Riflescope turret dial connection and method

A connection assembly for a viewing optic turret having a leadscrew and a dial, the connection assembly comprising:

• a collet having a plurality of flexures, wherein the collet is connected to the dial such that the collet rotates with the dial;
• a fastener extending along an axis;
• and
• a plug having a threaded bore that is threadably engaged with the fastener such that rotation of the fastener causes the plug to translate along the axis,
• wherein, when the fastener is rotated in a first rotational direction, the plug acts upon the collet to radially expand or contract the collet and thereby engage the leadscrew, and the collet disengages the leadscrew upon rotation of the fastener in a second rotational direction opposite the first rotational direction.

A riflescope having an adjustable reticle, comprising:

• tubular body extending along a longitudinal axis between a proximal end and a distal end;
• a turret housing protruding radially outward from the tubular body, the turret housing defining an inner cavity;
• a leadscrew at least partially arranged in the inner cavity and extending into the tubular body, wherein the leadscrew is operable to adjust position of the reticle upon rotation of the leadscrew;
• a dial arranged on the turret housing to enclose the inner cavity;
• and
• a connection assembly comprising:
• a collet connected to the dial such that the collet rotates with the dial, the collet having a plurality of flexures;
• a fastener extending along an axis and having threads;
• and
• a plug having a threaded bore that is threadably engaged with the fastener such that rotation of the fastener causes the plug to translate along the axis,
• wherein, when the fastener is rotated in a first rotational direction, the plug acts upon the collet to radially deflect the collet into engagement with the leadscrew such that the dial and the leadscrew are rotationally coupled, and the collet disengages the leadscrew upon rotation of the fastener in a second rotational direction opposite the first rotational direction such that the dial and the leadscrew are rotationally uncoupled.
