The First Trapdoor Springfield Carbine, Model 1870
This video delves into the first production carbine model of the Trapdoor Springfield, the Model 1870. It highlights key features differentiating it from prototypes, such as its short receiver, 21 3/4" barrel, sling ring, and absence of serial numbers. The description also notes its unique narrow rear sight slider and its position as the final .50-70 caliber Trapdoor, soon to be replaced by the .45-70 cartridge in the 1873 model, with improvements focused on the receiver and breech block arc. Only 362 of these carbines were produced.
