5 of 5 Great rifle, great deal from a great company August 21, 2021
Reviewer: Julio Rodriguez from Miami, FL United States  
Something so nostalgic about a 20” colt ar15a4. Great ballistics out of the longer barrel and what a soft shooter with the rifle length gas. ArmsUnlimited gave me a great deal and even better customer service.

5 of 5 I love this gun August 3, 2021
Reviewer: from ,  
This purchase was easy to buy and have transferred to my ffl dealer. They have very good communication too.    This is the only place I could find the full size rifle.  If you are looking for a new colt this is the cheapest place to buy one.  I will definitely be buying more colt products from AU.

4 of 5 Colt A4 20 inch July 29, 2021
Reviewer: D Gizzle from Alabama  
Lower Receiver: The stamp is solid and clear. Colt defense Hartford Conn USA. The  receiver stamp is marked Carbine. 5.56 cal and CR series. It also has the digital code you can scan for whatever. The safety selector is actually ambidextrous but smaller on the right side.
Upper : Detachable carrying handle with a square forge mark and 6/3 sights. Upper is also stamped with the square forge mark, along with their cage code next to it.
Barrel: C  stamped along with MP and 5.56 NATO 1/7. Standard 20 with FSB with (8)2 forge stamp.
Bolt: The carrier is stamped light with their classic C on the side and the bolt with MPC as always.
Im happy with the purchase. Its a colt period. The only thing that Im not happy with is it being stamped CARBINE. Its not a carbine, corporate playing politics. The model is CR6700A4 but still stamped carbine!? Who knows maybe these will be worth a lot of money one day. It's funny people bash these rifles but they still fly off the shelf.

3 of 5 Not what it used to be… July 22, 2021
Reviewer: Nicholas Green from Woodbine, GA United States  
Shallow electro pencil cage code marking on the upper. “Carbine” on the lower. No date code on the barrel. Shallow EP marking on the bolt and carrier. Looks kinda slapped together TBH. It shot as well as my 2015 A4, and that’s the only way I can justify 3 stars. For the money… I’d probably get something else. Colt ain’t Colt anymore. Hard to even know what’s sourced. Might be easier to find out what isn’t sourced…
