4″ Slick Side Billet 9mm Nitride Pistol M-LOK Upper Assembly
An affordable pistol upper assembly without cutting corners. This means using a nitrided steel gas block from an American Manufacturer as opposed to aluminum and quality American Made handguards, paired with a 4″ Nitride treated barrel chambered in 9mm.
This also means taking the time to ensure that the upper will function reliably. 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.
