Overview

The APS Thunder B CO₂ Sound Effect Simulation Grenade Core Set is a proven and widely used airsoft and paintball training device designed to deliver a powerful sound report without projectiles or explosive materials. Built as a low-impact CO₂ air burst system, the Thunder B is trusted by airsoft players, paintball teams, and training groups for its simplicity, reliability, and realistic distraction effect.

This Pull Ring grenade model operates like a traditional grenade, making it intuitive to use and ideal for immersive simulation environments.

How the Thunder B Works

The Thunder B core holds a standard 12g CO₂ cartridge inside a fully sealed compartment. When the pull pin is removed, the fire lever (spoon) snaps forward, puncturing the CO₂ cartridge. Pressure builds rapidly inside the attached disposable shell until it ruptures, producing a sharp, loud “pop” that simulates a grenade detonation.

There are no BBs, water, or fragments involved—the effect is purely auditory, making it suitable for controlled training and simulation when used properly.

Expandability & Replacement Options

The Thunder B Spare Core Set is perfect as a replacement or for players who want to keep multiple grenades prepped and ready. Having extra cores allows you to quickly swap shells and CO₂ cartridges without downtime between rounds.

APS offers a wide range of single-use disposable shells, including:

• Pineapple-style shells

• Sound flash tubes

Each shell is designed for one-time use and should be recycled after deployment. Replacement fire levers and pins are also available, with each fire lever rated for approximately 20+ uses.

Durability & Practical Use

Built with durability in mind, the Thunder B core is designed to withstand repeated use in demanding environments. When not loaded with a CO₂ cartridge, the Thunder B core also doubles as a decorative item or BB holder, making it a versatile addition to your kit.

Because the system avoids electronics, fuses, or pyrotechnics, it remains extremely reliable and easy to maintain.
