I have a Bushmaster XM15-E2S and for the last year and half it has worked like a charm. In the last 2 months I have noticed about every 100 rounds the bolt carrier key screws loosen up so much the rifle stops loading the next round. I disassemble and tighten and then it works perfectly for another 100 rounds or so. I am hesitant to put something like locktight on and am thinking about just trying some teflon tape. I saw a previous post where someone suggested just ordering new screws --- will that solve the root issue?? Anyone have any experience or suggestions.

Torque to the spec. (38 to 40 inch/lbs. I think--double check it) and then stake them.
