This model is well-suited for target shooters who appreciate the balance of a shorter barrel for maneuverability with the power of a full-size cartridge.

Feature Deep-Dive
The defining characteristic of the Adams Arms P2 is its patented short-stroke gas piston system. Unlike direct impingement designs that route gas directly into the receiver and bolt carrier, this system uses a piston rod that pushes the bolt carrier rearward. This reduces the amount of carbon and fouling deposited in the upper receiver, bolt, and chamber area. For the shooter who fires multiple rounds in a session, this means less cleaning time and more consistent operation as the rifle stays cleaner for longer. The system also runs cooler, which can improve reliability during extended strings of fire, especially in warmer conditions common to U.S. shooting ranges.
The 16-inch barrel is a practical length for a .308 rifle. It provides sufficient velocity for the cartridge to perform effectively on game out to several hundred yards, while keeping the overall length manageable for use in confined spaces or for transport. The 1:10 twist rate stabilizes common bullet weights from 147 to 175 grains, giving you flexibility in ammunition selection. The lightweight contour helps keep the rifle’s overall weight down, reducing fatigue during a day of hunting or a long range session. The barrel is button-rifled for consistent accuracy, and the muzzle is threaded (5/8×24) for attaching a suppressor or brake if your state allows.
The free-float M-Lok handguard is another practical feature. Because it does not contact the barrel at any point beyond the receiver, it allows the barrel to vibrate freely, which can improve inherent accuracy. The M-Lok slots provide multiple mounting points for accessories such as bipods, lights, or vertical grips without adding unnecessary weight or bulk. The handguard is slim enough for a comfortable grip, and the top rail integrates with the upper receiver for a continuous mounting surface for optics. This design allows you to configure the rifle to your specific needs without tools or adapters.
The short-frame lower receiver is a notable design choice. It reduces the overall height of the rifle, which can help with a more natural cheek weld when using optics. It also contributes to the rifle’s balanced feel, making it easier to carry and maneuver. The lower uses a standard AR-15 style pistol grip and trigger group, which means replacement parts and upgrades are widely available. The 6-position collapsible stock allows you to adjust length of pull for different shooters or for use with heavy clothing and body armor. The receiver is machined from 7075-T6 aluminum, a material known for its strength-to-weight ratio, and finished with a hard coat anodize that resists wear and corrosion.
The absence of iron sights is intentional. This rifle is designed for use with modern optics, and the flat-top receiver gives you the freedom to choose a red dot, low-power variable optic, or traditional scope. The Picatinny rail is machined to mil-spec dimensions, so optics mount securely and return to zero when removed and reinstalled. The bolt carrier group is nitride treated for smooth operation and corrosion resistance. The A2 flash hider reduces muzzle rise and helps conceal your position in low-light conditions, though it can be easily swapped for a different muzzle device.
Adams Arms has been manufacturing piston-driven rifles in the United States for over a decade, and the P2 represents a refinement of their design. The gas piston system is adjustable, allowing you to tune the rifle for suppressed or unsuppressed use, or for different ammunition loads. This adjustability is a practical feature for shooters who want to optimize reliability across a range of conditions. The rifle also includes a lifetime warranty on the gas piston system, reflecting the manufacturer’s confidence in the design.
Ideal Use Cases
- Hunting: The .308 Winchester is a proven cartridge for deer, hogs, black bear, and other medium to large game. The 16-inch barrel is maneuverable in brush or a tree stand, and the piston system reduces the chance of a malfunction in dusty or wet conditions.
- Target Shooting: The free-float handguard and consistent gas system support accuracy for range work. The rifle is well-suited for steel targets at 100 to 600 yards, and the ability to mount optics makes it easy to dial in for precision shooting.
- Home Defense: The compact overall length and light weight make this rifle easier to handle in a home environment compared to a longer-barreled hunting rifle. The .308 cartridge provides significant terminal performance, and the piston system ensures reliable cycling with defensive ammunition.
- Range Training: The low-maintenance piston system and durable construction make this a good choice for regular range use. The adjustable stock and M-Lok rail allow you to set up the rifle for drills and courses of fire.
Compatibility Notes
This rifle is chambered for .308 Winchester and will also safely fire 7.62x51mm NATO ammunition. It accepts standard AR-10 pattern magazines, including those from Magpul, Lancer, and DPMS. The barrel is threaded 5/8×24 for muzzle devices. The M-Lok handguard is compatible with all M-Lok accessories. The receiver uses AR-15 pattern pistol grips and trigger groups, though the buffer tube and spring are specific to the AR-10 platform. Holsters are not typically used for this platform, but soft cases and scabbards are widely available. Optics mount directly to the Picatinny rail with no additional adapter required.
