11.5" Slick Side Billet 5.56 Pistol M-LOK Upper Assembly - 9533

11.5″ Slick Side Billet 5.56 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 11.5″ Nitride treated barrel chambered in 5.56 NATO.

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.
