The Auto-Loading Rifle
The auto-loading gun is not a new idea by any means, but it is only in recent years that it has been perfected, and as it is now made it is one of the finest, cleanest, quickest and easiest-firing guns on the market.
Look you now at the insert, and you will see a moving picture, nearly, of the action of a box magazine, auto-loading rifle from the moment of firing clear on through each operation until the new cartridge is slipped into the firing chamber.
In the picture shown at A the hammer has just struck the firing-pin and exploded the cartridge. As soon as the cartridge has been fired the recoil, which is instantly developed by the exploding gases of the powder, drives the breech-bolt to the rear, bringing the cartridge with it as well as the barrel extension, which is locked to it as shown at B.
This action compresses the heavy recoil and action spring in the butt stock, and which is shown fully compressed, the trigger being cocked in the cut B. Just as soon, though, as the recoil is spent the recoil spring draws the barrel forward, and this leaves a space for the empty shell to be ejected as shown at C.
When the extension barrel has gone forward to its natural position the spring carrier of the magazine pushes another cartridge into place, and at the same time the barrel presses on a catch which releases the breech-bolt and allows the recoil spring to drive the breech-bolt home, and so pushing the cartridge into the chamber. When the breech-bolt has completely closed the opening the gun is ready to fire again. In this way the untoward action of the recoil is made to do useful work.
