This product is designed for law enforcement, military personnel, and serious shooters who require dependable performance in demanding conditions.
Constructed from mil-spec materials, the bolt is made from 9310 steel, a chromium-molybdenum-nickel alloy known for its strength and impact resistance. It undergoes heat treatment and shot peening to enhance its surface properties, while the carrier is fabricated from durable 8620 hardened steel. Each component features a black-nitride finish that provides superior corrosion resistance and low-friction operation.
This bolt carrier group is compatible with 5.56x45mm NATO, 300 AAC Blackout, and .223 Remington chamberings, making it a versatile choice for shooters who utilize multiple upper receivers or plan caliber conversions. It is particularly beneficial for operators using patrol rifles, duty weapons, or precision trainer builds where reliability and material longevity are critical.
