A5 won't reach proper velocity
I've got a buddy's Tippmann A5 that was a bit beat up and needed a bit of TLC. After breaking it down and cleaning 3 years of grime out of everything, replacing some missing pins, all of the orings, and the missing velocity screw, the marker refused to chrono over 225-230. After subsequently replacing the rear spring, the marker's highest reading I could get over the chrono was 240.
The only thing I noticed out of the ordinary was that I did not locktite the velocity screw in and it turned really easily- more easily than I've ever seen on an A5- I'm wondering if this may have something to do with it and it needs a new powertube? I didn't notice any cracks or anything, just the really loose velocity screw.
