Big Hawk II (BII) Side Focus Scopes Overview
Big Hawk II (BII) side focus scopes have a good reputation in Optical System and rugged construction.
The distinguished optical feature of BII scopes is Durable Adjustable Side Focus, which allows parallax focusing adjustment from 10 YDS to infinity only by fine tune of side focus knob. The small and fine operation action of “Side Focus” operation action is in favor of shooter’s hide. Tactical advantage is more obvious. The use of Fully coated lenses with Multi-layer Broad Band Anti-reflective Coatings are beneficial to increase light transmittance to get maximum clarity. Fast focus eyebell is beneficial for users to focus their personal eye characteristics easily. Reliable fingertip (1/4” or 1/8”) W/E turrets provide users with smooth and precise Windage / Elevation adjustments.
BII scopes have rugged mechanical designs and superior erector system. The single-tube scope body is made from Aircraft grade Nitrogen Purged aluminum alloy sealed with O-ring which assure waterproof, fog proof and shockproof. This also extremely enlarges the range of using conditions. Anti-scratch matte black surface treatments preventing surface scratch and reflection are in favor of scopes’ maintenance and shooter’s better hide.
Meanwhile, Dual Illuminated Glass Reticle (IGR) in Red & Green is also available for BII scopes. It makes users easily catch visible target in low light and poor contrast environment.
