how the rpg 7 tube made ?

Hey Bros i'm looking for a simple trigger design for shotgun, but with only two pieces compounding the mechanism, can somebody help me? I need some images or ideas. I'm making a homemade shotgun

As the title implies, I'm looking for accurate dimensions for a sten magazine. I have sheet metal I'll be using for it but I can't find anything, or maybe I'm not looking hard enough lol but if someone can dm me some info it would be greatly appreciated 🤙

As someone who never crafted guns but knows at least few things which DIY gun i should start crafting? I tought making a rifle like k98 would be easier then making an Submachine Gun but few forum said it would not. Maybe i should start with a pistol. I would like to hear you guys toughts.

Hello friends. I have one question, what should be the spring force for a full auto 22lr ? In N/mm ?

Probably a dumb question but does anyone know a good place to buy a 50 bmg barrel for a decent price?

It will be my first time building a mag, so I would like some tips to help with the build. I trying to build a stick mag for a sten. Anything helps and is Appreciated

I had an idea to sand cast my own projectiles by designing a 9mm in fusion, 3d printing it, pressing it into sand to create a mold and then melting copper pennies that i have lying around and casting. Could this theoretically be done or would the tolerances and quality be an issue. (light sanding could be done after casting)

Im trying make an single stack Mag that holds 18 round of 22 lr, and can someone give me ideas how to make one?

Can someone tell me how to make a 9mm chamber without 3d printing?

Does anyone know how long of a barrel I need to convert a zoraki and make the barrel not stick out a little from the slide/ make it flush like the oem barrel?

Hey guys. I'm looking for an easy diy way to make compression spring from 2mm mild steel wires. Anyone got some ideas?

Just in theory. If I want to convert 9x19 direct blowback gun to fire 9PAK blanks, what ID of barrel I should make, to keep it cycle?

once more, direct blowback. With heavy bolt.

Does anyone have any idea how this trigger works? Sketches would be appreciated, thank you.

anyone know of a ruger mk cad model

I want to make an FGC-9 someday

Edit: Thanks for all of the help. 👍

As I understand it the KG-9, SM10, SM11A1, and YAC Sten MkII were individually ruled to be machine guns as the ATF determined they could be easily modified to fire full auto. They never declared open bolt itself illegal but in their individual rulings strongly implied the open bolt system in each gun is easy to modify as applied to those 4 models of firearm. As a result the industry decided to stop attempting to produce open bolts because they expected the ATF to rule their firearm a machine gun which would be a financial blow due to the cost to setup tooling and designing the gun.

However if a home builder made an open bolt semi auto gun would it be legal to posses until they get an ATF determination letter in the mail saying otherwise. That’s assuming a homebuilder even got on their radar to begin with.

Sounds risky but this type of logic is how featureless and fixed mag solutions exist in ban states. The CADOJ never ruled fin grips are alright they just never said anything to the contrary. As long as you make an attempt to stay complaint you should have a good defense. Even then in many of these cases such as the FRT people often get a cease and desist first.

What are your thoughts?
