The Angle Cosine Indicator (ACI) is an indispensable tool for long-range precision shooters and snipers when engaging targets at uphill or downhill angles. It allows you to effortlessly calculate and compensate for the effects of gravity on your bullet's trajectory.
Additionally, the integrated bubble level ensures your firearm is perfectly leveled, eliminating cant error.
Universal Integration: This ERATAC® mount attaches seamlessly to our UNIVERSAL-Interface without requiring any repositioning or adjustments to your riflescope.
Unobstructed Visibility: The ACI is strategically positioned so that the red indicator needle remains fully visible while you are aiming—even when utilizing scopes with left-side illumination controls.
Clear Turret View: Thanks to the side-mounted bubble level, your elevation turret always remains completely within your line of sight.
Mil-Spec Durability: Built to military standards, the Mil-Spec version is fully waterproof for up to 35 minutes at a depth of 1 meter.
