Airsoft Innovations - Tornado Grenades and Distraction Device Kit

Airsoft Innovations - Tornado Grenade have been out in the market for a while and there are already a few good reviews on them. Rather then regurgitate those reviews please click on 1 of my favorites, made by the SCAAR guys in Austria:

Pros

• Reusable.
• Few external parts to lose.
• Consistent bb delivery.
• Can use higher pressure gasses.

• Gas pressure based timer is ambient temperature sensitive
• Bottom cap can be cross threaded if not carefully screwed on

Airsoft Innovations - Tornado Grenades and Distraction Device Kit

I recently purchased the AI Distraction Device Kit. This turns your bb hurling Tornado grenade into a LOUD sound distraction device. It's very simple to install and is a completely reversible process. It is also ambient temperature dependent so if the weather is cold, it may not have enough force to burst the mylar "popper" stickers.
