Works well
Ordered with M-Lok hand guard 8.5" bl. Mated to PSA billet lower w/Shockwave Blade and tube for pistol build. Fail Zero boron BCG and upgrade trigger. Couple feeding problems with older metal mag. Switched to new magpuls and ran flawless. Clay birds at 200yd no problem with Leupold 1.5-5x. Shooting 120 gr Rem.

Quality upper
Purchased one of these for a pistol build back in the late summer of 2016 before the election. It's accurate functions flawlessly and sighted in fairly easily with magpul mbus sights
Liked it so much that I bought a 16 inch barreled CHF upper and PSA premium no logo bcg and Magpul butt stock buffer tube spring and buffer
Now I want to purchase a 5.56 10.5 barreled upper for another pistol build
Shipping was fairly quick customer service was great
If your thinking about buying this upper go for it you won't regret it
It's Awesome!

great value
Waited to review this upper until I had ran the pistol a bit and I am pleased with this upper so far
locks back bolt both supersonic and subs no issues with feeding or ejecting barrel looks very similar to kak value line barrels yet in a twist rate not offered by kak accuracy I am not sure about yet still need to site in but function is flawless.
Pistol was built on a PSA lowerPSA nickel boron BCGPSA LPK KAK buffer set @ 3.8 oz and ejecting at 3 o clock. or so a hyper fire edt3 trigger only gripe is I would think a PSA lower and PSA upper would match .....they do not. Minor issue but it is an issue.

Overall Very pleased and recommended.
