The TacFire MAR120308 hard chrome steel firing pin for .308 Win AR platform rifles is a straightforward, reliable replacement part for shooters who need a dependable ignition component. Built from hard chrome steel, this firing pin is designed to handle the demands of centerfire rifle shooting—whether you're running suppressed rounds at the range, working through match ammunition, or putting rounds downrange for hunting. It's the kind of part you install and forget about, which is exactly what you want from critical components.
AR-platform shooters in .308 Winchester know that keeping your bolt carrier group in top shape matters. A quality firing pin is part of that equation. The hard chrome steel construction resists corrosion and wear, holding up to repeated firing cycles without degradation. If you're rebuilding a bolt carrier group, swapping out worn parts, or just keeping spares on hand, this is a no-fuss option that fits the .308 AR platform.
This firing pin is purpose-built for the AR-10 style platform in .308 caliber. Installation is straightforward for anyone comfortable working on their own rifle, and it's sized specifically for .308 chambered systems—not a universal part, not a compromise.
