Tired of light strikes or misfires on your M&P 15-22? The Volquartsen SureStrike Firing Pin will turn it back into the plinking machine you deserve. The SureStrike firing pin is CNC machined from S7 Tool Steel to withstand an unlimited amount of firing. It features a design with more material than factory to ensure hard-hitting performance. Volquartsen also adjusted the point of contact to cover more of the rim to help achieve positive ignition on every shot.
