Abstract: A reflex sight to sight a weapon, such as a firearm, comprises a frame carried by a base. The frame carries a mirror and an illumination source, such as an LED, spaced-apart and in a fixed relationship with respect to one another with the illumination source directed towards the mirror at a fixed orientation. A spindle is carried by the frame and disposed between the frame and the base about which an orientation of the frame with respect to the base is adjusted. The spindle has a vertical shaft extending between the base and the frame, with the frame capable of swiveling horizontally on the vertical shaft to adjust for azimuth. The spindle also has a horizontal axle extending between the vertical shaft and the frame, with the frame vertically pivotal on the horizontal axle to adjust for elevation.

Abstract: In some embodiments, a method includes: selecting dimensions of a slot to be provided in a device feature, the dimensions selected to accommodate one or more tools while resulting in tangential contact between the slot and the one or more tools when the one or more tools are inserted into the slot and used to manipulate the device feature; and forming the slot in a surface of the device feature according to the selected dimensions.

Abstract: A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

Abstract: A close quarters battlefield (CQB) sight is provided. The CQB sight includes an optical sighting element and a base plate to which the optical sighting element is integrally coupled. The base plate includes a flange and a mounting surface formed to complement a mounting surface of another optical sighting element. The flange is configured to be fastened to the another optical sighting element such that the mounting surfaces abut and the optical sighting elements become co-aligned.
