[0052] This is an invention made to equip PCP air rifles with capability to operate full automatically with the development made in our rifles having semi automatic working principle. One of the main components of the invention is the level lever (10) pressed by user to activate shifting from semi automatic to full automatic system or from full automatic system to semi automatic system for PCP air rifles. Mechanical operation structure changes with level lever (10) and thus PCP air rifle gains feature of both semi automatic and full automatic operation feature.

[0053] When the level lever (10) shown in FIG. 11 is in semi automatic position (FIG. 5), trigger tab stopper (11) part in upside down T form does not make any attempt to stop trigger tab (7) thanks to stopper spring (9). When rifle is fired, cock goes forward and then comes back and trigger tab (7) moves back and goes in front of semi automatic sheet (12), cock (6) is locked into trigger tab (7) again. Cock (6) is inserted into trigger tab (7) and motion forward is prevented and re-firing can not be made. When trigger (13) is released, semi automatic trigger sheet (12) goes above trigger tab (7) and becomes ready for firing. The motions are repeated and thus semi automatic operation is provided.

[0054] When level lever (10) is put in full automatic position, trigger tab stopper (11) part moves upward the connection housing in vertical rectangular form rounded on short edges. Thus trigger tab stopper (11) moves ahead of trigger tab (7). Whenever trigger (13) is pressed, cock (6) is released from trigger tab (7) and initiates firing. Thus trigger tab (7) leans on trigger tab stopper (11) part and is not released from semi automatic trigger sheet (12) and does not go into position to hold trigger cock (6). The cock (6) repeats firing motion.

[0055] For full automatic firing, the cock (6) is to run in harmony with sheet pusher (2) combining pellet pusher pin (3) and lever wedge (4). Unless pellet pusher (2) motion is completed, next firing should not be made by the cock (6). In order to solve this issue, the mechanism (1) is added full automatic tab (25) in form of plane without wings, which is shown in FIG. 12 and is one of main factors of our invention.

[0056] When the cock (6) returns, full automatic tab pusher shell (17) and full automatic tab pusher spring (16) having full automatic tab spring cover (15) goes upward from full automatic tab (25) tail (29) part. Thus full automatic tab (25) allowed to move by full automatic tab pusher pin (26) passing through hole in full automatic tab (25) body leaves the balance position and goes in front of wedge (27) located on nozzle (28) of full automatic tab (25) and thus holds the cock (6). Meanwhile, lever (5) connected onto lever wedge (4) goes back and takes front position and moves full automatic tab (25) downward from tail (29) and provides release of cock (6) wedge (27) from nozzle (28) of full automatic tab (25) and re-firing. This cycle continues synchronously until trigger (13) is re-released.

[0057] When cock (6) returns, the wedge (27) located on the cock (6) leans onto full automatic tab (25) nozzle (28) and holds the cock (6) by means of the wedge (27) and prevents front motion of the cock (6). Then the lever (5) connected to pellet pusher (2) by means of lever wedge (4) comes back and moves forward and moves full automatic tab (25) downward from the tail (29) and releases the cock (6). This mechanic operation continues until trigger (13) is released. Also during this operation, full automatic tab (25) and the parts located around and full automatic tab (25) are protected by full automatic tab housing cover (24) and their removal is prevented. In addition, trigger case (8) containing trigger (13), semi automatic trigger sheet (12), trigger tab (7), trigger tab stopper (11) therein is protected by means of closing trigger case cover (14)

[0058] In order to protect magazine against vibration occurring during firing, support part (20) is connected to magazine and lower part of magazine by support screw (18) as shown in FIG. 1. Magazine support part tab (19) is connected to lower part of magazine support part (20) in U shape by means of support pin (21). While motion is provided by help of level spring (22), level feature is provided by means of level ball (23). While magazine housing is empty, magazine support part tab (19) is protected thanks to foldable towards magazine housing as a result of such motion.
