Prototype Tube-Magazine Trapdoor Springfield
This video explores a rare prototype Trapdoor Springfield rifle modified with an under-barrel tubular magazine, likely for the 1882 US Army repeating rifle trials. The design, possibly by Augustine Sheridan Jones, features a Kropatschek-style lifter and a manual magazine cutoff. Ultimately, the modification proved impractical due to an extra manual step required for chambering rounds, making it less efficient than contemporary bolt-action repeaters.
