This is a high quality black walnut stock 1906 Expert pistol grip .22 Winchester rifle. It is not over sized and the original 1890, 1906 plastic buttplate will fit on it! This stock will not fit a strait grip receiver!! (If the two metal tangs that come off of your receiver-that the tang screw goes through to hold the stock on- are parallel, then you have a strait grip. If the bottom tang curves down, away from the top tang--then it is a pistol grip. All stocks are shiped priority!
