Hi, Millets rings didn't fit on mine ! Tried all kinds and finally gave up ! Had the rail D/T and attached a Ruger scope rail,added some ruger rings and topped it off with a BSA 6x24x40 with A/O . great pest and paper gun . And B4 I start getting flamed from some who don't like modifying surplus weapons , I bought this inexpensive .22lr to shoot not to display . Shoots fine too..............................WVleo
