Spuhr ACI & A-0023 INTERFACE

The Sniper Tools Angle Cosine Indicator (ACI,) is a simple tool for snipers/hunters in mountainous terrain for determining the angle to the target so that adjustments can be made to achieve the correct Point-of-Impact. The “Mil Spec” ACI is a vault solid, water proof precision instrument (as per US Military Specs;) quiet, and made from aircraft grade aluminum, which is anodized in a flat black color. The cosine numbers are laser engraved onto the body in 5-degree increments. The lens is shatter proof, shock proof, and resistant to chemicals such as acetone and cleaning solvents. Completely mechanical, there are no batteries to fail or electronics to fail.
