John Rigby & Co was founded in Dublin in 1775 and produced black-powder double rifles throughout the Victorian era before transitioning to nitro-powder cartridges. The Dublin Rifle in 577 black-powder caliber represents Rigby's pre-smokeless heritage, built with Damascus barrels and back-action or bar-action locks. These guns were used by Irish sportsmen and British colonial officers throughout the mid-Victorian period and are regulated as antiques in most jurisdictions.
