I was recently given a box of m1 carbine parts including a barrel, bolt assembly and some other bits I coudn't identify offhand, but all were in primo condition. Is it worth trying to build a second carbine out of them, or would I be better off keeping them for spare parts? I don't really need it to be a military replica with all matching parts and numbers, I already have one of those. I just want a shooting rifle I can take out and enjoy without worrying about damaging history. where can I find a receiver? it can be a replica for all I care, as long as it works.
