NBS 4" Slick Side Billet 9mm Pistol Carbon Fiber Upper Assembly Review

About NBS 4" Slick Side Billet 9mm Pistol Carbon Fiber Upper Assembly

An affordable pistol upper assembly without cutting corners. This means using a Kaw Valley Precision Carbon Fiber Handguard, to have one of the sturdiest and lightest possible handguards on the market, 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. 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.
