So I'm wavering right now on whether to get an AR-15. Partly cause of the bills in the house and senate, partly cause I like them - I just don't have much utility for one right now. Anyhow, my question is - if I buy a mil-spec stripped lower and put that together with a parts kit, can I pretty much but an upper in whatever caliber I want and have a ready-to-go system? I'm just looking at the possibility of maybe .308 instead of .223, or a 9mm upper. Not looking to go huge, but wanted to have the parts around in case I wanted one later and they are very difficult to buy. What do you think?
