Description

Magpul.
Gas Block.

The Adams Arms P1 AR-15 Complete Upper Assembly is chambered in 5.56x45mm NATO and is ready to fire right out of the box after installation onto any standard AR-15 lower receiver. The Adams Arms P1 Base Mid upper comes equipped with a 16" melonite-finished barrel, A2 flash hider, bolt carrier group, charging handle, picatinny rail gas block, delta ring assembly and Magpul MOE handguards. Additional features of the Adams Arms P1 include a forged A3 flat-top configuration that's ready to accept the shooter's choice of optic and/or rear iron sight, M4 feed ramps to help ensure reliable feeding and functioning during rapid strings of fire, and a mid length gas system for a smoother recoil impulse and longer sight radius.

Mil Spec.
Melonite Treatment.

The Adams Arms P1 AR-15 Complete Upper Assembly barrel has been finished inside and out with Adams Arms' proprietary QPQ Melonite treatment that bonds with the metal on a molecular level. 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, extending a barrel's service life by reducing the friction produced inside the bore upon firing for a net decrease in bore surface wear over time. Nitriding converts the Adams Arms P1 barrel steel's surface without any build-up, retaining all of the benefits of traditional chrome lining without suffering the accuracy degradation commonly encountered with it due to the uneven application of chrome inside the barrel's bore. The end result is a barrel that's capable of producing accuracy on par with a match stainless steel tube, while also exhibiting the longevity and resilience of a chrome lined, mil-spec barrel.

Gas Piston.

The P1 AR-15 Complete Upper Assembly features 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 an Adams Arms 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 Adams Arms P1 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 on the Adams Arms P1 are finished in QPQ Melonite for corrosion resistance and easy cleaning/maintenance. .
