NBS 16" Carbine 5.56 NATO 1:7 Complete Upper
Only 3 left in stock
Who doesn’t like a nice quad rail This upper also features a 16″ NBS 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 as opposed to aluminum, providing an upgraded extended latch charging handle and using quality internals like the NBS Black Nitride BCG paired with a NBS 16″ Carbine Barrel.
