done?

Also if I’d be putting the same barrel back in the receiver theoretically it should stay very close to the same headspace wouldn’t it? I’d check it for headspace before I started blasting away. Am I missing something? Or is this a relatively easy project?

Thank you in advance!! And have a very Merry Christmas!!

Glock slide options.

I have this beat up Glock 19 slide, I'd like to hear some ideas and/or suggestions of ways to refinish it. I'd like for it to be able to be done myself at home and preferably for free or very cheap. I don't have access to legit cerakote equipment, I do have a little jug of super blue, I don't have the means or materials to hydrodip. Thoughts?

Scratch build advice?

I've been interested in getting a rifle being either bolt or singleshot in a few oddball calibers, and just finally realized I don't "have" to buy a new 1500 dollar gun to go off of, and can instead build from an action...however I don't know much about gun building, does anyone have advice on how to start? I would be interested in a bolt action or single shot rifle in 338-06 or 9.3x62mm mauser and am wondering if there's anything I should know, or recommendations on what to do or how to do it. I'd be buying a barrel from a common manufacturer like Douglas or others as well.

Custom 277 Fury

Id like to build a bolt action in 277 fury and was wondering if anyone knew of a action that could withstand the pressures for the 80k psi hybrid cases. Any help would be greatly appreciated.

Need help identifying this optic

The timeframe for the use of the optic is from 1991-1995, it was used by a Croatian soldier during the Croatias war for independence. Thank you all in advance

Lower Bolt Guide Rails .....Spot Welds too NOT Welds

Ok So a couple years ago I built an M70AB2 Parts kit. Used Ak Builder flat , bent and Drilled it. Blah blah blah, fast forward to 1500ish rounds later and i have noticed the 2 forward Spot Welds on EACH lower bolt guide was no longer attached to the receiver....dang.

Looking for possible options short of cutting up and starting over ....... could I A: drill the receiver from the outside and attempt to plug weld the rails?

all opinions welcome
