The Trijicon ACOG 3×30 with 300 AAC Blackout reticle features a battery-free, self-illuminated reticle with a ballistic drop compensator for both supersonic and subsonic rounds. One of its key features is the Bindon Aiming Concept, which allows for both-eyes-open shooting. The reticle utilizes standard 16 inch barrel velocities and is designed to be calibrated with supersonic (115 gr.) ammo using a zero of 100 yards.
