Various embodiments described herein may include a locking adjustment device having: a knob assembly being manually rotatable to adjust an optical device setting; a catch assembly defining a home position of the knob assembly whereat the catch assembly prevents rotation of the knob assembly in a clockwise or counterclockwise direction; and wherein the catch assembly includes a button or other lock-release arranged to, responsive to a manually-applied force, disengage a catch member from a catch opening or recess to allow the knob assembly to be rotated, in the clockwise or counterclockwise direction, from the home position to an adjustment position. Other embodiments may be disclosed and/or claimed.

Locking adjustment device

Rifle scopes with a locking feature including a body having an internal movable optical adjustor adapted to shift an image generated by the riflescope, a knob connected to the body for rotation about a knob axis and operably connected to the optical adjustor to position the optical adjustor based on a rotational position of the knob, an indicator skirt rotatably engaged to the body and threadedly engaged to the knob, the indicator skirt being operable to move axially with respect to the knob such that the axial position of the indicator skirt is based on the rotational position of the knob, and the knob including a knob stop surface and the indicator skirt including a skirt stop surface, wherein the knob stop surface and the skirt stop surface are configured to positively contact each other to establish a limit of rotational travel of the knob.

Firearm optic with locking feature

A rotatable adjustment device for a riflescope or other optical device includes a drive screw that is threadably coupled to a rotating spindle and constrained so that the drive screw translates along the axis of rotation of the spindle. The adjustment device further includes a stop screw that also translates along the axis in response to rotation of the spindle until the stop screw contacts an adjustment stop to limit further rotation of the spindle in the first rotational direction. Lost motion is reduced or avoided by a compliant gap between the drive screw and stop screw.

Reducing lost motion in adjustment knobs for riflescopes and other mechanically adjustable devices

Rifle scopes with zero locks or stops have a body having an internal movable optical adjustor adapted to shift an image generated by the riflescope, a knob connected to the body for rotation about a knob axis and operably connected to the optical adjustor to position the optical adjustor based on a rotational position of the knob, an indicator skirt rotatably engaged to the body and threadedly engaged to the knob, the indicator skirt being operable to move axially with respect to the knob such that the axial position of the indicator skirt is based on the rotational position of the knob, and the knob including a knob stop surface and the indicator skirt including a skirt stop surface, wherein the knob stop surface and the skirt stop surface are configured to positively contact each other to establish a limit of rotational travel of the knob.
