SKU: NBS-CU-16-GOV-MID 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.

We set out to make one of the most affordable complete uppers, without sacrificing the integrity of the complete upper, and most important the rifle. The NBS 20″ 5.56 Rifle M-LOK Upper Assembly, is a great all around upper, especially for hunting or long-range target practice. With higher velocity and a longer sight radius with this 20″ barrel, we wanted to make sure that any shooter could take this out and shoot long distances, reliably.

We set out to make one of the most affordable complete uppers, without sacrificing the integrity of the complete upper, and most important the rifle. The NBS 6.8 SPC Quad Rail Upper Assembly, is a great all around upper, especially for hunting, which is why we included a KAK flash can. We wanted to direct the blast away from the shooter, to provide for a more pleasant shooting experience. The 6.8 SPC cartridge is also great in that fact there are many different weights and grains to use for this specific upper.
