    Pistol Caliber Side Charging Upper

    Posted by Chris on 2nd Mar 2024

    This is my first side charging AR upper and I really like it. The overall fit and finish is excellent and the NF barrel I purchased at the same time fit perfectly (no shims or lapping required). LRBHO feature worked as advertised with stock Glock magazine and it fit nice and tight to my lower.

    PCC upper

    Posted by Stephen on 11th Dec 2023

    This side charging upper is one of my favorites for PCC builds. It costs more than a rear charging upper but by the time you buy a rear charging upper and a nice charging handle you’re pretty close to what you’d spend on this one and this looks cooler so there’s that! No issues with my 9mm or .45 acp builds. LRBHO is built into this upper, works great with NFA lowers.

    This is BADASS. Tried it out over the weekend and it reminds me of my STG58. But way lighter. Love it. Thanks

    High quality workmanship and design

    Posted by Jake on 5th Jun 2023

    I ordered this PC NRSC upper to mate with an NFA S9 lower, but they're incompatible. That said, the design is very nice and the fit and finish were excellent. I can't comment on how it worked but my first impression was very positive. As an aside, when I brought up this incompatibility issue with NFA, they send me a return slip and postage so I could get it exchanged for the correct C5 NRSC upper. Excellent experience all around.

    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.

    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!
