Need RT Help!

[DyNasTy]

Hey guys, I am teching a marker for a team mate. It is a original Automag RT.

I replaced every external and internal o-ring I could find, but it wont stop leaking! Its weird, It actually shoots air out of the back of the valve. and when I pull the trigger it holds it back and when i let go it does it again.. its like its shooting the air backwards... can anyone help me!?

Turn down the velocity.

Use a 1/8" allen key and give it a 1/2 turn counterclowckwise.

Yeah it's probably that the reg in the valve is overpressurized and it's venting excess pressure. The reason that the triggrer is staying back is that the valve pin is too long/ short. Make sure it's just behind the trigger with a little gap. If it is too lumg/short remove the gripframe and take out the whole sear assembly and twist the pin.
