Alexander gives his take on TAGinn TAG-67 V2 Pyro Grenade for airsoft and milsim use in this Red Army Airsoft review. Based on the M67 frag grenade, this new generation pyro grenade has a 3.5 second delay after releasing the lever, allowing for a safe margin for the user to throw it. It uses a new pyro-element that will not kindle or ignite dry leaves and grass when it explodes.
