The Salty Old Gamer reviews the Master Mike airsoft grenade from Airsoft Innovations... "The successor to the often banned 40 Mike, we're having a close look at the Airsoft Innovations Master Mike.

If you've ever thought about adding the Master Mike to your airsoft arsenal, you don't want to miss this."
