5 of 5 Solid August 20, 2020
Reviewer: Anonymous Person from Hollywood, FL United States  
With the current climate and difficulty in finding parts, especially Colt parts, this was a good deal. It seems like the trend is toward shorter barrels now, which is probably why this was priced reasonably. But give me an A4 any day...

5 of 5 The Real Deal August 17, 2020
Reviewer: JJ from CA United States  
Not easy to find quality AR uppers right now and a Colt is even harder to find. If you do expect to pay the "Colt" premium, not at Arms Unlimited. They had the best price anywhere and exactly as described. Colt Cage marked, Colt manual,  barrel cap and extra pins for ban era Colts.
Very happy with purchase.
