would that fit on a prostock

[yuik]

idk my fatty doesnt fit on my cocker its a nightkast, it isnt able to screw in all the way. we somewhat fixed this problem by putting a extra oring in the asa so it had a tight fit.

The adjustment screw on all of our regs is 3/8"-24 threads.
Yes, it will fit on a ProStock.
It will fit the nightKast too, though you may have to take the frame off to install it.
The reg does not need to be tightened into the ASA.
It will not feel loose when it is aired up.
