Remember the light primer strike issue on earlier Bushmaster uppers? Bushmaster had the chambers a bit too deep and the brass was too short. It's possible your chamber is cut a hair short. It would work with the old brass, but jam up the works with the newer longer brass.

then look at the case, see if there are any shiny spots around the case mouth, or maybe heavy scratches along the case that may cause the sticking. Mag lips and barrel extensions are notorious for sharp edges.
also check your bolthead for a cracked or burred lug
