Shield Arms Sa-Roc-442-Rmsc Roc S&W 442 Rmsc
The Shield Arms R.O.C. mounting system brings modern optics to your Smith & Wesson J-frame revolver without permanent modifications. This S&W 442 RMSc mount lets you install a compact red dot sight—like the Shield RMSc or Holosun K Series—on a J-frame revolver using a reversible, non-invasive system. If you carry a 442 or similar J-frame, you get faster target acquisition and improved accuracy at any distance, all while keeping the option to remove the mount and return your revolver to factory condition.
The R.O.C. (Revolver Optic Carrier) uses precision engineering to solve a problem that has traditionally required gunsmiths: mounting an optic on a revolver frame. The conversion bracket and side spacers are machined from aerospace-grade 7075-T6 aluminum and finished with Type II anodizing to handle everyday carry wear and corrosion. Installation is straightforward—no drilling, milling, or gunsmithing—and everything you need (bracket, spacers, and hardware) comes in the box.
Built in the USA with a lifetime warranty, this mount is designed specifically for S&W shrouded hammer or hammerless J-frame revolvers to guarantee fit and function. It's also holster-compatible with the Phlster City Special, so you can carry your optics-equipped revolver in your normal rig. Whether you're testing the concealed-carry potential of a red dot on a J-frame or upgrading your defensive setup, the Shield Arms R.O.C. 442 RMSc keeps your options open.
