is really great, but any paintball gun oil will work. You can pick up powertube o-rings
straight from AGD. If you're planning to keep the marker for a while, though, and if the o-rings haven't been changed recently, you should probably get a parts kit
and fully rebuild the marker. If one o-ring is starting to go, chances are that some others are on the verge too. So just change them all. Then it will be good to go for many, many years.
