I read that in some drafts of HR 1022 (the new AWB the Dems have been trying to pass for years) that it no only bans the manufacture of AR-15 type rifles, but it bans the manufacture of replacement parts. This made me think it would be a good idea to have a small supply of the most likely to break parts. I saw that Bushmaster has a kit that has all the springs, pins and detents from the entire gun, plus a few other parts like the firing pin, disconnector and a few others. I thought this might be a good start, but I wanted to see what you guys think. What do you think would be good to have on hand... just in case?
