  1. Jason (verified owner) –

    Great upper receiver and barrel! My KAC rail fit perfectly. I have to give 4 stars because it did not come with a front sling swivel, but it shows one in the pictures. I needed that for certain sling setups.

    I ordered this 10.5 upper a few days went by and it showed up on my doorstep, like a kid on christmas I was excited, I opened the nicely packaged box and pull out my sweet new upper. But I notice one of the parts was missing, which isn’t a big deal I simply took a picture and sent them an email to them, the next morning I receive an email with a tracking number for the missing parts, this is the customer service all firearms websites should strive for. now that my upper has all of its missing pieces and I have about 500 rounds through it already I can say that this thing shoots as smooth as a 16in upper receiver. would recommend for a clone build or a very good “budget” and I use that word lightly build.

    Clover leaf groups at 100, you can’t buy the components for this much, buy now.

    Would have been 5/5 but my order came incomplete and had to be shipped back. However, the customer service is excellent and they corrected the issue. I will be using bkings again in the future. Thanks guys.
