And Rear Detail Of Magazine

This drawing shows all details of the weapon in closed position with all parts at rest except magazine spring which is under compression.

In the drawing an empty cartridge case is shown in the firing chamber. In actual operating conditions, this could not happen except at the instant of discharge. When this weapon is discharged, the barrel and breechblock recoil together and the empty cartridge case is ejected.

The barrel (A- at all points) and its rear barrel extension are forged from a single unit. The breechblock travels in the barrel extension. The front sight is also part of the barrel forging. Note that while there is a heavy recoil spring positioned around the firing pin, the firing pin itself has a small spring at its forward end within the heavier recoil spring which serves to withdraw the point of the firing pin from the primer of the fired cartridge as the weapon recoils. This prevents firing pin breakage. The locking block (8) is rising through the cut in the underside of the barrel extension to engage in its notches in the breechblock (2).

The detail view shows the construction of the magazine and its follower. As the cartridges are stripped down in the magazine through the top of the action, the shape of the follower forces the first cartridge to the right and zigzags each succeeding cartridge. Lips at the top of the magazine well prevent the cartridges from coming out accidentally.

To unload this weapon, it is necessary to move the breechblock back and forward once for each cartridge, which must be inserted in the chamber and ejected; or as an alternative method, the bottom of the magazine may be removed to permit withdrawal of the floor plate, magazine spring, follower and cartridges.
