ABSTRACT:
An interchangeable rib (40) for a rifle that is U-shaped and comprising an aiming plane (41) and two interfacing longitudinal fins (43), defining a channel (45) between them suitable for slidably receiving a band (60) equipped with shaped openings (62) inside of it, each of the shaped openings (62) being suitable for engaging a corresponding column (22) extending from a fixed base (20) to a barrel (10) of the rifle, the rib (40) being equipped with a slot (48) corresponding to an actuation hole (65) formed in the band (60) through which it is possible to actuate the sliding of the band (60) so as to take the edges of the shaped openings (62) to engage in grooves (23) realised along the columns (22) to prevent the detachment of the rib, the rib (40) also comprising, at at least one of its ends, a top lever seat (51) which is coupled with at least one top lever base (30, 31) correspondingly realised on the barrel to prevent the longitudinal sliding of the rib.
