I put a magpul prs on my LR308 (bought used without the screw that comes with a new one) and the dpms stock screw was too long, not allowing the buffer to go back all the way, in turn not allowing the bolt to go back far enough for the bolt catch to, well, catch the bolt on the last round. Found a shorter one at Ace hardware and it's flawless now. If the above issue doesn't work, try backing off the stock screw and see if it catches when you cycle it by hand.
