Just installed this week and spent the morning at the range. Installed as free float and adjustable gas block. Used Surplus Ammo upper and lower and I'm very impressed with the fit of the items seeing that I ordered it all months apart. Back to the barrel. 100 yard zero with Tula ammo created mixed results. Fliers every now and then. Cooled and cleaned the barrel and changed to Remington Core Lokt soft points. 4 shot group under 3 inches. I'm impressed for my first AR build.
