    Reviewer: Jacob Veverka from West Salem, OH United States  
    Had mine a little over a year. Had some feed issues until I used radical firearms magazine. Haven't had a feed issue since. Holds a very nice group at 100 yards.

    5 of 5 awesome March 22, 2016
    Reviewer: warren small from palmyra, ME United States  
    Arrived on the early side of 6 weeks.  Shoots and cycles flawlessly. Pinned to my lower smooth but snug, no play. Packaged well for shipping so finish was perfect. Absolutely No complaints From My end. Customer service via email was in timely manner and answered any and all questions.  Very good company to deal with and already planning on purchasing their 24" 6.5 grendel.

    Reviewer: Billy H. from Searcy , AR United States  
    Looked great out of the box I bought an Alexander Arms magazine and it ran flawlessly. Shot nice groups at 50 to 100 yards and my local indoor range. I had no hesitation to order after I bought a 300blk from Radical Arms a few months before. It took exactly two months to get but I would order from them again! Nice folks, great products and great company!

    5 of 5 Awesome!!! November 14, 2015
    Reviewer: Stacy Jones from Sunrise beach, MO United States  
    Great upper...I've had mine several months now, I'm only on my 3rd box of ammo, (50 rounds) but have had zero issues so far, with feeding or fails to eject...Using gen3 pmags... Accuracy is impressive, (350gr xpt hp AA) at 100 yards 2moa not bad considering 3 bullets touching can't be covered by a quarter. I'm only getting 9" drop at 190 yards? If I had to nitpick the only complaint I would have is to me seemed that the finish on the rail was a little soft, I scratched it up putting on forward grip. I will be buying the pistol version soon as founds are there:) ps don't stand beside gun without hearing protection

    5 of 5 Radical Firearms 12.7x42 September 9, 2015
    Reviewer: Mark Lucas from Frederica, DE United States  
    Just recieved my first upper from these guys. Attached it to a Colt Hbar lower with an EOTEC and had it cutting the same whole at 25 in 5 minutes. I have worked with and on AR platforms in the military for 20 years and this is a serious piece of equipment. The fit and finish were great better than what you would expect at the price they were offering this for. Due you'd self a favor and try one of there recievers you won't be disappointed.
