Tooreal.I see your bolt release is a Phase 5 .I have two 308's and it works on one and the other it will not lock back after last round or if single feeding .Im thinking the mass weight of the piece is too much to operate fast enough and have to figure out how to slow down the cycle so it will lock back on last shot . Any one else have that problem with this bolt release ? Any ideas ? I have tried turning down the gas and stretching the mag spring .Next maybe a heavier buffer .
