    Seems good for the price but looks different than picture

    Posted by Grant on Apr 1st 2020

    For the price, this appears to be a pretty good .300 Blackout Upper. The hand guard looks nice but instead of the alternating up and down triangles as pictured, mine came with 45 degree angled openings. Still looks cool but not what I was expecting. Aside from that, everything else seems to be the same. However, the gas block seems to be very close to the bottom of the hand guard. This is causing me to have some trouble getting a Magpul rail cover to properly attach directly underneath it. I haven’t had this issue with other hand guards and they typically leave a little more space. The barrel is 16” PLUS the length of the muzzle device. This is because the muzzle device is removable. Everything else aside, this drops in nicely to any AR-15 lower receiver (as it should). Fits like a glove to my FN 15 lower, to ranking, no shaking, although I will likely get a separate lower to attach this to permanently.
