Snapping Block

Snapping Block - A flat-faced lump of rather tough, but not dead-hard material, such as dense wood or horn, used against the standing breech of a break-open gun, after having dismounted the barrels, when pulling the trigger to release the tension on the mainspring. It absorbs the impact of hardened firing pin in order to avoid breakage, Such a device is not necessary when taking down a Beesley-actioned Purdey because when the barrels are opened, the mainspring tension is automatically released.
