The Single-Six Convertible design allows quick switching between .22 LR and .22 WMR using separate cylinders; the .22 WMR cylinder is rollmarked with the caliber and Ruger logo, while the .22 LR cylinder is typically unmarked. The revolver is presently set up with the .22 WMR cylinder installed, clearly rollmarked with the caliber and Ruger logo. Capacity is 6 rounds.
Construction features a stainless-steel frame, barrel, and cylinder, with a satin stainless finish for a clean, uniform look. Hardwood grips with Ruger medallions provide a traditional feel and solid purchase.
The 5.5 inch barrel pairs with a 1:14 RH twist to stabilize a wide range of rimfire loads. Overall length is 11 inches, delivering a full-size profile that balances well for field or range use.
Iron sights include a ramped front blade and a fully adjustable rear for windage and elevation, allowing precise zeroing with different rimfire ammunition. The action is single-action, true to the Single-Six lineage.
Safety features include Ruger’s transfer-bar safety system and a loading-gate interlock. This example corresponds to the catalog KNR-5 designation with manufacturer part number 0625 and dates to the 1980 era.
