Description

The 5.56 Midlength Base 16″ Upper is a standard mil-spec upper that incorporates the patented Adams Arms technology and the m4 style handguards. The midlength piston system will give you the benefits of a longer forearm by giving the user a longer, more ergonomic grip, a longer sight radius between the front and the rear sight for quicker sight acquisition and less felt recoil. The piston system parts and the barrel have been treated with our salt nitride Meloniting process making them harder and more corrosive resistant than hard chrome. With the patented Adams Arms piston system, you’ll have an upper that will run cleaner, cooler, and longer than any other AR upper you own.

** This upper is NOT eligible for free bag and magazine promotion **
