Description

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 M4 barrel chambered in 350 Legend with a 1:16 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 one of our classic NBS 16″ Midlength Barrels.

Made in the USA
