Abstract: An accessory system for a firearm includes a target sight secured to a mounting rail of the firearm, an accessory secured to the mounting rail of the firearm, a sensor configured to sense a position of the accessory, and a processor configured to receive input from the sensor and adjust an operating mode of the target sight based on the input from the sensor. The sensor may be a magnetic sensor, a proximity sensor, an ambient light sensor, or a switch. Methods are also described.

Abstract: An accessory mounting system for securing an accessory to a firearm includes a slot in a first end of a receiving portion of the firearm, a tab protruding from one end of the accessory, the tab structured to mechanically engage with the slot, and a fastener structured to clamp a portion of the accessory to the receiving portion of the firearm in a location apart from the slot.

Abstract: An optical sighting device includes an electronic controller that is responsive to changes in an optical magnification of the sighting device to resize at least a portion of a reticle produced by an electronic display or other means proximate a focal plane of the sighting device. In some embodiments, the reticle is located proximate a rear focal plane of the sighting device and may be scaled by the electronic controller in concert with changes in optical magnification to simulate a front focal plane reticle. A functional pattern of the reticle may also be automatically changed at different magnification settings to provide different types of reticles, such as CQB and sniper reticles, in a single optical device.
