SOLD!!!!! I'm only selling this upper to fund some other projects. I have 3 other uppers I shoot more so this one needs to go to make room for a dedicated 22 upper. Vltor MUR-1A upper with forward assist AXTS Raptor ambi charging handle Crosshills Technology slab sided Nickel Boron bolt carrier with an upgraded mil-spec C158 phosphated mpi bolt Ballistic Advantage 16" 5.56 Modern Series 4150 Cmv nitrided 1/7 twist barrel, nitrided low-pro gas block (barrel was dimpled with a dimple jig before install of the gas block so it is perfectly aligned) Daniel Defense nitrided Flash Suppressor Fortis Rev II 14" Keymod Handguard (this handguard was installed originally on a Novekse Gen III billet upper which require the anti-roatation tabs to be milled down a bit. It was done professionally, isn't noticeable, and the price of the upper reflects this) Only 200 rounds have been down the barrel. Not interested in parting out. I'm letting this go for $650 which is an absolute bargain for the quality of this upper. Located in Graham.
