The Model 1870 Trapdoor Carbine represents a rare and significant step in US military firearm evolution, being the only Trapdoor carbine produced in .50 caliber before the shift to .45-70. Its design incorporated mechanical improvements over the 1868 model, such as a wider breech block opening angle, and featured distinct carbine elements like a side-mounted sling bar instead of swivels. With only 362 units manufactured, its extreme rarity makes it a highly prized collector's item for enthusiasts of early breech-loading firearms.

This video examines an experimental .30-40 Krag chambered Trapdoor Springfield, a reproduction used as a baseline in 1890s US Army magazine rifle trials. Despite its appearance, it featured unique sights and a smaller bore. While surprisingly accurate, the Trapdoor action proved unreliable with high-pressure smokeless loads, leading to its limited adoption.
