Acoustic Cap Grenade ШТР-5 (STR-5) – Brown

A new era of airsoft destruction is here. Forget about fragile plastics and constant worries about where your grenade will land. Introducing the FlashStrike ШТР-5 (ŠTR-5) – an uncompromising evolution of our legendary sound grenade, completely redesigned ground-up for the toughest CQB fights and military simulations (MilSim).

While the previous generation relied on a plastic body with a rubberized sleeve, this model features a revolutionary all-rubber body that pushes durability boundaries to extreme levels. The result? Maximum mechanical durability achieved thanks to up to 600% thicker rubber walls compared to older models. Throw it on concrete, slam it against a wall, or accidentally step on it in heavy boots – this beast can handle it all.

The heart and armor of the new ШТР-5 model is a massive all-rubber construction. It dampens impacts, absorbs vibrations on landing, and protects the internal firing mechanism. No more cracks after hard impacts on asphalt or stones. With this reusable throwable sound grenade, you are simply buying reliability that will back you up in every game.

Our cap sound grenade ŠTRAJK 5 operates on the principle of a mechanical firing pin and standard 8-shot toy caps (8" caps).
Upon impact on a hard surface, the grenade immediately emits a sharp bang / sound effect accompanied by a light flash and smoke. Perfect for simulating an explosion without using real pyrotechnics!

• 
  Safe for CQB: Subject to organizer approval, this cap grenade can also be used in arenas and indoor fields where standard pyrotechnics are strictly forbidden. As a mechanical acoustic grenade, it is not dangerously loud or hazardous, yet it creates massive psychological pressure and reliably clears out rooms.
• Extremely Low Running Costs: Forget single-use or expensive gas-powered grenades. Here, you just replace the cap ring, reset the pin, and get right back into action. A single shot costs literally a few pennies.
