The DRS1X lives up to its namesake with rapid and lethal target engagement at close quarters.

The DRS (Defendu Reflex Sight) is so versatile and effective at close range, we’ve named it after the famed Lt. Colonel William Ewart Fairbairn whose Close Quarters Combat system was designed to rapidly disable an opponent with potentially lethal force. Perfect for tactical operations or home defense, the 1x reflex sight offers three reticles calibrated for speed and accuracy at 7, 25 and 50 yards.

The ultimate CQB sight, it is built with Steiner’s legendary ruggedness. Lightweight, compact and simple to use.
