16" 300 BLK Nitride Carbine M-LOK Upper Assembly

16" 300 BLK Nitride Carbine M-LOK Upper Assembly A quality 300 BLK upper assembly without cutting corners. This means starting with a top-tier mil-spec forged upper receiver, using a nitrided steel gas block as opposed to phosphate or aluminum, quality American-made M-LOK handguards, and one of the nicest nitrided A2S you'll find anywhere. This also means taking the time to ensure the upper functions reliably. You see plenty of pistol 300 BLK builds, and we wanted to make something different without losing what makes a 300 BLK build so unique. We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the properly torqued barrel nut and muzzle device. Guaranteed Sub-MOA performance with match-grade ammo and proper shooting technique Made in the USA
