A Superlight with sights and adult stock, unless it's old stock is gonna be hard to find since they don't make it that way any more apparently. The current production Superlight Compact(Youth) is the only configuration in a complete 243 rifle that has sights. The model number for the current and old production adult stocked 243 Superlight is SB2-SL5 which comes with a scope base only now, I looked at the 2006 catalog, it was listed with scope rail only then. Even more frustrating is the 243 Superlight barrel is being discontinued in the accessory barrel program, following suit, it will be discontinued as a complete rifle, unfortunately.
