    Brand new Piston Carbine lower. Nice rollmark; not a blem. Chalky grip. Comes brand new with Colt factory tag, great condition. AU shipped fast w/ tracking number. Will definitely keep shopping with AU in the future! Thanks!

    This is a forged COLT receiver, NO QR CODE and all markings are stamped. LP serial prefix. Very happy.

    Colt m4 carbine lower receiver assembly

    Sold. Pretty good quality for colt. Some light “snail trail” imperfections but over pretty nice. AU has the best prices for sure. You will wait about 2 weeks though for delivery. It’s a true Hartford horsey. Get them while you still can. I will continue to use AU for more purchases. This was my second purchase from this site and they have my confidence. Repeal all gun legislation! And not one more inch

    Recently decided to build a replica Colt XM177. I needed a REAL Colt lower and Arms Unlimited had the best (by far) deal going. Amazingly fast shipping to my FFL and within days I had my excellent quality, REAL Colt AR lower in hand. Thank you!!

    The sales team went out of their way to ship my order fast and it was exactly as ordered! I was excited for some of the Arms Unlimited swag that was included too! Couldn't ask for better prices or service. Thank you!

    I was concerned that at this price that this was a Colt lower with substandard parts added, fire control, buffer, etc. but was pleased to find Colt throughout. Very happy!
