Description
The Adams Arms P2 Pistol is a compact, piston-driven AR pistol chambered in 5.56 NATO with a 7.5-inch barrel and 30-round capacity. The big thing that separates this one from a standard direct-impingement AR pistol is the Adams Arms P-Series adjustable piston system. Instead of dumping gas and carbon back into the action, the piston setup vents gas forward at the gas block, which helps the gun run cleaner and cuts down on some of the heat and fouling in the receiver.
This model uses a 4150 Chrome Moly Vanadium barrel with a QPQ Melonite / Black Nitride finish, so it is built with durability and corrosion resistance in mind. The 7.5-inch barrel keeps the gun short and easy to handle, especially for range use, vehicle storage, or anyone wanting a very compact AR-platform pistol. That said, 5.56 out of a barrel this short is going to be loud, bright, and will give up velocity compared to a 10.5, 11.5, or 16-inch gun. That is just the tradeoff with a short 5.56 pistol, and it is worth knowing before you buy.
The P2 also comes set up with practical features right out of the box, including an ergonomic free-float rail, flip-up sights, Manimal flash hider, ambidextrous safety selector, and ambidextrous charging handle. The free-float rail gives you room for optics, lights, or other accessories, and the ambi controls make it a little easier to run whether you are right- or left-handed.
If you are looking for a compact AR pistol that is a step above a basic budget build, the Adams Arms P2 is a solid option. You get a short, handy 5.56 platform with upgraded controls, a durable barrel finish, and the main selling point: Adams Arms’ piston-driven operating system.
