...that I've never seen discussed. Are AR-15 bolt carriers and bolts interchangeable? Say , as an extreme, for some reason a bolt-carrier for a 450 Bushmaster was damaged? Could you take the bolt carrier from a 223, put the 450 Bushmaster bolt in it, and run the 450-rifled barrel? Or are the bolt carriers specific to calibers as well and the 450 Bushie bolt carrier itself is bored differently somehow?
I ask because I saw a KAK add tonight selling complete BCG's and also separate bolts of various calibers. I'd never seen replacement bolts sold separately, so I'm wondering about mixing them (recognizing the barrel would have to match the bolt).
