The Valken Tactical Thunder B Small Multi-Grenade Package Starter Kit
Everything you need, besides CO2 cartridges, to get started. Includes one single main Core kit + 3 Cylinder Multi-style Shells (C, B, and Pineapple grenades). The core unit is reusable and compatible with all types of Thunder V shells and Thunder B (Hakkotsu). The Thunder V emits a loud 'boom' sound of 130DB 3-5 seconds after releasing its safety pin. No pyrotechnics involved, as it's only co2 powered. The outer cylinder shell will need to be replaced after each use. Easy to use and install. Read instructions first. Replacement parts, pins, etc are all available at for purchase.
