I have a new carbon 15 Bushmaster (10 rnds fixed mag Ca legal) and the upper doesn't drop into either of my Bushmaster lowers and the lower doesn't
take my other bushmater uppers. I have 3 Bushmasters which are all stock but the carbon 15 works fine with the carbon fiber top and bottom but the uppers and lowers don't fit my other rifles. Has anyone else had this issue? If so were you able to resolve it? I called Bushmaster and the rep said to drill out the rear pin hole of the upper and had no clue about the lower. Out side of returning the enitre unit I'm not sure what options are left. Thanks RB
