So I get my fresh out of the box SOCOM CQB to the range with NATO 147gr MEN and had a recurring problem with the bolt locking hard to the rear after last round to a point that normal action would not free it. After a soft push on bolt face exrtractor with a flat tip, the bolt would Action forward in a normal manner. When inspecting the bolt group, it looked like the bolt shifted and binded left to the point it pushed the action slide out of position. This happened even after applying generous amounts of lube. Has anyone else had this problem? Total rounds today=20 and only loaded 3-4 rounds in mag each.
