Just got done with my 9mm AR. CMMG Upper, LRB lower. Forgot about the pistol caliber weight buffer. It fires one round, then the bolt carrier is extremely tough to draw back. Totally stuck. Had to take it apart many times. When I did get it apart, the spent casing was still attached to the bolt face. Does the extra buffer weight keep it into battery long enough for the round to completely discharge? Can a standard carbine recoil spring be used? I have a dedicated 9mm hammer, everything else is good. I'm hoping it's just the buffer. Thanks.
