This invention relates to “high-power pneumatic weapon system”. It is the weapon shooting by means of compressed air, having double pistons engaged each other, fore-sight with multiple adjustments and rotatable around its own axis, and mechanism for releasing excessive air, of which the trigger tightens up after shooting.

1. A high-power pneumatic weapon system comprising: an upper body (1);a rear sight coupled to a top portion of the upper body (1);a barrel (71) housed in upper body (1);a lower body (3);a joint pin (45) axially coupled with said upper body (1) and said lower body (3);a piston group (4) coupled with

1. A high-power pneumatic weapon system comprising: an upper body (1);a rear sight coupled to a top portion of the upper body (1);a barrel (71) housed in upper body (1);a lower body (3);a joint pin (45) axially coupled with said upper body (1) and said lower body (3);a piston group (4) coupled with said lower body (3) wherein said piston group is configured to compress air during both opening and closing of said upper body and said lower body wherein said piston group comprises: a piston rod shaft (5) coupled with said piston group (4) wherein said piston rod shaft (5) is coupled with said upper body (1);a large piston compression section (6) within said piston group (4);a small piston (12) within said piston group (4);a small piston compression section (7) having an air inlet hole (8);a small piston shaft (10) having an opening between an outer diameter of said small piston shaft and an inner diameter of small piston pipe (11);a check valve comprising a check valve spring (55), check valve pin (54) and check valve o-ring (56) coupled to one another and with said small piston compression section (7);an air compression compartment (46) coupled with said small piston compression section (7) via said check valve;wherein said air compression compartment (46) is configured to hold air from a one or more pumpings each defined by one opening and closing of the upper body with respect to the lower body that compress air into the air compression compartment (46);wherein during opening of said upper body (1) from said lower body (3) about said joint pin, through application of an opening force, said piston group (4) starts to extend and air begins to compress inside said large piston compression section (6) and is stored in said small piston compression section (7) after passing through said air inlet hole (8) and wherein a distance between said small piston (12) and said small piston shaft (10) increases;wherein during the closing of upper body (1) with lower body (3) about said joint pin, through application of a closing force, air inside the small piston compression section (7) overcomes the force of check valve spring (55) and pushes the check valve pin (54) and check valve o-ring (56), so that air is compressed into the air compression compartment (46), wherein the air compression process continues until pressure between small piston compression section (7) and air compression compartment (46) is equalized and check valve pin (54) and check valve o-ring (56) return back to their original positions due to the force of check valve spring (55), and wherein an air seal is provided by check valve o-ring (56); and,a discrete value multiple height fore-sight (76) attached to the upper body (1) via a fore-sight pin (77) wherein said discrete value multiple height fore-sight is configured to rotate about a horizontal axis defined as an axis that is orthogonal to a longest dimension of the barrel and rotate in a vertical plane that passes through the discrete value multiple height fore-sight, rear sight and wherein the discrete value multiple height fore-sight remains fixed at a desired discrete position by centering of a fore-sight ball and by a force of a fore-sight spring (79) wherein said discrete value multiple height fore-sight is rotatable to a plurality of discrete heights that each correspond to a particular number of pumpings so that the rear sight does not require adjustment based on the number of pumpings when shooting at a given distance from a target. 2. The high-power pneumatic weapon system of claim 1 further comprising a relief nozzle (48), relief gasket (49), relief piston (50), relief spring (51) and relief adjusting screw (53) coupled to one another and to said lower body (3);wherein excessive air compressed in said air compression compartment (46) as a result of the one or more of pumpings performed by opening and closing of upper body (1) onto lower body (3), which is determined relief adjusting screw (53) which sets the shooting power, passes through relief nozzle (48) and pushes the relief gasket (49) and the relief spring (51), wherein the relief piston (50) is connected, and after passing through relief adjusting screw (53) and relief spring (51), it is released to outer environment. 3. The high-power pneumatic weapon system of claim 1 further comprising a valve buffer (66) located between valve rod knob (65) and hammer (21), that protects said valve rod knob (65) and said hammer (21) from deformation. 4. The high-power pneumatic weapon system of claim 1 further comprising an output nut (69) carrying barrel o-ring (70) and valve o-ring (68) that are replaceable.
