3. The semi automatic and fully automatic operation system of claim 1, wherein the trigger tab has a connection housing horizontally oriented within the trigger tab and the connection housing has a rectangular shape wherein the four inside corners are rounded.

4. The semi automatic and fully automatic operation system of claim 1, wherein the projecting end has a downward slope relative to the tail.

5. A device, comprising: a U shaped magazine support; a magazine support tab, pivotally connected to a lower part of an opening of the U shaped magazine support using a support pin; a level spring located in a level spring housing; and a level ball positioned on top of the level spring.

6. The device of claim 5, wherein the level spring and the level ball are located in between the U shaped magazine support and the magazine support tab.

(18) This is an invention made to equip PCP air rifles with capability to operate fully 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 fully automatic system or from fully 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 fully automatic operation feature.

(19) 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 (6) 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.

(20) When level lever (10) is put in fully automatic position, trigger tab stopper (11) part moves upward by means of the connection housing (11A) which has 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.

(21) For fully 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 fully automatic tab (25) in form of plane without wings, which is shown in FIG. 12.

(22) When the cock (6) returns, fully automatic tab pusher shell (17) and fully automatic tab pusher spring (16) having fully automatic tab spring cover (15) goes upward from fully automatic tab (25) tail (29) part. Thus fully automatic tab (25) allowed to move by fully automatic tab pusher pin (26) passing through hole in fully automatic tab (25) body leaves the balance position and goes in front of wedge (27) located on projecting end (28) of fully 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 fully automatic tab (25) downward from tail (29) and provides release of cock (6) wedge (27) from projecting end (28) of fully automatic tab (25) and re-firing. This cycle continues synchronously until trigger (13) is re-released.

(23) When cock (6) returns, the wedge (27) located on the cock (6) leans onto fully automatic tab (25) projecting end (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 fully 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, fully automatic tab (25) and the parts located around and fully automatic tab (25) are protected by fully 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) In order to protect magazine against vibration occurring during firing, magazine support (20) is connected to magazine and lower part of magazine by support screw (18) as shown in FIG. 1. Magazine support tab (19) is connected to lower part of magazine support (20) in U shape by means of support pin (21). The magazine support tab (19) is pivotally connected to a lower part of the U shaped opening (20B) of the magazine support (20).

(24) 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 tab (19) is protected thanks to foldable towards magazine housing as a result of such motion.
