The barrel undergoes a durable Black Nitride finish, a treatment that enhances surface hardness, reduces friction, and provides an additional layer of protection against wear and environmental elements, ensuring the barrel maintains its integrity and precision over thousands of rounds.

Further complementing this, the barrel also incorporates double-lapping and a chrome-lined interior, crafted from robust chrome moly vanadium steel. This combination provides a remarkably smooth bore, minimizing bullet deformation and maximizing consistency, while the chrome lining significantly extends barrel life and eases cleaning, particularly important in a high-volume precision rifle. The rifle-length gas system, paired with the barrel, ensures optimal pressure regulation for smooth cycling and reduced felt recoil.

Why is a 1:10" twist rate optimal for .308 Win?

The 1:10" right-hand twist rate is a carefully chosen specification for the .308 Winchester cartridge. This rate provides the ideal spin for a wide range of popular .308 bullet weights, typically from 150-grain to 180-grain, ensuring maximum gyroscopic stability for projectiles. Stable bullets fly truer, reducing environmental influences like wind drift and leading to tighter groups downrange. This makes the SuperSASS Gen II particularly adept at maintaining precision across varying ammunition types, a crucial factor for both competitive shooters and hunters.

The muzzle of the SuperSASS Gen II is fitted with an ArmaLite Tactical Brake. This precision-engineered muzzle device is highly effective at mitigating felt recoil and muzzle rise, allowing the shooter to maintain a clear sight picture through the recoil impulse. This rapid follow-up shot capability is invaluable in dynamic shooting scenarios or during long strings of fire where fatigue must be minimized. The combination of an expertly crafted barrel and an efficient muzzle brake ensures that the SuperSASS Gen II consistently delivers its rounds with remarkable precision, making it a reliable tool for achieving sub-MOA groups.

Ergonomics and User Interface: Designed for the Shooter’s Comfort and Control

A rifle's ergonomics play a pivotal role in a shooter's ability to maximize its accuracy potential. The ArmaLite AR-10 SuperSASS Gen II excels in this regard, featuring components specifically chosen for their adjustability, comfort, and control.

Magpul PRS Gen2 Stock: The Ultimate in Precision Adjustability

The rifle is equipped with the renowned Magpul PRS (Precision Rifle/Sniper) Gen2 stock. This stock is a hallmark of ergonomic excellence, offering a full range of adjustments for the length of pull and comb height. This extensive adjustability allows every shooter to customize the rifle precisely to their body mechanics, ensuring optimal eye relief with mounted optics and a consistent, comfortable cheek weld.

• Length of Pull (LOP) Adjustment: Allows the shooter to fine-tune the distance from the trigger to the buttpad, ensuring a natural and consistent shooting posture.
• Comb Height Adjustment: Critical for aligning the shooter’s eye perfectly with the centerline of the scope, eliminating parallax errors and promoting precise aiming.
• Recoil Absorption: The robust design and rubber butt-pad of the PRS Gen2 stock also contribute to effective recoil absorption, enhancing shooter comfort during extended shooting sessions and aiding in faster target reacquisition.
