Hakkotsu Thunder B Shocker Pin Set

The Hakkotsu Thunder B cotter pin set includes 12 replacement cotter pins designed for use with Thunder B Shocker sound grenades.

Thunder B Shocker sound grenades are popular with airsoft enthusiasts, among others. They produce a loud bang or explosion sound to simulate the effect of a grenade exploding. The pins are necessary to activate the grenade, and are pulled out when used. If the pin wears out or is lost, this set of 12 pins allows the Thunder B Shocker sound grenades to maintain full functionality.
