generally for most people.......if you are shooting exclusively prone, youll want to raise the buttpad uppward( to "lower" the rifle)......if you shoot exclusively offhand, youll want to drop the buttpad downward( to "raise" the rifle)......and if you shoot a mix youll want to leave it roughly in the middle..
the whole point of these stocks is to adjust them to fit us perfectly.......however theyll only fit perfectly in 1 position.....so keep that in mind when making adjustments.........if you are shooting PRS, youll need to get into a few positions and try it out.......ide reccomend for any adjustment you make, try it in the prone position, the kneeling position, and the standing position before you lock everything down....its not going to fit perfectly in every position, so youll need to compromise a little in all of them.
