Yep,its a really special tool. Reach in your pocket and get a dime out and unscrew the screw in the forend.Remove the forend,and take a pencil or something and push the pin out that the barrel pivots on.You have to have the action open for this,and sometimes the pin is a very snug fit. A little jiggleing of the action and barrel helps get the pin out. Thats all there is to it,so take it apart and look all you want.. By the way,thats not a dumb question,you should hear some my wife asks.
