Falcon,

It looks like your Staghorn and my Cascade Magnum have essentially the same design. I understood everything that you wrote except one part. When you say "action channel" are you refering to the section where the trigger drops down? There is a small ledge on the stock at the very rear end of the action - there is a screw there. Is this the part you are referring to? Otherwise, I all seems pretty clear. Thanks for the advice and the pic!
