ADJUSTABLE REAR SIGHT FOR A FIREARM

摘要

A rear gun sight mountable to a firearm that includes an aperture module defining a gun sight aperture and a base. The base defines a recess for receiving the aperture module and the aperture module includes ribs that are slidably received by associated recess in the base to constrict the aperture module to relative rectilinear movement with respect to the base. At least one spring acts between the base and the aperture module. An adjustment member couples the module to the base such that rotation of the adjustment member moves the module towards and away from the base depending on direction of rotation. A detent resists uncontrolled rotation of the adjustment member. The aperture module includes a recess for receiving a light emitting member such as a tritium module.

主权项

1. A rear gun sight for a fire arm comprising:
a) a base including structure for removably mounting said base to a fire arm; b) an aperture module defining a gun sight aperture; c) said base defining a recess for receiving said aperture module, said aperture module and base defining locating surfaces that confront each other when said aperture module is received by said recess; d) at least one rib formed on one of said base and aperture module and an associated recess for slidably receiving said rib formed on the other of said base and aperture module for constricting movement of said module to rectilinear movement with respect to said base; e) at least one spring acting between said base and said aperture module for urging said aperture module away from said base; f) an adjustment member for adjustably coupling said module to said base, such that rotation of said adjustment member moves said aperture module towards and away from said base depending on the direction of rotation; and g) a detent for resisting uncontrolled rotation of said adjustment member.
