They are easily adjusted with simply removing the hardware from the forearm. Look inside and you will see the adjustment screw and the set screw to lock it down. Best way I have found to adj them is leave the wood off while setting it. As it wears in you may need to tighten it up. It does not have anyhting to do with the lock up of the action. It doesn`t take much turning of the adj screw to make a difference so go slow.
