Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

The 5.56 Tactical Evo 16" Upper is a standard mil-spec upper that incorporates the patented Adams Arms technology and the Samson Evolution extended free floating forearm.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. The free floating forearm ismanufactured by Samson Manufacturing and   extends along the sides and bottom of the gas block, giving you enough space to mount the removeable picatinny rail pieces to meet any of your needs.  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. Add the patented Adams Arms piston system and you'll have an upper that will run cleaner, cooler, and longer than any other AR upper you own.
