Reading about the problem on the net, its a common problem with all pistol calibre AR type carbines due to the difference in lengths of the pistol rounds and the 5.56 which results in the bolt getting a run up on the bolt catch and giving it a good wack.
Hope to run some rounds through it tomorrow to confirm it locks back correctly on the last round. Works fine when racked by hand.
