Abstract: A safety apparatus for a grenade launcher assembly which provides a dual-way ammunition feed, recognizes the direction automatically without the importance of which direction the user opens the handle in order to prevent the direction selector or movement from reversing and which does not permit opening to the other unselected side for the filling-off phase.

Abstract: The invention relates to a semi-automatic firearm comprising a hand stock nut (1), bracket (6), piston (7), magazine tube plug (8), magazine tube (9), gas tube (10), mechanism (11), lock bolt (12), body (13), lock (14); bolt arm (15), hand stock (16), barrel cap (17) and barrel (18). In order to enable the use of cartridges with different loads and to reduce the recoil, said firearm comprises a valve piston (5) connected with the piston (7) between the gas tube (10) and magazine tube (9) and the hand stock nut (1). Depending on the pressure generated by the cartridge the valve piston (5) is able to release excess gas through discharge holes (20).

Abstract: The present invention relates to lock mechanisms, in which the trigger (2) in the trigger group (12) comprising a safety lock (6) is contacted with the hammer (3) through a contact point (11) so that the respective gun is prevented from firing as a result of the hammer (3) being released by the trigger (2) under jolting effect, said lock mechanism being characterized by comprising at least one trigger lock (1), in addition to said safety lock (6), said trigger lock (1) being contacted by at least one swinging point (9) formed on the trigger group (12) in order to prevent the trigger (2) from releasing the hammer (3) under jolting effect by setting into motion with a certain force from said swinging point (9).

Abstract: A piston element, which has a piston element made of a single piece, one of the important parts of a gas operated shotgun enabling the shotgun to operate, and the piston rings assembled into the slots on the piston element. At least one female part connects with at least one male part, forming the piston element, in order to provide the piston element to be formed by screwing two parts to each other and positioning the piston ring between the same, and at least one sealing member positioned between the male and the female part.
