      Great Start

      Posted by Yukon58 on 20th Jul 2025

      Superb start for a new build! Nothing says M4 like an original Colt Commando. Can't wait to build this one out. Maybe Retro!

      MY Favorite Lower

      Posted by Jason on 8th Jul 2025

      This is my second Colt Commander Lower that I have purchased from AU and I couldn’t be happier with the service and price. The lower is as advertised and arrived in perfect condition Thank You AU as always.

      Colt M4 Commando SBR

      Posted by Kevin on 30th Jun 2025

      First of all, the fact that Arms Unlimited has the supply of such a rare piece is just awesome. They always have the hard to find goodies that no one else can get. The lower arrived at my FFL in perfect condition and looks so sick. It is the perfect addition to my safe. The people at Arms Unlimited are great and their website is straightforward. The whole process was a piece of cake, even for an SBR. 10/10, highly recommend.

      M4 Commando Lower

      Posted by Jeff on 30th May 2025

      Overall experience with AU was great as usual and I keep coming back for Colt parts at a great price. The lower shipped fairly quickly but just like a anything Colt it had a few dings and scratches but the most annoying part was the A2 grip having heavy gouges in it but AU is sending out a replacement grip so overall I can’t complain and have been very happy with AU and their customer service.

      AU has the best selection of Colt AR products that I have found in my 30+ years of collecting. This as all items they sell is as advertised. Great products at great prices. I wouldn't ask for more.
