Winchester Model 63

In 1919, the Model 1903 moniker was shortened to Model 03, and following a partial redesign in the 1930s, was renamed the Model 63. The Model 63 was first available for purchase in 1933 and remained in production until 1958. The Model 63  was chambered for the popular and widely available .22 Long Rifle cartridge. It was initially made with a 20" barrel, then with a 23" barrel from 1936 until the end of production in 1958. About 175,000 Model 63 rifles were manufactured, with the last 10,000 having grooved receiver tops for scope mounting.
