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.
Made in the USA
