Precision Crafted Bolt Carrier Group for AR-15/M4 Rifles
For those who seek reliability and precision in their AR-15 or M4 platforms, this bolt carrier group stands as a testament to meticulous engineering and robust construction. Designed with mil-spec dimensions, it ensures seamless compatibility with your rifle.
The heart of this assembly is the case-hardened 8620 steel bolt carrier, finished in black nitride for enhanced durability and corrosion resistance. This finish not only provides a sleek appearance but also contributes to smoother operation under demanding conditions.
A critical component, the gas key is crafted from 4130 steel and secured using Grade 8 hardware. It is properly staked into a specially milled "valley" to guarantee steadfast positioning during use. The hardened 4340 cam pin further underscores the commitment to longevity and performance.
The firing pin meets military specifications, constructed from 8740 steel that has been center-less ground and hard chrome coated for optimal resilience against wear over time. Meanwhile, the bolt itself adheres strictly to true mil-spec dimensions; its external surfaces are precisely CNC ground from case-hardened 9310 steel.
This exceptional attention to detail extends to every part of the bolt assembly: all components share the same durable black nitride finish. The extractor follows suit with Mil-Spec standards using high-grade 4340 steel paired with an efficient spring and O-ring combination for reliable extraction every time you pull the trigger.
