Product Description

Arcturus RS Thunder A CO2 Sound Simulation Grenade Core
Features:
- Reusable CO2 grenade core that powers Arcturus's Thunder A shells for realistic tactical sound effects on the field
- Runs on a standard 12g CO2 canister; drop in a fresh cartridge and you're ready to go again in seconds, no single-use waste
- Cross-compatible with Thunder A, Thunder B, and Thunder V shells, so it slots into the same shell ecosystem used across some of the market's most popular CO2 sound grenades, so you're not locked to one brand's shells
- Fast ≤2 second fuse delivers a realistic, near-instant bang once the pin is pulled, built for genuine surprise rather than a slow countdown
- Manufacturer explicitly advises against "cooking" the core (holding it after the pin is pulled to shorten the throw-to-bang window) — pull and throw only
- Core only — shells and CO2 cartridges are sold separately, so you can build out exactly the shell/core combo your loadout needs
- Part of the Arcturus RS line, Arcturus Tactical's performance parts and accessories range
