The Springfield Model 1922 is a .22 caliber bolt action rifle. It features a 24 inch (61 cm) barrel and a 5 round magazine. It was built as a training rifle, designed to mimic the M1903 Springfield rifle for training purposes. It was produced in several different versions until World War II, when shortages of materials made production of a training rifle impractical. The 1922M1 variant was introduced in 1925. This version had a new bolt head, an improved firing mechanism, modifications to the chambering, and a new rear sight. The stock was also modified to incorporate a flat based pistol grip.
