Compact. Controlled. Loud enough to dominate the room. The TAGinn FBG-4 Sound Hand Grenade is the scaled-down sibling of the FBG-6, designed for tight quarters and realistic indoor training. With a smaller form factor and reduced decibel output, the FBG-4 gives MILSIM operators and airsoft trainers the shock effect they need—without overpowering enclosed spaces.
IMPORTANT: Only sold by the box—available in mission-ready bundles of 6 (one box), 12 (two boxes), or 24 (four boxes). No individual sales.
Each unit delivers a powerful bang with a 2-second delay, allowing for true-to-life breach-and-clear timing. Built for hostage rescue drills, force-on-force scenarios, and tactical room entries, the FBG-4 simulates real-world disorientation without projectiles or fragmentation.
