    Posted by Unknown on 11th Mar 2022

    Easy transaction, fast shipping and great price. Will definitely purchase from again. Very nice fit and finish with no dings or scratches. Upper marked with key hole symbol only, no C or cage code. The upper has duel feed ramps but is not stamped M4 on the front above the gas tube. The front site post is not stamped with an F and The barrel is marked C MP 5.56 NATO 1/7. The carrier has a faint C etched on the side and the bolt is etched with MPC over A but no C or white dot. The lower has no forge mark and is laser etched with the current Carbine not AR15A4.

    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.

    I love this gun

    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.

    Colt A4 20 inch

    Posted by D Gizzle on 29th Jul 2021

    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.
