QB79 valve ?

[bd249]

How does the valve come out of the QB79? Is it the same as the QB78? Do I take off the CO2 mount block? I am doing the tuning myself.
Just need a little help and any ideas in tuning  I had a ball handle in my tool box that is now my new oversize bolt handle.
I would like to get to about 800 fps  and also like to make it a little more quite  most of my shooting is in the back yard  I have access
to a machine shop to do mods.

Yes, valve come out the same. The higher you squeeze out of the QB..the louder it gets and uses more co2. Try here for info on what you need to do >> http://www.gatewaytoairguns.org/GTA/index.php?action=library
