Please, just answer the question I don't want your tips on legal issues because at my age I'm not going to make a gunI want to go into weapon engineering as a career choiceSo again, this is for all you smug Insert swear word (And there are a lot of you on my previous questions)I want an answer, not a condescending attitude, and on the internet, anyone can use big words (as you've just seen) so don't, just don'tKeep it simple.
Most guns are made of either conventional steel, stainless steel or a special aluminum alloyObviously the steel weapons will be heavier than the light weight aluminum gunsMany manufacturers offer revolvers where the frame is aluminum alloy and the cylinder/barrel is steel to survive the high pressures when the gun is firedBack in an earler century kids often broke off a car's antennae, made a wooden frame (taping the improvised barrel to the frame) added a cap pistols hammer and a rubber brand and had their own gun that would shoot a 22 caliber rimfire round(Not safe for the intended target, shooter or bystanders!)
