AMP Regulator Question

Hello everyone! I recently received my Wildcat MKII .25 cal rifle and it has the AMP regulator installed in it. I have been unable to find anything that describes which direction the hex screw increases or decreases the regulator pressure. Does anyone know which direction you need to turn the screw to increase power? I currently do not have a chrony to measure the velocity change nor do any of my friends (looks like one is in a near future purchase after I recover some from this purchase!)....any help would be greatly appreciated!

You absolutely can't tune properly without a chronograph. I would be more concerned with obtaining a chronograph than what turn of a screw does what, because the chronograph itself will tell you what that screw is doing when turned left or right. Just my 2 cents...



If it concerns you that much in the interim, then test which direction has least resistance, that direction will likely be increasing set point, and you can verify that by turning that direction some and keeping an eye on the gauge, if it raises then the assumption is correct, if not..take a shot or two and see if the pressure has dropped, and repeat.

Without a crony you are pissing in the wind. Leave it alone until you get one. Sure turn it but how do you get it back where it was? I'm guessing you are shooting pellets? If so they become unstable at high speed anyways. You could add a gauge to the bleed out screw hole to see what it doing. If you don't care and want to play with it zero your scope and set up a fresh target and turn the screw. If it hits high you found the higher pressure setting. BTW you can buy a crony for under a hundred bucks.



PS: Don't forget the hammer spring adjustment too. They need to work together to tune it efficiently.
