Upper was built by me and works perfectly. Round count is about 30 rounds, as I didn't load a lot of blackout. 8" CMMG barrel, 13.5" rail, New Nickel-Boron BCG and charging handle. For scale, that is a YHM Phantom TI 30 cal can. Give that awesome "suppressor under rail" look that everyone likes. Rail comes off with eight T25 screws, quickly remove and reattach without turning, threading or otherwise causing problems. Easily attach and remove your suppressor. You'll need to provide your own suppressor for obvious reasons. Suppressor is not included. $350. Only trades would be an FNX 45 Tactical with cash on my end.
