check the gas block.. you may need a REALLY small allen key..
my 556 DPMS were coming loose after about 400.. I used red loctite after I did a followup function check on it.. loosen 1 screw and loctite then do the other.. you should have no issues with the MagPul.. the GI's maybe.. |

Gas key screws should not be reused. They are for one time only use. GI mags. don't have an ongoing history of continued updates |
