    Arms Unlimited was extremely helpful and made the buying process very simple and straightforward. I highly recommend the Colt EPR Rifle, it's accurate, durable and doesn't weigh to much.

    LE6920 EPR is an awesome deal for the price. AU is the only place to find Colt rifles in stock at a fair price. The LE6920 EPR is a good bang/ buck. AU is the only place to find Colt rifles at a fair price.

    M4 EPR

    They’ve definitely gone up in price lately but nonetheless it’s a great carbine. Colt has the recipe down very well for making a good AR. B5 stock is good and the centurion rail is excellent. I definitely recommend replacing the trigger group with a Geissele.

    Sold Setup

    Posted by Greg on 5th Feb 2020

    Found it interesting that this particular 6920 variant has a “CR” prefix rather than “LE” in the serial number. Nice light setup, with M-LOK free floating handguard.
