The Faxon FF76239 Bolt Carrier Group delivers enhanced reliability and extended service life for 7.62x39 AR platforms. This precision-engineered BCG features premium 9310 steel construction with advanced nitride coating for superior corrosion resistance and reduced friction.
What Makes This Different
Faxon's Type 1 bolt carrier group stands apart from standard offerings through its use of 9310 steel rather than typical Carpenter 158 steel. The nitride coating penetrates the steel surface rather than simply coating it, creating a harder, more durable finish that maintains lubricity even under extreme conditions. This results in smoother cycling and reduced wear on critical components compared to phosphate or chrome-lined alternatives.Key Features
