text: And do be prepared some folks will knock your build but PSA makes good lowers, just not the best uppers, BCA makes amazing uppers for the price.... So rattle can it and call it goodI literally tested them in stupid bad conditions, ran over, buried, dropped off cliff - they hold up as good as Daniel defense - now they might wear out 1000 rounds faster - couldn't tell you but in a 15,000 -20,000 round life span,If you haven't hit your target and aquired a new rifle as battle booty by then you're prolly dead anyhow
