  • Information
Designed by David Tubb, the legendary highpower shooter. The body of this firing pin is aluminum and the tip itself is steel. The result is a product that decreases lock time in the Remington 700 by roughly 40%. A must for the competitive shooter and a significant upgrade for the varmint shooter. Gunsmith installation is recommended.
