NBS 16" 6.8 SPC II Carbine Quad Rail Upper Assembly

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. This upper features a 16 NBS M4barrel chambered in 6.8 SPC with a 1:10 twist and a carbine gas system. With the NBS line we wanted to make sure that we used quality products that wouldn't break the bank. This means using a nitrided steel gas block from APOC Armory as opposed to aluminum and using reputable internals like one of our classic NBS 16 carbine Barrels.
