It's been awhile since I was last on here and also since I have shot last. Had a really bad year last year with the passing of my fiancé and at the same time loosing everything at the same time. Any how I am starting over fresh and just built this AR15 and went out back. First 6 shots after sighting in were I wanted it (I never sight it for bullseye for groups). Not bad for PMC X-tac XM193 55gr. I can tighten these up easily just by shooting more again.
