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

M77 build question

I'll be working on my M72 kit in a month or so.

And was wondering if a m72 alignment jig would work with the M77?

I was thinking it would since the barrel lengths are pretty close.

Side question: Requiem has two types of press plates. One with two holes and other with just one in the center. Is one better than the other?

Thank you

Can I salvage this?

Recently I got this G19.5 laser stippled and unfortunately it slightly went through the frame. The guy actually replaced the frame for me, but I was trying to see if I can save this one before I throw it ina box to never be seen again.

Looking for advice for my first build!

I’ve only had stock models before, but I’m interested in building my own.

The only thing I’m really set on is being able to use my existing Glock .40S&W mags. Other than that, I’m open to suggestions, ideas, and advice!

Glock Model 22 Clone suggestions?

I’m looking to get a new pistol, but I want to be able to use my existing Glock model 22 mags.

Any suggestions for clones or builds that would take my existing mags?

WTB RPD Barrel

Hey, boys. So I'm looking for an RPD barrel. Ideally, I'd like a short one like the MACVSOG boys had back in Nam. But I'll take any RPD barrel at this point, please help.

Help locating replacement part

Hey everyone, I’m working on a Belgian made 7MM pinfire revolver. It is missing the spring/latch for the loading gate. Does anyone have a lead on where I could look for a replacement before contacting someone to make a replacement for it? I have tried unsuccessfully to make a replacement spring several times.

Making flat gun springs. Need help/ guidance

What’s up everyone. I’ve got an 1800’s 7MM pinfire revolver that I’m working on for a friend. The loading gate latch/spring is broken and missing from this gun and I’m unable to find an original to replace it with. So I’m gonna end up having to make one. I have some spring steel that looks like it came out of an old recliner that I planned on using to forge into the correct size and shape.

I’m concerned that the metal will lose its temper and no longer offer spring tension after heating and hammering it into the proper shape.

Any information, tips or tricks to accomplish this task would be greatly appreciated

Cetme C Front Sight Canted

After taking another look at my build today, the front sight is canted to the left.

Could I just remove the pin, realign the sight then redrill the hole? Or would I have to rotate the whole barrel around?

Thank you

PPS-43 semi-auto firing pin advice

Any suggestions for a source for a hammer-fired firing pin for a pps-43 semiauto bolt conversion? Should I modify the current open bolt fixed firing pin to have a firing pin transfer pin behind it? What’s the current methods out there? I’d rather avoid having to modify the bolt face if I can.

Are there any websites still selling P80 glock lowers?

Hey all, i've been wanting to get into the hobby for a while, and actually have a few 3D printed frames (DD19.2), however I really want to get a poly lower so I can edc without having to worry about heat etc, and have a cleaner finish on the frame. Obviously there are certain states now banning the sale of the 80% lower, and most websites are now either showing out of stock for the 80%'s, or they have just moved to the 76%'s. I was wondering if there were any sites at all still selling 80 percent lowers? Or if I will have to purchase a 76 percent and throw several hours into getting it right. Appreciate all help

ISO… suggestions

Hey folks, I’ve got a powerful hankering to build a 1911 in 38super. Only problem is I’ve never done a 1911, that alone any 38super… So, (no flaming please, we all start somewhere) I’m looking for suggestions on where to start on a 1911. I don’t really want cookie cutter as I’d like to eventually EDC it. I’d be ok with government, commander or even officer lengths. Not looking to sit down and widdle it out of billet as I don’t have a mill or lathe now. So, frame, barrel, slide ideas and needed DIY tooling? Pitfalls and how to avoid them? Reading and or reference materials pertaining to 1911?

Thank you, Bro. Timothy
