Ghost .300 blk upper - Ghost Firearms Upper Receiver, Pistol Lower Parts Kit, .300 Blackout, 10.5in Pistol, Moly Steel Barrel, 1-8 Twist, M-LOK Free Float Hand Guard

The fit and finish on this upper are very good. The cerakote is well done, everything is put together tight and properly. The bcg finish is very gritty, and initially the gun would not cycle 220 sub sonic ammo. Lighter supersonic loads ran fine. After the first few mags I broke it down, cleaned it, now it runs everything just fine. Too early to say much about long term reliability, but so far it seems good for the price.
