The ACM 3-9x40EG is a full-size variable-magnification scope for sniper rifles and designated marksman builds. The 3x to 9x zoom and 40 mm objective give a bright, sharp picture at longer skirmish distances.
The range-estimating reticle can be lit red or green, with five brightness levels for each, which helps it stand out in poor light. The 1-inch (25.4 mm) one-piece aluminium alloy tube is nitrogen-purged, fog-resistant, water-sealed and shock-resistant. The lenses are fully multi-coated to cut glare, and the capped turrets adjust in 1/4 MOA clicks.
