Colt M16A4 20 inch Stripped Upper Receiver Assembly

Nice upper COLT sold us out again ,no more sale to the public i missed my chance to to own the COLT A4 but the upper gave me a clone with a COLT match target lower very happy with price fast shipping .

Awesome complete upper being used to assemble a replica M16A4 for my son as a “congratulations gift” who will soon be getting out of the Marine Corps.

I have just received this Colt upper and could not be more pleased than to see the original box with manual included , and the upper assembly. Indeed a top quality product but unfortunately Colt will be stopping ar-15 production and these will be very hard to find.

Great products at fair prices. Super fast delivery. Cage code marked receiver, CMP barrel, non-F marked front sight, for those who care.

Product is great and dealing with arms unlimited is always great also! Just wish they'd of sent a couple stickers along with my order

Everything about it is perfect, especially at the AU price. Colt made a mistake and sent out the wrong uppers causing a minor setback with the order. Definitely not Arms Unlimited's fault but they were great to communicate with and made everything right as quickly as possible. I'm happy I didn't hold off on ordering because these are brand new Colt M16A4 upper assemblies for $xxx with free shipping. At that price I'm very tempted to order another before they're out of stock again. Thank you Arms Unlimited for the excellent service.

The upper is exactly what you would expect from Colt. Fast shipping. Excellent price.

The Upper was marked with the Colt cage code instead of a C proof, barrel is C marked, chrome bore. Wish upper has a C proof, but it is the new way, Brother!

Bought on sale looks good and happy with purchase

if you are a good Colt owner and as any good Colt owner, have a minimum of a new Colt bolt/carrier assy, several actual Colt bolts, a spare Colt charging handle...you would be looking for a handy place to store those parts. What parts cabinet could be better than a Colt A4 upper new in box, and minus only bolt/carrier and charging handle, for $350?!....if you also have that fall-back carry handle, you are in 20" CAR A2/A4 heaven.....missing not a thing else, handguards, sights, dust cover, just PERFECT. As usual, this outfit a little slow out of starting gate awaiting known accessible parts, and minimal expense spent on packing milsurp spare parts, whether chunked bare in tyvek mailer, or an upper carton simply wrapped in plastic and mailed, but you WILL get the genuine Colt parts, or ACOG, or nightvision, you ordered...just be happy you can get them at all, and at such great prices...
