I kind of want to make a prop AR15 that I can use in my military vehicles driving around. I have some parts already and probably only need a few things anyway. I have a raw unmachined lower, and an old upper. Have a stock and don’t need a buffer or bolt, or trigger, or gas tube or any springs and stuff. I would want a A1 carry handle though. Does anyone have an old A1 barrel with the triangle sight post they don’t want? Could be bent, shot out or otherwise undesirable. I also need a rifle stock tube, basic pistol grip, charge handle, delta ring mechanism, main pins etc?

Trades?
