If your mount comes with a blue bag (#6-48) and a red bag (#8-40) of screws, you have the proper screws for all year models. Please bear with us, you may receive an item with old packing cards. Previously our Mossberg 500 Pre '97 mount came drilled for and is provided with 6-48 screws and the late model of the mount (Post '97) came drilled for and provided with 8-40 screws. We have since updated our screw design for mounts requiring both sets of screws and we now provide both sets of screws with this one rail. Mossberg 935 (will require shortened screws)
