Barrel Construction and Nitride Treatment
The 10.5-inch M4 profile barrel is made of durable 4150 Chrome Moly Vanadium steel, a proven material choice for strength and durability in compact barrel configurations. The M4 profile provides a balanced weight distribution suitable for shorter barrels, maintaining structural integrity while managing heat during rapid-fire sequences. The nitride treatment enhances surface hardness and provides enhanced longevity through superior corrosion resistance, ensuring consistent performance across extended shooting sessions and varied environmental conditions. The 1:8 twist rate supports a variety of bullet weights, accommodating ammunition from lightweight 55-grain bullets for high-velocity applications to heavier 77-grain match projectiles. This provides versatility in ammunition selection, supporting diverse shooting applications engineered for precision and reliability.
A2 Upper Receiver and Gas System Design
The A2 upper receiver is crafted from 7075-T6 aluminum with anodized finish, offering exceptional strength-to-weight ratio and durability for demanding tactical use. The anodized finish provides enhanced corrosion resistance while maintaining the classic military styling that has defined the AR-15 platform since its military adoption. The A2 upper features the traditional forward assist and spent case deflector, providing full military-spec functionality. The carbine-length gas system with front sight base (FSB) is ideal for smooth cycling and optimized performance, delivering consistent extraction and ejection in compact configurations. The stainless steel carbine-length gas tube offers excellent corrosion resistance and durability, supporting dependable gas operation. The FSB serves dual purposes—functioning as both the gas block and providing a standard military-spec iron sight.
Bolt Carrier Group and Charging Handle
The included reliable bolt carrier group is made from 9310 and 8620 alloy steels with nitride finish, materials selected for their exceptional strength and durability under the high-pressure cycling demands of the AR-15 platform. The 9310 steel is commonly used for bolt construction due to its superior fatigue resistance, while 8620 alloy steel provides excellent wear characteristics for the carrier body. The nitride finish enhances surface hardness and corrosion resistance, reducing friction for smoother operation while supporting reliable long-term performance. Paired with a standard A2 charging handle, the complete upper ensures easy manipulations and dependable operation with classic design that has proven reliable over decades of military use.
