hello, anyone happen to know a working coupon code for parts dispensed? thanks

First time building a gun and working with steel. Having a blast so far, by my reckoning I'm about 16 hours in. I know that seems like a lot for 3 parts. I was relying too heavily on hand tools, so I bought and taught myself how to use an angle grinder. What a game changer that was honestly.

Those square holes itched something in my monkey brain, I could make those all damn day it was so satisfying.

Recently i have been working on a design for an open bolt SMG, nothing super creative, really just a sten with a magazine position that isn't designed for WW1 style trench warfare.

This is my first serious take at actually designing a gun myself, even if 90% of it is a ripoff a WW2 design so I'd appreciate someone more experienced pointing out what could be improved. I also do not have any prior experience with CAD so a lot of it is very blocky and crude.

It's designed for .32acp, It's meant to be made of plastic so that's why the small caliber and thick barrel. I know that 22 is even weaker but i didn't want to bother with a rimfire design. The conical end of the barrel is meant as an integrated flash hider, something like on the Breda Mod.30 but smaller for the smaller caliber.

Altough the gun is meant to be plastic the bolt would need to have a metal weight in it as even with the densest plastic it won't have enough weight to delay blowback until the bullet leaves the barrel.

I do not indent on actually building this at it's illegal and would likely explode on first round. This is just a fun project and i will probably actually make a non-firing version in near future.

I've been trying to get an idea of how it works but I can't find any resources at all, it's often left out of diagrams and such. All I know is that when you push on the ejector rod it pushes out to a point and a spring brings it back into place. The rod is able to spin but it's lateral movement is restricted somehow. This is all a mystery to me. I would like to understand how everything is connected and works together

I purchased a black one but I'd like one in fde, but I also want to keep my black one. they just don't offer them. does anyone have access to a compatible stl?

The following is that of a retard. My general goal has been to produce something that makes sense, has a hunting and sporting purpose, and is so wacky that no sane person would willingly shoot it. But I am not sane. I had a machine shop make me a trunnion, adjustable end cap, bolt and picatinny rail for this build. All barrels will intersect at exactly 100yds and is adjustable out to 150. It’s going to be the ultimate turkey/ rodent gun.

The cyberpunk volley rifle. 6 barrels of pure 5.7 copper solids. the ejector sits in the middle of the trunnion and allows me to pop all six out by pressing a button. The bolt is simply a six pin whisk looking thingy and the trigger is ripped off an r700. So yes, sometimes if you take it off safety, it could fire, technically. The six barrels are fixed inside the trunnion and spaced 5mm apart. The end cap is adjustable by way of machine screws and the way it is sighted is by shooting one barrel at a time until all barrels hit the same point of aim. Once that it done, you have a hitscan meme gun. Still need to press fit the barrels, and mill the receiver but it’s a work in progress. SUMMER RUST 2025 motherfuckers!!

Did I mention that it’s a break action? Yeahhhhhh…

If anyone knows anything about airsoft Glock conversions hmu!!!

Im looking for designs or some really good pics with the option to measure a semi trigger set for the pps43, 190 bucks if I can't but I'd like to try building my own if I could get some specs.
