ACSS HUD DMR .308 reticle

The ACSS HUD DMR reticle is designed for designated marksman applications and optimized for .308 Winchester ammunition, as well as cartridges with similar ballistic profiles. At its center is a precise inverted V-shaped chevron that serves as the main aiming point, surrounded by a horseshoe that allows rapid target acquisition at short and medium ranges.

This reticle goes beyond traditional crosshairs by incorporating an advanced bullet drop compensation system calibrated out to 1,000 yards. It also features a built-in ranging ladder, moving-target leads, and wind hold references, allowing confident and efficient shooting without the need for constant turret adjustments or external ballistic calculations.
