At least I didn't use a gun. Because then I could've hurt somebody! Or better yet, take a salvaged microwave, turn it into a spot welder (if you're careful enough), melt down some stainless steel cell mirror plates into a sandbox constructed from a cardboard box eith two clear plastic trash bags inside it with wet sand in it shaped from molds made from scrap plastic (ajax bottles, peanut butter/jelly jars, etc), cut and then hpt glued together for the replica gun that releases a bolt using plastic assembly, then use these parts to make the impressions in the sand to melt the steel plates down inside and let them harden and dry and can be used for components. You'll need an upper receiver, a lower receiver, a spring and spring bar with bolt in the back barrel, an end cap, holes on the right side and bottom of the back barrel and upper/lower receiver for the magazine insert and extractor, a bolt (which latches onto back barrel through "guardrails" grooves on bolt knobs), a front shooting barrel (9mm/.380 ACP; smoothbore) with screw-ins for the front and back barrel, back barrel and endcap and endcap and rear upper receiver. Use JB weld or spider webs to attach upper and lower receiver. Give it a thumbrest at back of lower receiver grip. Use backpull "ring and spring" style trigger mechanism that consists of two iron plates over a steel spring (made from the sandbox molds weakened with coca-cola or piss so it can stretch) jb welded together in place over two of the three smaller, thicker spring loops surrounded by bigger ones to the front and back to pull the trigger through the back loop, pulling back the sideways facing spring bar inside spring coil and pulling down upward facing spring bar, cocking down cross shaped hammer using two claws from springs extending to the arms of this "cross", cocking it down inside a spring, separated by a "wall" in lower receiver. When you release trigger it'll pop back in place over the front two smaller spring loops pulling the sideways facing spring bar forward in a stabbing motion, pulling the upward facing spring bar back up along with the hammer that's designed to catch it if you release it and pull it back into place. No safety, just a trigger. Use grooves in the floor of the lower receiver to snap the trigger/spring assembly. For the magazines, use an elevated follower, a flat piece of metal that goes underneath it that you jb welded, and an accordion shaped "mainspring" that folds underneath it, connected to a another flat piece of metal underneath it jb welded together, then Jb welded to the bottom of each magazine in the assembly with cupper lipped edges at the top of each magazine that's just wide enough to wedge a round through and just close enough to hold it in place from underneath. It comes in a 40 - 60 round twin stack design. Use springs and trapezoid shaped "clickers" that pop in place inside grooves inside the magazine well of the lower receiver, and in this design, the magazine well and pistol grip are two separate components, and you hold onto the mag well as the front grip. You can use brass and lead plumbing pipes to melt down as bullet and casing molds for the 9mm/.380 cartridges. Use the right millimeter dimensions for round and use matchbox powder for the shock sensitive primer and propellant. So that when you release the trigger, it'll pull down the hammer and let the bolt go forward to load, fire and extract each round of the magazine with each casing going out the extractor (which is an open rectangular slot in the back barrel and upper receiver), and bullet going through the smoothbore barrel, using trash bags as the over-the-shoulder concealed carry holster with pockets for grip and mag well on the front and pockets for 5 magazines and the ramrod stick for clearing the feed made from a cut down broomstick, hidden underneath a shirt and jacket. It's an open bolt SMG made without a mill, lathe or any other factory equipment.
Anyone can make these. Gun control laws are not gonna undo that. PRISONERS can make guns (single-shot or open bolt SMG).
