another question, its a kinda dumb one. I have a bushmaster ar 15, i bought it ready to shoot. Im building my first ar now and just received the lower build kit. The stock that came with it is a blackhawk and is advertised as a milspec stock. I tried to put it on my bushmaster and its really tight, i can kinda force it on but not usable. no big deal cause it fits on the buffer that came with the kit. My question is the commercial and milspec buffer that close to the same size or whats the deal?
