Have you seen the Airsoft Innovations Tornado Airsoft Grenade in action yet?
This has got to be the best airsoft grenade on the market right now. It’s fully reusable, can take quite a beating, fires 200 BBs at once in full 3D spread, is powered by any gas (propane/green gas, or canned air/HFC-134a), and can clear out a room very effectively! It can also be reconfigured as a Distraction Device, which produces a loud bang instead of firing BBs, to distract people as you enter the room and take them out.
Not to mention that in the next month AI is releasing a mod for this grenade that will allow you to set amazing traps. When you trigger the trap, say with a tripwire, it will launch the grenade 5 feet into the air and then it will go off mid-air. Imagine the scenarios …
