US12710250 - Dovetail reflex sight and interface for mounting to a firearm

To allow a reflex sight to be mounted to the slider of a handgun and removed without the need for tools, an adapter shoe may be secured to the slider to provide an interface between an optics-ready recess of the slider and a mounting element that forms part of the reflex sight assembly. The adapter shoe may provide a dovetail track that engages complementary dovetail features of the mounting element. A push button retention mechanism may be biased to lock the mounting element within the adapter shoe. Actuation of the push buttons may retract the retention mechanism and allow the reflex sight assembly to slide out of the dovetail track.

Claim 1

1 . A reflex sighting system removably mountable to a slider of a handgun, the reflex sight comprising: (A) a lens; (B) a light source; (C) a battery for powering the light source; (D) electronics for controlling the operation of the light source; and (E) a housing that houses one or more of the battery and the electronics; (F) a mounting element that is configured to mount the reflex sight to the slider, the mounting element comprising: (a) a sight mounting component comprising: (i) a sight mounting surface on which the reflex sight may be mounted and secured; and (ii) a first complementary lateral dovetail engagement feature; (b) an adapter shoe comprising: (i) a first mounting portion for mounting the adapter shoe to the slider; and (ii) a second mounting portion comprising a second complementary lateral dovetail engagement feature that is complementary to the first complementary lateral dovetail engagement feature; wherein the first complementary lateral dovetail engagement feature and the second complementary lateral dovetail engagement feature each comprise a dovetail profile and wherein the sight mounting portion is configured to slide laterally along a dovetail track provided by the adapter shoe. (A) a lens; (B) a light source; (C) a battery for powering the light source; (D) electronics for controlling the operation of the light source; and (E) a housing that houses one or more of the battery and the electronics; (F) a mounting element that is configured to mount the reflex sight to the slider, the mounting element comprising: (a) a sight mounting component comprising: (i) a sight mounting surface on which the reflex sight may be mounted and secured; and (ii) a first complementary lateral dovetail engagement feature; (b) an adapter shoe comprising: (i) a first mounting portion for mounting the adapter shoe to the slider; and (ii) a second mounting portion comprising a second complementary lateral dovetail engagement feature that is complementary to the first complementary lateral dovetail engagement feature; wherein the first complementary lateral dovetail engagement feature and the second complementary lateral dovetail engagement feature each comprise a dovetail profile and wherein the sight mounting portion is configured to slide laterally along a dovetail track provided by the adapter shoe. (a) a sight mounting component comprising: (i) a sight mounting surface on which the reflex sight may be mounted and secured; and (ii) a first complementary lateral dovetail engagement feature; (i) a sight mounting surface on which the reflex sight may be mounted and secured; and (ii) a first complementary lateral dovetail engagement feature; (b) an adapter shoe comprising: (i) a first mounting portion for mounting the adapter shoe to the slider; and (ii) a second mounting portion comprising a second complementary lateral dovetail engagement feature that is complementary to the first complementary lateral dovetail engagement feature; (i) a first mounting portion for mounting the adapter shoe to the slider; and (ii) a second mounting portion comprising a second complementary lateral dovetail engagement feature that is complementary to the first complementary lateral dovetail engagement feature; wherein the first complementary lateral dovetail engagement feature and the second complementary lateral dovetail engagement feature each comprise a dovetail profile and wherein the sight mounting portion is configured to slide laterally along a dovetail track provided by the adapter shoe.
