Colt AR15/M4 Carbine Upper Receiver Assembly

Been waiting for these to come back in stock. Great price and shipped right away.

When looking for quality, professional grade firearms and components, Arms Unlimited is my go-to. When clients want the best AU ships quality goods quickly and security.

Item arrived with a ding as there was no extra packing around it to prevent damage in the soft envelope.

Usual Colt quality, and a decent price, considering the boys at the dancing pony can’t make up their minds whether they love civilians or not!

CAGE number, dot marked, not C marked, as in photo. I even put in the comments, "Ensure C marked, as in photo". Poorly packaged. I'll use it, but I'm disappointed.

The picture showed a "C" forge code, the uppers that arrive had the cage code instead of the "C" The 4 uppers I purchased ship in a plastic bag each upper was in a plastic bag, not the best packing in my experience. I do like the deals from this company - these uppers are Colt & are new. Thanks Kristy

Ordered and received my Colt M4 upper receiver. The item was brand new and in great condition. It will work nicely for my build. The only drawback was it was not stamped exactly as pictured in the ad. The pictured upper had the offset square and prominent "C" for Colt on the ejection port side of the receiver. The receiver I received, had the offset square and a cage code of "13629" stamped on the receiver, which is also a Colt marking. It is not a major issue, it is a Colt receiver and will work as intended, but I was hoping to get a "C" stamped receiver as listed in the Arms Unlimited ad.

Excellent Upper and Would Definitely Recommend this if yours looking for a Top Tier Milspec Upper Receiver For your Clone Build. Cage Code Square Forge.

Cosmetically and functionality are fine for the upper, but disappointing that the colt upper pictured (keyhole) is not the actual product and actually a cage code variant.
