Troubleshooting

Safety BB missing (Troubleshooting)
It can be replaced by a small stainless steel “BB” broken off from the Dog Tag Chain.

Safety BB spring (Troubleshooting)
It can be replaced by a part of the tank O-ring that is cut into to the same length as the spring.

Break balls (Troubleshooting)
Polishing the Barrel and replace the Bolt will fix it.

Some PGP2001 users have the ball breaking problem caused by the design of the newer bolt, here are some modifications you can do to avoid this problem. See Six’s Page for more details. Also Cooper-T had made a aftermarket bolt for the newer model can easily take care of this problem as well.

12-gram not being pierced (Troubleshooting)
The piercing pin might be damaged or wore out, get a replacement.

I’ve had people come in to my field a few times with either consistently low velocity or non-piercing problems on the 2k, and I’ve found that 90% of the time it’s because they have taken their gun apart and not screwed the RVA assembly  in far enough again.  Usually another half turn or sometimes full turn brings the velocity up to where it should be, and puts enough spring tension behind the pin to pop the 12 gram. – swcblues

Properly due to a weak main spring or the velocity adjuster being backed out to far. – Lee

Gun not able to be cocked (Troubleshooting)
The RVA assembly is in incorrect position, DO NOT screw the RVA assembly all the way in, it should be in somewhere in the middle on the threading, pay attention its position before you take it out.

How to fix it: Loosen the screws on the grip frame. Back the entire RVA assembly ( Not just the screw) out a full turn or two, so that it sits a little further back. Put he grip frame back on. Then adjust the velocity screw (allen screw) to bring the velocity to where needed.

All shots are low-powdered (Troubleshooting)
The piercing pin might be damaged or wore out, get a replacement.

Leaking down barrel (Troubleshooting)

First, you may have a jammed or broken valve spring. If it doesn’t push the valve pin closed, it’ll leak like a pig…. Next, you may have some dirt on the cupseal or even a damaged cupseal. The worst thing I can think of would be the valve pin being bent. If one of the previously stated problems caused it to seize in its bore, the thing could be tweaked. You’re best bet is to pull it apart and root around for the problem….. drop me a line if you need assistance.

Why is the first shot of a new 12-gram so slow? (Troubleshooting)
Unlike most 12 gram powered guns, the Sheridans do NOT pierce the cartridge when you screw down the front cap. The piercing pin is actually on the cup seal, and pierces the 12-gram when the hammer drives it forward on the first shot. That’s why the first shot is always low powered. You can turn the gun upside down and cock it without loading a paintball so you don’t waste one with that first shot, or there are a couple of modifications that you could do. Ask the custom shops for more details.
