We go to another ICS Airsoft Class, a series of howto videos in maintaining airsoft products from ICS. For this episode it is replacing the O-Rings from their 40mm lightweight grenade. It will be a lot of O-Rings to replace and before doing that they recommend that you purchase the ICS MA-408 O-Ring Pack which has the complete O-Ring Set.
