You should be able to do it , with no sweat !
It came with shims , right ? So , first you have to measure your LOP , mount the gun with your ( fingers first joint ) on
the center of the trigger , bring the gun up to your cheek tight ( do-not lower your head on the stock ) like I said , bring the
gun ( up to your cheek ) , now have someone measure the distance between your nose and thumb ( should be 1" to 1 1/2" )
subtract the difference , from you measuring in a straight line from the center of the trigger to the center of the recoil pad
as the gun is laying flat on the table . That would be your LOP and you will cut the stock to accomplish that length , don't
forget the thickness of the recoil pad ?
The shims are forgiving , whether you are a right or left handed shooter , look at the directions , as to Cast-on for left
or Cast-off for right handers but , the most important is comb height , make sure , with cheek down tight you're looking down
the center of the rib ( you can check this looking in the mirror ) your pupil will be inline with the bead or beads . Making more
comfortable , there should be a shim to cast the stock , more to your liking ?
Take your time and make it shoot where you're looking , and that is , with a hard focus on the lead-edge of the target !
Have fun.......other than that.......try your State forum for a fitter in your area .
