The Single Six has been with us for over 60 years now, and continues to be a highly popular plinking, trail and small game gun. Story offers conversion cylinders to increase the potency of these fine little firearms. These 8-round cylinders are machined out of 1144 steel and are hot blued. The cylinder will drop into most 6-shot Single Six New Models, but fitting may be required in some instances. Major gunsmithing, such as hand replacement, should not be required.
