The Winchester Model 1903/63 is a semi-automatic rifle chambered in .22 LR. The model was originally named after the year it was introduced in 1903 and was one of the first commercially available semi-auto rifles produced by Winchester Arms. It was also introduced chambered in, the now obsolete, .22 Winchester Automatic, but it was given a redesign in 1933 so it could fire .22 LR. At that point it’s name was also changed to Model 63.
It uses an “Inertia Delayed Blowback” operating system, which is a convoluted way of saying blowback. The system works by inertia or the force vibrating through the gun traveling backward and when it hits on bolt, the force drives it back.
Features include iron sights, a wooden stock and a 10-round tubular magazine.
