This review covers the Brownells reproduction of the Colt 4x20mm AR-15 scope, manufactured using original 1970s blueprints and manufacturer. It features authentic markings, a duplex reticle, and a BDC turret calibrated for 100-500 yards. The scope mounts directly into an AR-15 carry handle and offers improved modern glass quality while maintaining historical accuracy, making it ideal for retro builds.
