The Ruger Single-Six Convertible is a classic single-action revolver built for shooters who want a versatile rimfire companion, with a 4.62" cold hammer-forged blued alloy steel barrel, 6-round cylinder and an extra cylinder to switch quickly between .22 LR and .22 WMR for economical range work or higher-velocity small-game hunting. The Model 0623 carries Rugers patented transfer bar safety and loading gate interlock to reduce the risk of accidental discharge while maintaining the traditional exposed hammer and crisp single-action trigger feel, and its windage- and elevation-adjustable rear sight paired with a ramp front sight and 1:14" RH twist delivers pointable, repeatable accuracy. At 32 oz and 10.25" overall length with black checkered hard rubber grips, it balances for target practice, plinking, youth training, or carrying afield. As part of the long-running Single-Six series, this revolver blends rugged materials, reliable function, and convertible caliber capability; FFL transfer required.
