Awesome upper
I am impressed with the quality and performance of this upper. Just shot my first groups with it using 50 grain SBKs. Produced a dime sized group at 100 yards using only a 4x Leupold tactical scope. Light weight and amazing accuracy with a RRA lower with match trigger. The colors match up great too! Thanks PSA
