This Adams Arms Tactical EVO Carbine Gas Piston Upper Assembly is chambered in 5.56x45mm NATO and is ready to install onto any standard AR-15 Pistol or Registered SBR lower receiver. The Tactical EVO line represents an excellent value and is the result of blending characteristics from Adams Arms' EVO Ultra Lite and Tactical Elite Uppers with the goal of producing a new high performance, versatile platform at a more economical price. It features a Melonite Finished, 11.5" M4 Contour Barrel with a 1 in 7" Twist, making it capable of stabilizing medium- to heavy-weight projectiles of up to 77 grains. This Tactical EVO comes equipped with a 10" ExtendedSamson Evolution Modular Free Floating Handguard that surrounds the Picatinny Rail Piston Gas Block and creating an uninterrupted top rail surface that runs from the rear of the flat-top upper receiver to the end of the gas block for mounting optics and/or iron sights. The upper comes complete with bolt carrier group, charging handle, A2 flash hider, and two removable modular rail sections (one 2" and one 4").

The unique Melonite treatment applied to Adams Arms' Barrels surface-hardens the metal, extending barrel service life by reducing friction in the bore and lessening bore surface wear. Also referred to as Salt Bath Nitriding, this treatment produces an extremely hard, slick surface on steel that resists carbon adhesion and increases corrosion resistance, making for easier cleaning and maintenance. Nitriding converts the steel's surface without any build-up, retaining all of the benefits of traditional chrome lining without suffering the accuracy degradation commonly encountered due to uneven application of chrome inside the barrel's bore.

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, and the bolt assembly is spring loaded for proper lock-up and to help reduce bolt bounce and cam pin wear.
