In the realm of AR-15 rifles, few components are as critical to performance and reliability as the bolt carrier group. This offering stands among the elite, forged by top-tier domestic Mil-Spec contractors known for their precision and durability. At its core is a 5.56 AR rifle bolt that serves as the foundation for renowned custom rifles.
The bolt itself is crafted from Carpenter 158 steel, undergoing shot peening to enhance strength—a testament to meticulous engineering. It features a tool steel extractor and ejector, each paired with an appropriate extractor spring, ensuring flawless ejection under high pressure conditions typical of military specifications.
The extractor boasts construction from 4140 gun-quality steel—annealed and cold drawn per Mil-Spec standards—delivering unmatched resilience in demanding environments. Complementing this robust assembly is an externally parkerized and internally chrome-lined 8620 steel carrier. The gas key adheres strictly to proper machining protocols: it’s chrome lined, phosphated, heat treated following GI specifications, secured with Grade 8 fasteners, and meticulously staked during final inspection within their shop.
This precise attention to detail in machining ensures long-term functionality of your AR's gas system while maintaining unwavering reliability—a quality every seasoned shooter respects in their equipment. For those who understand the value of preparedness on the range or field, having a spare complete bolt carrier assembly at hand epitomizes readiness.
