air leak coming out of the velocity adjuster....

[brutus106]

its coming out of the velocity adjuster in the back of the gun/ valve (were you stick the allen wrench)

how do i fix it?

[MindJob]

If you have the heavy spring in the LVL10, go down one.. if not

....replace the piston in the reg.

i have stock bolt and reg/valve, replace the piston? like buy a new one?

What velocity are you shooting? If you crank the velocity adjuster down too far, it will vent air out the back like it is doing. Try backing it off a little. If that doesn't work, then yes, you will have to replace the piston.

im having the same problem it wont shoot over 220 with venting out the back of the marker. do i need to replace the piston and if so how much is that going to cost?

I am assuming that you have a classic valve. If so, here is a link.

It costs $15 from AGD.

If you have a retro valve you will need this one.

That one is $20 from AGD.
