cocker velocity problems

[neonbob]

anyone had this problem with their cocker?

after i air it up and shizzle. my velocity is terrible. its around 100 fps, but will increase about 50 fps with every shot, untill it reaches its max [i usually keep it at about 250-275. it will stay there the rest of the day as long as i dont remove my air. i dont know why it does this.

i have a 01 cocker with the bomb 3 way, upgraded ram, no upgraded internals or bolt. put in the roller sear, and i have a vigilante reg. could that be it?

That sounds very similar to a classical problem associated with Mags and uniregs, which isn't suprising since the Vigi is another AA reg. Lube the piston seat and the other seals within the reg, preferably with Gold Cup or Cobra Snake Oil. That should fix it entirely.
