I am sure I have commited a mortal sin, but I mated a Bushmaster (complete) lower with a wilson upper (standard A-2 with carry handle) and barrel (Shorty) assembly. everything fits together like a dream but I am having a serious feed problem. Wolf amd PMC wont feed at all most of the time. Remmington and Winchester feed most of the time but it still jams far too often.I dont know if this is a cross breading problem or what. I have tried different mags (Thermold, new steel, USGI) no differance. with and without accuwedge, same, same. I have used this combination on others that I have built and hand no problems.
Oh great gurus of the the black rifle help me!!
