Patent ID: 7934335

Claim:
An apparatus for engaging an adjustment mechanism for a sighting device, comprising a cap having (1) an outer annular surface that is grippable by a user and (2) a rotational axis, wherein the cap is operative for axially translating along the axis between (a) a first closed axial position where rotation of the cap does not engage the adjustment mechanism and (b) a second extended axial position where rotation of the cap actuates the adjustment mechanism for making a position adjustment to an internal component of the sighting device, wherein in the first axial position, the cap is rotatable from (i) a first rotational position at which the cap is restrained from axial translation to (ii) a second rotational position at which the cap is released for axial translation from the first closed axial position to the second extended axial position, wherein the cap is constructed and arranged to remain connected to the sighting device in both the first closed position and the second extended position.
