    This upper was out of stock when I started looking at it. I signed up for email notification and once in stock I ordered right away. First off, it shipped same day and I had it a few days later. Next, quality and finish are very nice-great craftsmanship. While this is the first part of my AR9 build, I had a buddy put it on his no-name PCC to test the LRBHO (which he doesn’t have) and it works great (I think he’ll be buying one). Last I’ve shot the company a few emails and I always have received a fast informative response. Great job guys!

    I own 3 of your side charging uppers. One is 556 and one is a side charging Beowulf 50 cal.
    I just purchased the pistol caliber side charger to build an AR-9. I am putting it on a lower with a Sylvan Arms magwell conversion block. I got the upper barreled and completed including a Sig Sauer Romeo5 optic.
    Imagine my dismay/disappointment when the upper and the lower did NOT work: with pivot pin in place, if you try to close it onto the lower the upper hits the conversion block. I had to use a Dremel tool to modify the upper to get it to close all the way and engage the takedown pin.
    Great quality upper just like my other 2 but people should be ready to do some gunsmithing if they intend to use this upper with the Sylvan mag block.
    I still have not been to the range and am hoping my modification did the trick.
