Hey guys and gals, I bought a Moriarti armament.308 and assembled it with a Trybe BCG. It will not feed correctly either because of the BCG not being the correct one for this rifle or the magazines are the wrong type. I must note I have tried two types of magazines, PMAG by magpul and DPMS-LR .308... so I am leaning toward the trybe bcg being the culprit here. The issue I am seeing is that the Carrier looks to be thicker on the bottom and not locking back far enough to catch a round from the mags to chamber. This bolt will smoothly go into battery without a mag in the rifle, but does as described above with a magazine. Any help would be appreciated, thanks
