A sight mount for fire arms comprises a base part ( 10 ) to be mounted on a fire arm, and an upper part ( 11 ) to have a sight mounted thereon. The upper part is pivoted relative to the base part for movement about an axis between a first position corresponding to the operative position of the sight, wherein a projection ( 33 ) on the, upper part or the base part engages a groove ( 29 ) on the other part, and a second position transverse to the first position, wherein the projection is disengaged from the groove to allow the upper part to be separated from the base part. A latch ( 21 ) is spring biased to an engaged position preventing pivoting of the upper part, and against the spring bias can be brought into a disengaged position allowing pivoting of the upper part.
