This Barreled Upper is permanently treated with RF85, a nano-technology that injects calcium into the molecular fabric of the metal. RF85 is permanent. It is IN the metal. RF85 reduces friction 85% and wears with the metal. Under heat and pressure, the calcium nano particles elongate and form a protective barrier that eliminates the need for lubrication.
Long story short, RF85 technology delivers 85% less friction, 23% faster action, and the ability to clean your rifle with soap and water. RF85 is proven effective in the medical industry, in automotive and racing, and now, firearms. Once you understand just how effective this process is, you won't settle for anything less than an Anderson NO-LUBE Rifle.
Upper includes the bolt carrier group and charging handle, so it's complete and ready to go.
