16" 300 BLK Nitride Carbine M-LOK Upper Assembly

16" 300 BLK Nitride Carbine M-LOK Upper AssemblyA 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 that the upper will function 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.Limited Lifetime WarrantyGuaranteed Sub-MOA performance with match grade ammo and proper shooting techniqueMade in the USA
