L3Harris Technologies EXPS2 Optical sight/accessory

The EOTech EXPS2 holographic weapon sight is purpose-built for tactical professionals who demand fast, accurate target acquisition in high-stress environments. Designed for law enforcement, military, and civilian operators, this reflex optic eliminates the need to align front and rear sights by enabling true 2-eyes-open shooting—critical when situational awareness and peripheral vision can determine operational success. The EXPS2 delivers an unmatched targeting experience across close-quarters combat, dynamic room clearing, and intermediate-range engagements where split-second precision matters.

The EXPS2 features a side-button brightness adjustment system for rapid reticle tuning in varying light conditions, paired with a quick-detach lever that enables seamless mounting and removal without tools or zero loss. The transversely-mounted lithium 123 battery is accessible from the side, allowing field replacement without removing the optic from the rail—a critical design advantage in sustained operations. Built with an elevated optical axis, the EXPS2 maintains full co-witness compatibility with standard iron sights, allowing backup sighting systems to remain operational. The compact 6.65 x 3.7 x 7.6-inch form factor and 1.24-pound weight minimize center-of-gravity shift and optical obstruction while maintaining durability in harsh tactical environments.

The EXPS2 performs optimally on AR-pattern rifles, carbines, and sub-guns across 5.56mm NATO, 9mm, and .308 platforms where co-witness integration is essential. Operators conducting building assaults, mounted operations, or dynamic CQB scenarios benefit most from the 2-eyes-open ergonomics and rapid target transitions. Installation requires standard Picatinny rail space; the quick-detach lever accommodates rapid optic swaps between platforms without affecting zero or reticle alignment—a proven advantage in multi-gun tactical environments and training rotations.
