Quick Summary

The Remington Rolling Block action operates using a rotating breech block. After cocking the hammer, the block is held by a sear. Opening the block allows for loading, and a trigger pull releases the hammer to fire. The block then rotates down for spent casing extraction. This design, by Joseph Rider, was pivotal for early metallic cartridge firearms.
