F-1 Durabolt Ttz 5.56 Nato Silver

The F-1 Durabolt Ttz 5.56 NATO Silver is a precision-engineered bolt carrier group designed specifically for AR-15 platforms operating in 5.56mm NATO. This product is ideal for law enforcement, military personnel, and serious rifle operators who require components capable of sustained high-round-count operations.

Constructed from Carpenter 158 steel for the bolt and 8620 steel for the carrier body, this bolt carrier group is built for durability and reliability. The CRN (Chrome Nitride) coating in a silver finish enhances corrosion resistance and reduces fouling, ensuring compatibility with standard MIL-SPEC receivers and associated AR-15 components.

Weighing 0.81 pounds, the F-1 Durabolt Ttz integrates seamlessly into existing M16/M4-pattern builds without adding significant mass. It is particularly beneficial for operators conducting extended training sessions or duty applications requiring sustained fire capability, where component durability is essential.
