Last round bolt hold open fail.
#1
Looking for suggestions on what would cause a ba Hanson 16" MLGS 6.5 grendel to cycle all rounds but, the bcg hangs up on the last shot. GB is nonadjustable and drilled and pinned at factory. Gas port measured .060"

so after changing out mags the bcg rides over first round because not in the most rearward position.

Is this just wear in lube issue? Less then 50 rounds on it. Tried e lander and cproducts 10 round mags.
