Key Features
- Piston-Driven System: Runs cleaner and cooler than direct impingement, reducing fouling in the receiver and enhancing reliability with suppressors.
- Versatile 300 Blackout Chambering: Effectively bridges the gap between 5.56mm and 7.62x39mm, offering superior terminal ballistics with subsonic or supersonic loads.
- 6-Position Collapsible Stock: Provides a customizable length of pull for shooters of all sizes and for use with body armor or heavy winter clothing.
- Durable QPQ Melonite/Black Nitride Finish: A salt-bath ferritic nitrocarburizing process that hardens the barrel and critical components for extreme wear resistance and protection.
- Mid-Length Gas System: Paired with the piston, this setup delivers a smooth, reliable recoil impulse ideal for fast follow-up shots.

The rifle’s 16-inch barrel with a 1:8 twist rate stabilizes a wide range of bullet weights, from light 110-grain supersonic rounds to heavy 220-grain subsonics. Weighing in at approximately 7.5 pounds unloaded, it strikes a solid balance between stability and maneuverability. The platform is mil-spec compatible, meaning it accepts a vast array of standard AR-15 parts and accessories—think Magpul grips, B5 Systems stocks, and a universe of optics and lights. Here’s the thing—when it comes to home defense or property patrol, the 300 Blackout’s performance in shorter barrels is legendary, and this 16-inch configuration gives you that authority with added velocity and a full legal profile. No gunsmithing required for most common accessory swaps, either.
Who This Rifle Is For
This Adams Arms P2 is built for the shooter who demands a workhorse with an edge. It’s for the Missouri hunter pursuing whitetail in dense timber where the 300 Blackout’s power shines. It’s for the defensively-minded individual who values the piston system’s consistent operation, especially when paired with a suppressor. It’s also for the pragmatic enthusiast who wants a single, robust rifle capable of handling multiple roles without compromise, from the range to the field. The investment of $1409.99 gets you into a premium-tier piston gun that’s ready for serious use.
Pros & Cons
Pros: The piston system offers exceptional reliability with less heat and carbon blowback into the action. The 300 Blackout caliber is immensely flexible, effective with or without a suppressor. The QPQ finish is arguably one of the toughest available for long-term durability. The rifle is drop-in ready for optics and lights on its full-length Picatinny rail.
Cons: Piston-driven ARs typically have a slightly different recoil feel and are marginally heavier than their DI counterparts. Ammunition for 300 Blackout is more expensive and less common than 5.56mm/.223. The initial cost is higher than a basic direct impingement rifle.
Frequently Asked Questions
Q: Is this rifle compatible with standard AR-15 magazines?
A: Yes. It feeds reliably from any standard .223/5.56 NATO AR-15 magazine, though dedicated 300 Blackout magazines are recommended to prevent accidental chambering of the wrong caliber.
Q: Can I shoot supersonic and subsonic ammunition without adjusting the gas system?
A: The Adams Arms piston system is designed to handle a wide range of pressures. It should cycle both types reliably, though as with any semi-auto, you may need to test specific subsonic loads to ensure 100% function, especially when unsuppressed.
Q: Is the barrel threaded for a muzzle device?
A: Yes, the barrel features standard 5/8×24 threading, ready for a flash hider, compensator, or direct-thread suppressor mount. The overall length with a pinned and welded muzzle device would be a consideration for other configurations, but this 16-inch model needs no such modification. This firearm is available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases.
