      Great product

      Posted by Phillip Rapagna on 10th Dec 2017

      I only buy Colt. Running a Firearms Training School I see all kinds of AR-15 type rifles on my range. Most do not hold up to the use we require. Colts never fail.

      I've made several purchases from them, both on GunBroker and from their website. Their selection is outstanding, prices are great, and shipping is quick. If you have to call customer service they are very easy to deal with.

      USPS Delivery

      Posted by Michael Ferry on 26th Apr 2017

      You folks shipped the 2 uppers on November 21 And they arrived at my house here in Las Vegas on Nov. 29. I know there was the Thanksgiving holidays, but that seems like a long time. Thanks for asking. Mike

      Superb Upper

      Posted by Scott A on 18th Oct 2016

      I already knew this was an awesome upper because I have a 6945 SBR. That upper shoots flawlessly on a registered Machine gun receiver. I bought this one as a dedicated mate for the MG. It comes in a nice Colt upper box, with sling swivel, rail covers, manual. Great fit and finish, a superb product at a great price
