Power mod - Adjustable. Return to Airguns
The power setting mod is designed to be used when the gun is being
The power can be set to the desired level - in this case 11.5 ft lbs
then the action assembled into the stock - no field adjustment is
possible without completely removing the action from the stock
and using tools etc.
This is a design I came up with though I am very sure this is not
original ! it is just the logical way to alter the hammer spring
The reason for this mod is that I found if I stripped the gun and
rebuilt it the power would change every time - slightly different
position for the TP seal etc. it was really getting frustrating so
it occurred to me a way of setting the power after the main parts
had been built may be useful.
I have this system on two of my guns, this is the Mk1 - Mk2 is made
from stainless steel
