The invention relates to a mechanism for the total absorption of the repulsion energy of fire arms meant to be mounted on fire arms which, during firing, produce the barrel displacement and also the displacement of those pieces attached to it. According to the invention, the mechanism comprises a horizontal clip, two vertical clips (2), two clips (5) with circular sector (5), a horizontal left clip (3), two of the right vertical back clips (4,6 and 8), central vertical and respectively horizontal, and one of the horizontal clips (9 and 10) for pushing and respectively for inclined pushing and a firing lever (11), hinged to one another by means of some hinging, oscillating, oscillating-rotating axes (13,14, 15, 16, 17 and 23). A cut (m) in the shape of circular arc is provided in the firing lever (11) wherethrough a fixed shaft (18) extends, said shaft being secured by nuts. Two threaded axes (19) are secured to the upper end of the lever (11) where two balance and extension springs (12) are hooked, the opposite ends of said two springs being in their turn secured to a threaded axis (20) ; two balance springs (7) located in a tilt position in respect to a vertical direction are attached to the oscillating-rotating axis (15).
