I'm looking for a used, but still in good shape, Bushmaster ar15/M4 lower. Can be complete or not. Stock or no stock is fine. I can add my own buffer tube, spring, etc. if need be. I've got an awesome Bushmaster upper and it would be nice to join it to a matching Bushmaster lower. So, if you've got one for sale or trade, let me know. PM me and I'll get back with you. Thanks!
