The separate convex sections of the inner tube are arranged to fit into the separate concave support sections in the outer tube, wherein the end section of the inner tube is pivotally received within the end section of the outer tube. ## Claims ### Claim 1 A reflex sight comprising: an elongated sight housing comprising an outer tube and an inner tube defining a light channel with an optical axis, wherein the inner tube is pivotally secured within a front end or a back end of the outer tube allowing adjustment of the longitudinal axis of the inner tube in a vertical and/or horizontal direction; a lens with a partially reflective surface arranged in a front end of the inner tube facing an intended target; a light source arranged in the light channel, which is adapted to emit light towards the reflective surface projecting a reticle for a user of the sight; characterized in that: the outer tube terminates in an end section forming an inner perimeter section of the outer tube, which is provided with concave indentations forming separate concave support sections; the inner tube has an end section forming an outer perimeter section, which is provided with separate convex sections; wherein the separate convex sections of the inner tube are arranged to fit into the separate concave support sections in the outer tube, wherein the end section of the inner tube is pivotally received within the end section of the outer tube. ### Claim 2 (depends on 1) The reflex sight of claim 1, wherein the separate concave support sections form at least portions of spherical caps in the inner perimeter section of the outer tube; and the separate convex sections form at least portions of spherical caps on the outer perimeter section of the inner tube. ### Claim 3 (depends on 1) The reflex sight of claim 1, comprising an end frame inserted in the front end of the outer tube, wherein said end frame is provided with concave indentations forming separate concave support sections, wherein the separate convex sections are arranged to fit into the concave support sections in the outer tube and the concave support sections in the end frame, thereby, the end section of the inner tube is pivotally received within the end section of the outer tube with the frame. ### Claim 4 (depends on 3) The reflex sight of claim 3, wherein the concave support sections in the end frame form at least portions of spherical caps. ### Claim 5 (depends on 2) The reflex sight of claim 2, wherein the spherical cap shaped support sections of the outer tube, and the corresponding convex spherical cap shaped sections of the inner tube, have essentially the same radius, and a common center point. ### Claim 6 (depends on 2) The reflex sight of claim 2, wherein at least a number of parts of the inner tube between the number of convex spherical cap shaped sections of the inner tube extend beyond a radius of the separate convex sections in the section of the inner tube perpendicular to the optical axis at the center point. ### Claim 7 (depends on 1) The reflex sight of claim 1, wherein the sight housing forms a longitudinal square-shaped outer tube and a longitudinal square-shaped inner tube. ### Claim 8 (depends on 1) The reflex sight of claim 1, wherein the sight housing forms a longitudinal outer tube and a longitudinal inner tube, having one of a triangular, rectangular, pentagonal, or hexagonal cross sectional shape. ### Claim 9 (depends on 2) The reflex sight of claim 2, wherein damping means is/are arranged between the end section of the inner tube and the end section of the outer tube. ### Claim 10 (depends on 9) The reflex sight of claim 9, wherein separate damping means are provided between the separate concave support sections of the outer tube and the separate convex sections of the inner tube. ### Claim 11 (depends on 9) The reflex sight of claim 9, wherein the damping means is an elastomer. ### Claim 12 (depends on 11) The reflex sight of claim 11, wherein the damping means is rubber. ### Claim 13 (depends on 9) The reflex sight of claim 9, wherein the damping means comprises at least one spring. ### Claim 14 (depends on 10) The reflex sight of claim 10, wherein each of the convex spherical cap shaped sections has a recess holding the damping means. ### Claim 15 (depends on 10) The reflex sight of claim 10, wherein each of the concave spherical cap shaped sections has a recess holding the damping means. ### Claim 16 (depends on 14) The reflex sight of claim 14, wherein each recess forms two circumferential spherical segments in the spherical cap shaped sections in the inner tube. ### Claim 17 (depends on 15) The reflex sight of claim 15, wherein the damping means is an o-ring. ### Claim 18 (depends on 1) The reflex sight of claim 1, wherein the end section of the outer tube is a separate section fixed to the outer tube, thereby forming the inner perimeter section of the outer tube. ### Claim 19 (depends on 10) The reflex sight of claim 10, wherein the separate damping means is an elastomer. ### Claim 20 (depends on 19) The reflex sight of claim 19, wherein the damping means is rubber.
