Some folks might consider this borderline foolishness, but I spent many, many hours as a boy plinking with a BB gun.  I saw the Marlin Cowboy BB gun at Academy Sports a couple of days ago and had to have one.  It's an attractive gun, but out of the box, the stock was a couple inches too short and made from some no-name, light colored wood from who knows where.  I had a chunk of Walnut that my brother sent me from the midwest, so I used it to make a new stock and foream.  The figuring of the walnut is very nice and certainly kicks the aesthetics of the airgun up a couple of notches.  Also more comfortable to shoot with the longer stock.
