[cereal_killer]

i cant get my gat under 300 feet per second and i tried velocity and just got my tank turned low pressure. i dont know how to get into the lpr to remove shims and the field i play at has a max fps of 250 (indoor)

Do you have a LP tank?

[cereal_killer]

yea i bought a 68/3000 and they turned it lp for me

Weird... Are you sure? You might want to try a stock LP tank.

The shims are located on the LPR (right as you look at the front of thr gun) side. However, without a LPR gauge, you would only be guessing.

You would need to change the dwell as well.

thanks for all the help
