Steiner Drs1x W/ Std Mount

The Steiner DRS1x with standard mount is a compact reflex sight purpose-built for close-quarters combat and rapid target acquisition in high-stress tactical environments. Named after Lt. Colonel William Ewart Fairbairn's legendary CQC system, this optic delivers the speed and reliability demanded by law enforcement, military operators, and serious defensive shooters who require instant target pickup at intermediate ranges. Whether mounted on a rifle, carbine, or designated marksman platform, the DRS1x bridges the gap between traditional iron sights and advanced glass optics with rugged simplicity.

The DRS1x employs a non-magnified, 1x optical design that preserves your natural field of view and allows both-eyes-open shooting without accommodation lag—critical for CQB scenarios where split-second decisions define outcomes. The open reflex sight window minimizes parallax error at typical engagement distances, while Steiner's optical coating ensures light transmission even in dim tactical environments. At just 0.88 lbs, the sight adds negligible weight to your system, and the 5.0 x 2.5 x 7.0 inch form factor maintains a low profile without sacrificing sight picture clarity or durability. The standard Picatinny mount integrates seamlessly with modern tactical platforms.

This sight is ideal for operators running patrol rifles, defensive carbines, or home-defense platforms where engagement distances rarely exceed 50 yards but speed matters absolutely. The compact footprint allows co-witnessing with backup iron sights, and the standard mount accommodates virtually all Picatinny-equipped uppers and receivers. Law enforcement tactical teams, private security, and civilian preparedness shooters benefit from the DRS1x's balance of speed and accuracy without the battery dependency of electronic optics. Installation is straightforward: secure the mount to your upper receiver rail using standard hardware, level the optic, and verify zero at your preferred distance.
