The Heritage Mfg 331000203 is a replacement cylinder chambered in .22 WMR (Winchester Magnum Rimfire), purpose-built for shooters who need to swap calibers on their Heritage revolver. This blued steel cylinder holds six rounds and gives you the flexibility to transition between .22 WMR and compatible Heritage revolver platforms without swapping the entire gun. Whether you're plinking, small-game hunting, or want to run cheaper practice rounds, having a dedicated cylinder on hand is practical and cost-effective.

Built from blued steel, this cylinder delivers the durability you'd expect from a Heritage part—no fancy coatings, just honest construction designed to handle regular use. The .22 WMR cartridge packs more velocity and energy than standard .22 LR, making it a solid choice for varmint work or small-game applications where that extra performance matters.

This is a factory replacement component, so fitment and function are engineered to spec. If you own a Heritage revolver and want the versatility of running .22 WMR or simply need a spare cylinder, this six-round unit is the straightforward answer.
