The 12" Samson Evolution Handguard is a free float design to maintain accuracy. The included handstop and picatinny rail sections allow the rail to be customized for additional accessories, if desired, or left off for a sleek and lightweight competition gun. The Ultra Lite barrel offers match grade accuracy without adding any unnecessary weight. The Diamondhead flip up sights are set at a 45 degree angle. Push the button and the spring loaded sights snap into a 1 O'clock position, allowing the shooter to roll the weapon counter clockwise and quickly engage close targets. When not in use, the sights fold flat to stay out of the way.
All Adams Arms uppers feature a short stroke gas piston operating system, which prevents hot gas and debris from being directed back into the action upon firing. The result is a rifle that runs cooler, cleaner and more reliably than those utilizing a standard direct gas impingement system of operation. To ensure that damage doesn't occur to the buffer tube from carrier tilt, the bolt carrier is equipped with enlarged "skis" to help guide it into the receiver extension. The bolt carrier's solid steel, 1-piece construction incorporates an integral piston strike face to guarantee integrity over time, while the bolt assembly is spring loaded for proper lock-up and to help reduce bolt bounce and cam pin wear. All piston components are finished in QPQ Melonite for corrosion resistance and easy cleaning/maintenance.
