    Fantastic upper, and great customer service

    Posted by SEan on 4th Mar 2024

    The upper is very well made, the fit and finish are excellent. The action works very well and the latch has just the right tension. I am using this on a 45ACP CMMG RDB system and the customer support was excellent. One does need a 9mm fake gas block to allow the bolt cam pin to fit, and customer service advised me on this. They are correct. The pin can go in two ways. One works, one does not. It takes less than a minute to flip it around if this is an issue to you. Gas going backwards is not entirely eliminated but diverted much better than with a charging handle upper. What does come out, goes to the sides. I'm going to play around with some shields. I've had good luck with that on hand guns, so we'll see. Ejection is just fine with the 45ACP. Of note, this is slightly louder than a standard upper (I shoot suppressed). I have no idea why, but the side charger is definitely worth it. All in all, a super happy customer.

    I love these, I have two but unfortunately this order was canceled because I’m assuming you won’t ship to communist Washington state anymore

    Looks like this system will be better than the side charger screwed in the bcg

    I recently finished a wildcat build in .20GPC using this upper and a NFA lower. It has functioned flawlessly through all the function testing, load development and a couple of months of hunting with it. The NFA side-charging upper is the way to go if you are a hunter who uses an AR15. Hold the rifle with your right-hand, charge with the left and you're ready to go. My next coyote build will be on a NFA upper as well.

    Bought for a 6.8spc ii build and very satified with turnout. The lines are gapless and the finish is flawless. Overall function of the piece is problem free and smooth. For a more custom fire arm with slick looks and great performance this piece can be cerekoted. It looks pretty good with a utg slim keymod rail. Light weight and no need to take your eyes off the target if you need to chamber a round. Great piece.

    I have built three of these and they are sweet. No more rear charging handles for me. You can use any optic without interference. I will use these for all my future builds for myself and will be suggesting them to my customers. Plus the service you get from these folks is outstanding.

    Just put this on my build and it is a very nice quality piece. Plus it gives you that "cool" factor that many people are looking for these days with their AR's.
