Its true though... Every rifle really should have one.. even if it's the most basic of adjustment it would make the world of difference. I've always picked my scope/mount combo around the hight of the cheek piece.. it would be much easier to pick a scope then mounts & just adjust your stock to suit. Seems obvious to me..
Having said that we are seeing more & more rifles with this done to them from the factory but most are synthetic unfortunately.. ho hum..
