      Colt upper

      Very accurate but you expect that from Colt. Arms Unlimited was great to work with and even got free shipping to Alaska.

      Very happy with my purchase. I had a Colt lower so I wanted to go "All Colt". Excellent quality as you would expect from Colt. Shipping was very fast and as advertised. I plan on additional purchases in the future!

      Arms Unlimited has once again exceeded my expectations. They always have hard to find items and at a great price. Fast shipping too that cost zero dollars! This upper came perfect in the Colt Manufacturers box, manual and upper still in the Colt packaging wrapper inside. Perfect transaction and excellent upper, 2nd Colt Monolithic upper - definitely recommend this product and Arms Unlimited.

      LE6943CK

      Posted by Unknown on 8th Jul 2015

      Great lightweight upper thanks to the short barrel and monolithic design. Flip-down sights are very convenient when using red dots and optics. Metal quad rails are comfortable to tightly grasp and hold; no sharp edges or corners. Barrel profile slims down to 0.61" after the front sight. Still plenty of shoulder meat for muzzle devices and silencers.
