Valken's Thunder V flashbang style airsoft grenades are one of the most recent styles to be released to the airsoft market. By harnessing the power of a 12g CO2 cartridge in a reusable spoon style grenade core, these timed airsoft grenades detonate with a wall-shaking 130 decible boom that makes most players running for cover. The Cylinder C is essentially the successor to the classic Cylinder B but with reusable top and bottom caps to reinforce the shell for a louder bang and prevents shell cracking on impact. The caps easily screw on or off and can be recovered from spent shells for use with future grenades. This set includes a Core and 12 Cylinder C style shells.
