    It’s a Colt!

    Posted by Phil Herbert on 22nd Apr 2023

    I’ve had a number of Colt 9mm AR15s in both pre-ban and post-ban configurations and I even used the Colt smg professionally. Colt is one of the finest manufacturers of AR15 products in the world. While others have faltered, Colt’s steadfast quality hasn’t. This lower is no different. I had the upper on a CMMG Mk9 lower and it I wanted all Colt, and this lower fits the build with a Daniel Defense butt-stock and pistol grip trigger guard unit
