APS Thunder B M18 CO2-Powered Airsoft Sound Grenade Set (including 3 Piece Replacement Shell)
Need a distraction that turns heads and clears corners? The APS Thunder B M18 CO2-Powered Sound Grenade delivers a sharp, loud bang without the risks of pyros—making it a top pick for serious airsoft players. Designed to mimic the iconic M18 smoke grenade, this non-lethal noise-maker uses a reusable CO2 core to trigger a loud rupture when the internal pressure builds, simulating the chaos of a flashbang without the fire hazard. Perfect for CQB environments, Milsim events, or just spicing up your gameplay.
What’s great is the simple reset process. You get three HDPE 2 plastic shells included—tough enough for the blast but recyclable for eco-conscious disposal. After each bang, just swap out the used shell, load a fresh 12g CO2 cartridge (sold separately), and you’re back in action. The mechanism uses a real-style pin and spoon system, giving you that immersive, tactical feel. Lightweight, field-friendly, and surprisingly affordable to run, the Thunder B is ideal for adding some realistic shock-and-awe to your loadout. Just make sure you warn your team—this thing’s not subtle.
