Essential .308 Firing Pin Retaining Pin for AR-10 & LR-308 – Luth-AR 308-BT16

The Luth-AR 308-BT16 .308 Firing Pin Retaining Pin is a critical small component designed to secure the firing pin inside the bolt of .308 Winchester and 7.62x51 NATO AR-10 style rifles. This standard retaining pin, also commonly referred to as a firing pin cotter pin or firing pin retaining pin, prevents the firing pin from moving too far rearward while allowing it to travel freely during the firing cycle. Manufactured by Luth-AR, a trusted American company specializing in high-quality AR platform components, the 308-BT16 offers precise fitment and reliable performance for both DPMS-pattern and compatible LR-308 bolt carrier groups.

Without a properly fitting retaining pin, the firing pin can become misaligned or fall out during disassembly, leading to malfunctions or safety concerns. The Luth-AR 308-BT16 is precision machined to the correct dimensions to ensure secure retention while maintaining smooth firing pin movement.
