Micrometric rifle sight

An improved micrometric rifle sight, which is placed on the dovetails located on the gun's barrel, which guarantees an acceptable shot grouping operation, and which is formed by a base, consisting of two pieces:

• a fixed part and a moving part, the latter forming the clamp, and both parts attached to the slide on the dovetail, located towards the back of the gun's barrel;
• an upper support joined to a side plate to form an angled piece;
• several set-screws with a ball bearing at the end to press the back face of the angled plate, a micrometric height adjustment screw on the upper support of the sight, either an open or closed sight, mounted on the top surface of the upper support, a micrometric moving and adjustment screw of the open or closed sight, characterized because the fixed base is formed by a rectangular piece, with a small protuberance that sticks out downward and which has a slide or dovetail on its left face on which the angled plate of the upper support moves, and at the end of which appear several cavities located on the front face of the fixed base coinciding with the rear face of the angled plate, where the spring and ball are inserted at the end, and this is angled plate also has a small inclined cut-out on its side faces for its movement, correlative to the dovetail on the gun's barrel, on which it rests and to which it is secured, located towards the opposite part of the left face. Additionally, the top face of this fixed base has a hole with a fine thread, through which the micrometric screw passes, and on the top face of the fixed base there is a flat rectangular plate, which acts as a screen and avoids the distraction of the user;
• the movable part or clamp of the base is provided with a small rectangular piece that has a small inclined cut-out on the inside face, correlative to the dovetail on the gun's barrel, on which it rests and to which it is secured, which is located towards the opposite part of the left face;
• several set-screws which are placed transversely to the clamp that are used to secure the fixed base to the clamp and to the dovetail on the gun's barrel and which exerts sufficient pressure to be able to absorb any imperfection that may exists in the dovetail on the gun's barrel;
• the upper support, formed by a rectangular piece, with a flat plate at one end, forming an angled piece, and with a small cut-out on its side faces correlative to the geometry of the dovetail slides on the fixed base, as well as being provided with a scale indicated with divisions as a reference in relation to the height at which the upper support should be placed, this flat plate being fastened in a determined position by means of the springs at one end with a ball bearing that exerts pressure on the rear face of the angled plate, whose function is to exert pressure on the angled plate and keep it in position;
• the micrometric height adjustment screw placed on the top face of the upper support, consisting of a screw with a fine thread and provided with a fluted crown on which the ball bearing rests and by means of which the height of the upper support may be precisely- and finely adjusted;
• this ball being located perpendicular to the movement of the shank of the micrometric screw;
• additionally, the body of the upper support has a rectangular hole and a scale marked with divisions as a reference in relation to the centering of the sight;
• the open sight is formed by an angled plate, with a small cut-out situated centrally for sighting, and a rectangular protuberance, which is situated towards the bottom of the horizontal angled plate and coincides with the rectangular hole that acts as a guide through which the upper support moves and is fastened to the upper support by means of a micrometric centering screw, consisting of a screw with a fine thread and a fluted crown where a ball bearing rests, which allows the precise and fine centering movement of the sight, this ball bearing being held in place perpendicular to the movement of the micrometric centering screw;
• and the closed sight, formed by a cylindrical piece with a central eyepiece (notch) for sighting, and a rectangular protuberance, which is located towards the bottom of the horizontal angled piece and coincides with the rectangular hole that acts as a guide through which the upper support moves and to which it is attached by means of a micrometric centering screw.
