<p>A mounting plate (4) for releasably mounting a sight (2) to a handheld firearm (3), said mounting plate (4) having a first side (4a) mountable to the sight (2), and a second side (4b) connectable to a support member (5), which support member (5) is attached to the handheld firearm (3) by means of a countersunk screw (13) arranged in a screw hole (10) formed in said support member (5), said second side (4b) of said mounting plate (4) being provided with a stud (7) configured to interact with a locking mechanism in said support member so as to releasably lock the stud to the support member in such a way that relative movement between said mounting plate (4) and said support member (5) in an axial direction of said stud (7) is prevented, wherein said mounting plate (4) further comprises a protrusion (7) on said second side (4b) of the mounting plate (4), said protrusion (7) being configured to be received within and engage with a portion of said screw hole (10) located between a surface of said support member and a head (13a) of said countersunk screw (13) when said mounting plate (4) is locked to the support member (5), so as to prevent relative rotation between the mounting plate (4) and the support member (5) about a longitudinal axis of said stud (7). The arrangement prevents misalignment of the sight. Furthermore, as the protrusions are received in the existing screw holes, the mounting plate may be used with already commercially available support members, such as the QR-system® from Leupold®, without modifying the support member.</p> |
