Pedersen Selfloading Rifle

When the US military decided to seriously look at replacing the 1903 Springfield with a semiautomatic service rifle, two designers showed themselves to have the potential to design an effective and practical rifle. One was John Garand, and the other was John Pedersen. Pedersen was an experienced and well-respected gun designer, with previous work including the WWI “Pedersen Device“ that converted a 1903 into a pistol-caliber semiauto carbine and the Remington Model 51 pistol, among others.

Among the major reasons why was that his toggle action was
