MECHANICAL SIGHT OF FIRE ARMS

摘要

FIELD: weapons and ammunition.SUBSTANCE: invention relates to fire arms, particularly to open mechanical sights. Proposed sight comprises foresight (1) fitted on base (2) at barrel front (3), block (4) secured at the rear of gun breech frame (5). Top part of block (4) has guide surface a. Backsight (7) with aiming cut-out b is articulated at axle (6) of block (4). Clip (8) slides on backsight (7). Backsight (7) is clamped by spring (9) by clip (8) to block (4) guide surface a. Fork lever (11) articulated with axle (10) inside block (4), another guide surface c is made at top part of said lever its profile differing from that of guide surface a at block (4). Eccentric coupling (13) to be turned by lever (14) of pin (12) is arranged under lever (11) on said pin (12). Lever (14) is made of spring steel. Ledge is made on the side of block (4) at lever (14) to fit in mating cut-outs d on side surface of block (4).EFFECT: higher precision of setting the gun elevation angles at fire with different ballistic shells.3 dwg
