T ERMINOLOGY AND D ESCRIPTIONS
Descriptions in this booklet generally refer to the
gun in the horizontal position. That is, in the nor-
mal firing position. For example, the muzzle is for-
ward or front; the butt stock is rearward or rear; the
trigger is downward or underneath; the sights are
upward or on top. Figure 1 covers the general fea-
tures and benefits of the Model 63 design.
For general parts terminology, refer to Figure 2A.
For breech bolt and bolt slide terminology refer to
figures 2B and 2C.
The Winchester Model 63 is also shown disassem-

G ENERAL D ESCRIPTION
The Model 63 is a semiautomatic rifle that allows
the shooter to fill the magazine and shoot consecu-
tive rounds — taking loaded rounds from the tubular
magazine to the chamber automatically — until the
magazine is empty. After each cartridge fires, the
action automatically ejects the empty cartridge out
the ejection port to the right. The action is operated
manually using a cocking system mounted on the
forearm tip. The rod protruding from the tip is called
the operating sleeve. Pushing it fully in (rearward)
opens the action: extracting and ejecting any car-
tridge in the chamber and loading a cartridge (if pre-
sent) from the magazine into the chamber.
The action itself uses a blowback design, where the
firing of the cartridge actually begins the rearward
motion of the bolt. Inertia completes the bolt’s
motion rearward, cycling the action. The magazine
is loaded through a port in the right side of the butt-
