I've got a 582 I'm working on. Birch stock, I removed the finish, special walnut stain and Tung oil finish. While I was at it I made a sort of Schnabel for end on the stock. I think it looks good, but looks to be mahogany now instead of birch. I free floated the barrel, so I'm working on getting a second screw in front of the trigger assy, right where that tiny screw is in the middle of the floor plate on the 581, the 582 that screw is there but the plate ends there and it's got a lug under the barrel. Mine shoots good enough for a light 22, I don't know if what I'm doing will help it, but right now it will hold 3/4" or better with good ammo at 50yd. I've got a cheap enough Bushnell 3-9 on it.
