  • Patent number: 10337832
    Abstract: An illumination system for weapon optics includes a light source and one or more channels that direct light from the light source onto adjustment interfaces of a weapon optical device, such as windage and elevation turrets of a scope. An illumination system for weapon optics may also include an illuminated level device for positioning the weapon level in relation to the surface of the earth. An illumination system for weapon optics illuminates the level device and/or adjustment interfaces of a weapon optical device such that the level device and/or markings on the adjustment interfaces can be read in low-light and no-light conditions.

  • Patent number: 10048040
    Abstract: The present disclosure provides an adjustable attachment system and method that can adjust for a variety of gaps between an accessory mounting system and a weapon mounting system, caused by tolerances in manufacturing. In at least one embodiment, a combination of keys can be provided with a first key having a thickness that is in a middle range of a predetermined tolerance, a second key having a greater thickness by a given percentage, and a third key having a lesser thickness by a given percentage. One or more of the keys can be coupled between surfaces of the accessory mounting system and the weapon mounting system, depending on the gap size. In another embodiment, at least one key can have a tapered lateral surface. The variable sized key can compensate for the variety of gaps by the lateral position of the key in the gap.
