Special Features
- The Flat Dark Earth finish coordinates with FDE handguards, stocks, and frame accessories, giving tan and earth-tone pistol and rifle builds a matched, cohesive appearance without painting or wrapping.
- Motion Sensor Technology automatically deactivates the dot after five minutes of inactivity and reactivates it instantly on any movement, preserving battery life without sacrificing draw-ready response.
- The DiamondCoat aspheric lens delivers scratch resistance and optical clarity across the full window, eliminating edge distortion and brightness loss that standard spherical lenses introduce.
- The tool-less spring-actuated battery compartment allows a CR2032 swap without removing the sight from the slide and without disturbing your established zero.
Practical Benefits
- The DeltaPoint Pro footprint mounts directly to Sig P320, Glock MOS, S&W M&P, and other factory optics-ready slides across a wide range of duty and competition pistols without an adapter plate.
- The spring steel shroud protects the aluminum housing and lens from direct impact and slide cycling wear, a durability advantage over unprotected open emitter designs in the same size class.
- Your 175840 gives you a motion-activated, American-made reflex sight in a tan finish that matches your build, holds zero through hard carry, and carries Leupold's lifetime guarantee behind every round.
The Leupold DeltaPoint Pro Reflex Sight (175840) with its 2.5 MOA red dot in Flat Dark Earth is a solid fit for duty shooters, hunters, and FDE platform builders who want a precision American-made open reflex sight with motion-sensing power management on the most compatible optic footprint in the industry.
