Welcome to today’s Photo of the Day! This Springfield Armory trapdoor carbine represents the final evolution of America’s most famous single-shot military rifle. Arsenal-rebuilt during the 1890s with protective features added in 1890, this .45-70 carbine sports the distinctive “rear sight protector barrel band” and front sight cover that marked the end of the trapdoor era. No official “Model 1890” designation existed, but these rebuilt carbines packed practical improvements learned from two decades of frontier warfare. The 1890 modifications included both a rear sight protector barrel band and front sight cover designed to prevent damage during field use, especially when yanking rifles from saddle scabbards, where exposed sights constantly caught or broke.
The 1890-pattern front sight cover was tempered steel shaped roughly like an “8” with pin holes on either side, secured by a longer front sight pin that projected through both sides. Better than the earlier 1883 screw-secured covers that proved unreliable in field conditions. The timing makes this carbine historically significant. By 1890, Springfield Armory was already developing the bolt-action Krag-Jørgensen rifle that would replace the trapdoor design in 1892. These sight protectors were the Army’s final attempt to perfect a design that was already obsolete, adding practical improvements to weapons destined for replacement.
The trapdoor Springfield had served as the cavalry’s primary weapon throughout the Indian Wars, despite repeating rifles dominating civilian hands. These rebuilt carbines would see final service in the Spanish-American War before being retired for modern magazine-fed rifles. Soldiers appreciated the sight protectors. No more broken front sights from rough handling or bent rear sight leaves from careless scabbard work. The improvements came too late to matter, but they showed the Army had been paying attention to field complaints.
This carbine represents the end of an era—the last gasp of single-shot military rifles refined through hard-earned frontier experience. Two years later, the Krag made it all obsolete.
