Patent attributes
A firearm sight, optionally having a 45° offset mount, including a sight element selectively configurable in upright position and down positions, and a moveable plunger configurable in a locking mode in which a head of the plunger protrudes from it such that upon rotation of the sight element about a pivot axis, the head engages a plunger wall of the mount to arrest such rotation to thereby maintain the sight element substantially in the upright position, the plunger alternatively configurable in a free mode in which the head is retracted into the sight element so the head clears the plunger wall and the sight element can move to the down position. The mount can include an extension stop wall adjacent the head so the head cannot be deployed from the sight element to maintain it in the down position. The plunger can be actuated ambidextrously. A related method is provided.
