New Model Single-Six revolvers are the perfect small bore single-action revolver for plinking, small game hunting, or serious competition. The term New Model means that this model includes Ruger's transfer bar mechanism, which allows the weapon to fire only when the trigger has been pulled, meaning shooters can carry the revolver safely with all 6 chambers loaded. The durable and dependable Single-Six also comes equipped with fully adjustable rear target sights. The Convertible model comes with two six-round cylinders (one in .22 LR and one in .22 Magnum) for increased versatility. This single-action revolver's grips, metal, and bore are all in very good condition.
