Tangent Theta Inc. Tangent Theta Long Range Hunter 3-15x50mm 36mm Tube Rifle Scope MRAD. The Long Range Hunter is a variable power telescopic rifle sight that can be rapidly adjusted for ballistic and environmental corrections by means of externally calibrated adjustment dials. The reticle is situated in the first focal plane allowing reticle subtentions to remain constant over all magnification ranges. The rifle telescope consists of a single piece main tube that encloses the optical components. All mechanical adjustments of the sight are controlled by the elevation and windage mechanisms at the top and right side of the tube. Illumination and parallax are controlled by the dial on the left side of the telescope tube. Magnification may be adjusted by the fluted ring forward of the eyepiece and diopter settings may be made at the rear of the eyepiece. The device incorporates a 50mm objective lens and 32mm eyepiece which provide excellent image quality in low light levels. It also provides for rapid target acquisition and identification at short intermediate and long ranges. The sight incorporates an LED for reticle illumination under low light conditions. The reticle consists of a cross hair with auxiliary stadia lines and dots to assist in shooting at various ranges. Specifications for Tangent Theta Inc.
