Designed to restore life to dried out seals in Airsoft GBB and NBB pistol magazines, 40mm grenades and other gas devices. Stocked and used by our Patrol Base workshop and other staff members for years. Each can has 270ml contents and can restore magazines over and over. 

Please note this is not a guaranteed item to repair leaky magazines, but so far we have been impressed with its success rate. We have used this in store many times and repaired many magazines with slow leak.
