We designed the next NBS .223 Wylde Complete Upper with maximum weight savings in mind, but we also wanted to make one of the most affordable Lightweight Complete Uppers, without sacrificing the integrity of the complete upper, and most importantly the rifle. This upper features a 16″ NBS M4 barrel chambered in .223 Wylde with a 1:8 twist and a Midlength 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 the proven Toolcraft Lightweight Black Nitride BCG paired with one of our classic NBS 16″ Midlength Barrels.
The Assembled Complete Upper weighs only 3lb 11oz!!!
