Adams Arms P2 Pistol 5.56 NATO 7.5 in. Black

About this product

What is the Adams Arms P2 Pistol? The Adams Arms P2 Pistol is a 5.56 NATO AR-platform pistol built around a 7.5-inch barrel and piston-driven operation for compact, high-reliability performance in close-quarters scenarios. This isn't your typical direct-impingement AR—it's a purpose-built short-barreled firearm designed for shooters who understand the tradeoffs of running a rifle cartridge in a pistol configuration. At 10.85 pounds unloaded, it's heavier than most AR pistols but delivers mechanical advantages that justify the weight for certain applications.

What is the Adams Arms P2 Pistol used for?

The P2 is designed for close-quarters defensive use and tactical training where full-size rifles are impractical. Its 7.5-inch barrel and piston system make it ideal for vehicle-based operations or confined spaces where maneuverability matters more than long-range accuracy. The ambidextrous controls and free-float rail allow for rapid accessory mounting—I'd recommend pairing it with a compact red dot and weapon light for low-light scenarios.

How does the Adams Arms P2 Pistol compare to the Stevens 334 Rifle?

The P2 delivers faster handling and higher magazine capacity than the Stevens 334 Rifle in .308 Win, but sacrifices ballistic performance and effective range. Where the Stevens 334 achieves sub-MOA accuracy at 200 yards with its 20-inch barrel, the P2's 7.5-inch barrel limits effective engagement to under 100 yards due to significant velocity drop—approximately 2,400 fps versus 3,200 fps from a 16-inch barrel. The P2's 30-round capacity and semi-auto operation provide superior rapid engagement capability compared to the bolt-action Stevens' 4-round internal magazine.

What does it weigh and what are the dimensions?

The P2 weighs 10.85 pounds empty and measures 22.5 inches in overall length with the stock fully collapsed. Its 7.5-inch barrel contributes to a compact profile while the 12-inch free-float rail provides ample real estate for grips, lights, and lasers. The weight distribution feels forward-heavy compared to direct-impingement AR pistols like the Daniel Defense DDM4 PDW, but this improves muzzle control during rapid strings of fire.

Who is this NOT for?

This pistol isn't for beginners or budget-conscious shooters who aren't prepared for the NFA paperwork and tax stamp requirements. The 7.5-inch barrel produces 165 decibels of muzzle blast—louder than most shooting ranges allow without double hearing protection—and the $932.99 price tag doesn't include the inevitable $200 tax stamp or trust fees. If you're looking for a simple range toy without regulatory complications, consider a Stevens 555 Sporting shotgun instead.

What's in the box?

You'll receive the complete pistol with Magpul MBUS flip-up sights pre-installed, one 30-round PMAG, the Manimal flash hider, and all necessary paperwork for Form 1 submission. Adams Arms includes their proprietary armorer's tool for piston adjustment—a $45 value if purchased separately—and the entire package ships in a hard-sided case with foam cutouts sized specifically for the 22.5-inch overall length.

Is the Adams Arms P2 Pistol worth it at $932.99?

At $932.99, the P2 justifies its price through premium materials and the included piston system that typically adds $300 to comparable AR builds. The 4150 CMV steel barrel with QPQ Melonite finish will outlast nitrided barrels by approximately 5,000 rounds under sustained fire, and the ambidextrous controls are machined from 6061 aluminum rather than molded polymer. For shooters who need reliability in a compact package and understand the NFA process, this represents solid value compared to building a similar pistol from aftermarket parts.
