Adams Arms P2 Pistol 5.56 NATO 7.5 in. Black 30 rd.

Description

The Adams Arms P2 Pistol 5.56 NATO 7.5 in. Black 30 rd. is a purpose-built AR pistol that pairs a proven piston system with a compact 7.5-inch barrel. Built around the P-Series Low Profile Adjustable Piston System, this pistol runs cleaner and cooler than direct-impingement guns. The 4150 Chrome Moly Vanadium Steel barrel is sealed in a QPQ Melonite/Black Nitride finish for long-term corrosion resistance. Flip-up sights, an ambidextrous safety selector, and an angled pistol grip come standard, making it ready to shoot right out of the box.

Key Features

• P-Series Low Profile Adjustable Piston System – WHY IT MATTERS: Reduces carbon buildup in the bolt carrier group, keeps the action running reliably even with suppressed fire, and cuts cleaning time in half.
• 4150 Chrome Moly Vanadium Steel Barrel with QPQ Melonite Finish – WHY IT MATTERS: This barrel steel handles high-pressure 5.56 loads without premature wear, and the nitride treatment penetrates the bore for a service life exceeding 20,000 rounds.
• Ergonomic Free Float Rail – WHY IT MATTERS: Covers the piston system while providing a slim, comfortable grip surface for off-hand shooting; allows accessory mounting without barrel interference.
• Manimal Flash Hider – WHY IT MATTERS: Reduces muzzle flash signature effectively in low-light conditions, keeping your sight picture clear during rapid fire.
• Ambidextrous Safety Selector & Charging Handle – WHY IT MATTERS: Left-handed shooters can manipulate the safety and charge the weapon without breaking their grip, making this pistol truly ambidextrous.

Who It’s For

This pistol suits the traditional shooter who wants the reliability of a piston-driven AR without the added weight of a full-length rifle. It’s a strong choice for home defense, truck gun, or range plinking where compact size matters. The adjustable piston lets you tune the gas system for different loads or suppressors, so it appeals to quality-conscious buyers who tinker with their gear.

Pros & Cons

• Pros: Clean-running piston system; ambidextrous controls; durable nitride barrel; adjustable gas for suppressed use; compact 7.5-inch barrel for maneuverability.
• Cons: The 7.5-inch barrel limits effective range compared to 10.5-inch or longer barrels; muzzle blast is noticeably louder than a 16-inch rifle.

FAQ

Is the Adams Arms P2 pistol legal to own with a 7.5-inch barrel?

Yes, under federal law, a pistol with a barrel shorter than 16 inches is legal as long as it has a pistol brace (not a stock) and is not designed to be fired from the shoulder. Check your state and local laws, as some states regulate AR pistols differently.

What ammunition does the P2 pistol cycle reliably?

Per Adams Arms specs, the P2 is designed for 5.56 NATO and .223 Remington. The adjustable piston allows tuning for different power levels, but it cycles best with standard-pressure 5.56 loads (55-62 grain). Low-velocity .223 may require gas adjustment.

Can I mount a suppressor on the 7.5-inch barrel?

Yes, the barrel is threaded 1/2×28 TPI and the Manimal flash hider can be removed for a direct-thread suppressor. The adjustable piston is a big plus here—you can dial back the gas to reduce over-gassing when running suppressed.

Does this pistol come with a pistol brace or just the buffer tube?

The P2 pistol ships with a buffer tube and an angled pistol grip. A brace is not included; you will need to purchase a compatible pistol brace separately if desired. Check current ATF rulings on brace use.
