Ring front sight for sports rifle - involves two customary ring sights in tunnel determining internal and external diameters of sight and iris aperture for viewing through inner and outer diameters

摘要

Two ring sights (3, 4) are arranged one behind the other in the sight tunnel (1) and their push sockets are connected via their discs (9, 10) with push cylinders (12, 13) located by the sight tunnel inner walling. The push cylinders are displaceable longitudinally via rotatably arranged adjustment rings (14, 15). The push cylinders (12, 13) engage in one another coaxially and lead to the threaded adjustment rings (14, 15) on the free face side of the sight tunnel. The push cylinders are connected to a push muff which is provided with a spirally running groove in which adjustment pins of the adjustment rings engage. Alternatively, the push cylinder (12) located near to the sight tunnel screw thread is connected to a push muff whilst the other such cylinder (13) leads to a face-side threaded adjustment ring (14). USE/ADVANTAGE - A ring front sight for a sports rifle in which two sights arranged in a tunnel permit the adjustment of both the sight inner and outer diameters.
