what im thinking of doing for closing up the receiver is instead of making the trigger housing more complex than it needs to be just to close up the receiver and hold everything together that it might be much easier to do something similar to an HK in which a block of metal made to fit inside the back of the upper could be easily made and held into the upper with pins, similar to the HK, this could also combine the guide rods and their rear plates as well and simplify things a bit more



obviously though certain functions are unnecessary for such a simple build such as the bolt catch/release which would be purely optional but the goal of this particular design remains, to be something, just about anyone with the simplest of tools can construct from 0% to 100 without the need for a mill or lathe



so this has me wondering if the lower should still be designed to use AR trigger parts or something similar to make from a block of metal.. though the AR group doesnt appear to be all that complex that someone couldnt "carve" one out even with just a little free-hand grinding, one thought i had was to eliminate the hammer entirely, fix the firing pin to the carrier and hold the carrier itself about 1/4 away from the barrel extension after the lugs have fully locked to use the carrier as a striker, combing those roles into the same component
