An affordable pistol upper assembly without cutting corners. This means using a nitrided steel gas block from an American Manufacturer as opposed to aluminum and quality American Made handguards, paired with a 7.5″ Nitride treated barrel chambered in 5.56 NATO. This also means taking the time to ensure that the upper will function reliably. We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the properly torqued barrel nut and muzzle device.

Looking for a short pistol upper with effective medium range ballistics? A 10.5" Hardened Arms 5.56 upper is one of the most popular configurations we make. The 10.5 inch barrel allows you to keep a carbine gas system which means a smoother running pistol over a 7.5" build. The extra length of the barrel also keeps the muzzle velocity around 2650fps for effective energy on target at medium range. Built with our 4150CMV nitrogen stress relieved barrel blanks these uppers are designed to last a lifetime. What's in your go bag?
