I was wondering if anyone knows where to find the thingy that you use to fill one scuba tank from another. My buddy who sold me my Marauder said that this was a good way to keep one tank full while the other one was in the shop getting filled. Also, has anyone done much homework regarding the most accurate pellet for Marauders? I know each gun is different, but I would imagine that there has to some pellets that would be better overall. Thanks for your help, the gophers will hate you.
