If your rifle has a swivel stud, give it a little Picatinny love with Weaver's new Swivel Stud Picatinny Rail Adaptor. This small section of Picatinny rail attaches to a rifle's swivel to provide a place for any Picatinny style rail mounted accessories. Constructed of 6061 T6 aluminum with a matte Type 3 hard coat anodized finish, the Swivel Stud Picatinny Rail Adaptor includes steel mounting hardware and a side mounted swivel stud that still allows the use of a sling.
