Black Winter Airsoft reviews the TAGinn Reaper launchable projectiles for airsoft and milsim use. These come in two versions, the 3.5 which has a 3.5-second delay, and the 2.5, which of course has a 5-second delay. These are compatible with the TAG-ML36 launcher and these should be used with eye protection and other precautions as required in your area as these are pyros.
