    NBS 16″ 5.56 NATO Midlength Nitride M-LOK Rifle Kit w/ PA Microdot Sight

    NBS 16″ Gov Mid M-LOK Upper Assembly

    A quality 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. 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 top tier 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.

    Buy with confidence, this upper is backed by our 30 day satisfaction guarantee. Buy it, run it, abuse it, and if you aren’t satisfied you can send it back for a full refund.
