no but i believe the MP15-22 you can change out the furnature with regular aftermarket ar furnature.i know the colt m4 .22LR you cant even change the grip out with a different one.Not really worth a new thread so I'll ask it in here. Are the .22 ARs like just a standard AR lower with a dedicated .22 upper on them or can the lower only be used with the .22 upper. I guess what I'm asking is if you could put a regular AR upper on them too.
