Colt Piston Carbine - A+
Once again AU has been a pleasure to purchase from. They always seem to have hard to find Colt parts and offer them at fair prices and ship pretty quickly. The only complaint I could have is that they dont offer the matching Colt 6940P upper for sale as well (I know they are only available to LEO now).

Super Fit & Finish
Very well pleased as looks like new and best finish on a Colt that I have seen with no mars or scratches. Fit & finish is top notch and hard to find Colt lowers now. Thanks!
