This Adams Arms P2 Mid-length Gas Piston Upper Assembly is chambered in 5.56x45mm NATO and comes ready to fire right out of the box after installation onto any standard AR-15 lower receiver.  The P2 features a melonite finished, 14.5" government contour barrel with a 1 in 7" twist, making it capable of stabilizing medium- to heavy-weight projectiles of up to 77 grains. The pinned and welded Manimal flash hider brings the barrel length up to 16 inches and features slim diameter that allows the user to remove and replace the gas block without removal of the flash hider itself. The P2 configuration comes equipped with a free floating, Adams Arms M-LOK handguard. The low profile P-series Micro gas block is 40% lighter than previous railed versions and fits nicely under the rail. Together, the forged A3 flat-top upper and handguard create a long, uninterrupted top rail interface with ample room for mounting optics and/or iron sights.


The upper's 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 barrel 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. 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.

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.
