Who wants to Tune my QB-78???

[SDale]

I've got a box stock (other than a muzzle brake) QB-78 from Archer just waiting for a tune. I don't have the time or energy to screw with the springs, valve etc. right now.

It's a .177 and I'm lookin to Hot Rod it. I don't care too much about shot count as long as I can get  20 out of the 2 CO2 cartriges. I'm getting about 45-50 or so before she starts slowing down.

So who's up for the challenge???
