By bolt stick I assume you mean it's sticking back not forward?
Does it have the level 10 bolt?
Assuming that it does...
First thing to try would be to increase the velocity until it fires & then chrono it. If you can't get under 300 try putting a weaker spring on the bolt.
If that doesn't work you might want to try going to a bigger o-ring holder on the power tube if you can do so w/o it leaking.
