We start with a new Colt upper, direct from the factory which comes to Charlie's stripped without a BCG or charging handle, and customized it like a hot rot rod with new parts, so you are getting one hell of an SBR upper -- best of breed. The heart of this custom upper assembly is the Colt Commando 6933 upper, and have custom made the upper for a private collector, who wanted the very best, and now make this option available to you.
Thus, very similar to the Colt 6933 Enhanced Commando upper that Charlie's offers that has been so popular, with a great optimization for automatic, semi-auto and suppressed fire. The Colt Enhanced Commando upper features the newer heavy SOCOM profile barrel (without M203 grenade launcher cutouts), known as the FBI HRT barrel, with carbine gas system and F-marked FSB with lower sling loop. The barrel, at 11.5” with a smaller gas port size of 0.070", is optimized for both heavy rapid fire and durability.
We have added a mil-spec M4 RAS with Knights Armament (KAC) RAS ribbed rail covers (3), a Magpul rear sight, and a mil-spec nitrided carrier assembly, and a standard A2 flash hider.
