A rifle scope including a display, at least one optical sensor to capture video of a view area, and image processing circuitry coupled to the display and the at least one optical sensor. The presence of a HFWM at a zero crossing of the wobble indicates an active bit and the absence of the HFWM indicates an inactive bit. The body comprises a ring core of a first, hard polymeric material, and a covering of a second, soft polymeric thermosetting material, natural rubber, or mixture of a thermosetting and non-thermosetting material which may be frictionally connected, thermally and chemically bonded, or otherwise mechanically interconnected to the first polymeric material.
