M1E10 Garand-Ljungman Prototype

Springfield Armory was involved in experimenting with he M1 Garand throughout its production, looking at various different elements that could be improved. A series of experimental models were made, with M1E[x] designations. Some of these went on to become production models like the M1C and M1D snipers, while others simply proved that some idea were not feasible. One of these failed experimental models was the M1E10, made in 1944.

The M1 Garand was a rather complex gun to manufacture, and Springfield was aways interested in ways to simplify it. The operating rod in particular was a tricky part to make, with its slight but very high-tolerance bend. After acquiring an AG42 Ljungman rifle from Sweden, Springfield decided to try adapting the Ljungman gas system to the M1. By using a gas tube to redirect gas back about 6 inches before venting onto the gas piston, the hope was to eliminate the bent section of operating rod. Instead though, testing concluded that the venting hot gasses caused more problems inside the stock than the manufacturing improvements would have justified.

Thanks to the Springfield Armory National Historic Site for giving me access to this truly unique specimen from their reference collection to film for you! Don’t miss the chance to visit the museum there if you have a day free in Springfield, Massachusetts:
