Who doesn’t like a nice quad rail This upper also features a 16″ BCA barrel chambered in 5.56 NATO with a 1:7 twist and a carbine length gas system. With the NBS line we wanted to build an affordable upper assembly without cutting corners. This means using a nitrided steel gas block from APOC Armory as opposed to aluminum, providing an upgraded extended latch charging handle and using quality internals like the NBS Black Nitride BCG paired with a Bear Creek 16″ Carbine Barrel.
