I need to torque the barrel nut and install the new round hand guards for the 20 inch COLT AR15 Barrel. Aftermarket safety selector, trigger group, single point sling attachment on the A2 stock, Magpul trigger plate, new recoil spring and new lower receiver. Will have the single point sling by next week. Magpul Gen3 Mags. Feels good and sounds right in a hand cycle mode. Trigger is a ALG Defense QMS from Brownells. Picture after the test fire.
