    6920 EPR

    Posted by Jake Adkison on 23rd Jul 2023

    Look, the EPR is a 6920 with a few extras. Parts fitment on mine is fantastic. The Centurion handgaurd is installed solidly and the Magpul Pro sights came installed. Gun was dry and gritty out of the box, but slicked up well with a good cleaning and lubing. Overall, a solid gun with good features and good parts at a good price. This was my first experience with Arms Unlimited but recommend them highly. They had the cheapest price I could find, had it in stock, and shipped quickly. Great job!

    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.

    I was very happy to get my new gun so quickly. It was shipped to my FFL dealer in less than a week and in perfect condition. I’ll definitely be buying more products from Arms Unlimited.

    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

    Posted by Christian Phelps on 9th Mar 2020

    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.
