Waited 2.5 weeks for the upper to arrive but it was worth the wait. Upper was properly boxed and protected in foam. Paired this upper with a custom lower (Fail Zero BCG and Geissle Trigger) and headed out to the range. After zeroing the scope it was all smiles. Easily shoots 1 inch groups at 100 yards with affordable American Eagle 556 ammo 55 grain. The heavy barrel has a nice satin stainless finish. The front grip has a stipple rubber like texture for a non slip grip. This setup is great for stationary or bench shooting as its heavy and stable.
