Purchase the NBS 10.5″ Slick Side Billet 9×39 416R Stainless Pistol 1:7 M-LOK Upper Assembly here!

An affordable 9×39 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 10.5″ 416R Stainless Steel Barrel chambered in 9×39, which is perfect for running suppressed. This often subsonic round is new to the American market and is perfect for home-defense, or for a truly unique build.

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.

Bottom line is this: you hear all the time about guys buying a budget upper and it not lasting or having to send it back because of some hardware defect or other issue caused by a careless assembly process. That is why we use quality components and assemble each unit to the highest standard of quality. We want your upper to function flawlessly out of the box. In fact, we guarantee it will.
