Bushnell RXM-300 1x 28mm 4 MOA Red Dot Reflex Sight

The Bushnell RXM-300 is a large-format open reflex sight built around a parallax-free optical system (optimized at 50 yards), with a wide 28mm objective window and a crisp 4 MOA red dot reticle. The 1x viewing image pairs with a 4 MOA dot that picks up quickly on the slide of a pistol without burying the target.

The optic runs on a single CR2032 lithium battery rated for over 35,000 hours of runtime and includes a shake-awake function that brings the dot back to life on motion. Twelve brightness settings cover daylight to low-light use, with an auto-ambient mode that adjusts the dot intensity to the surrounding environment. Adjustable windage and elevation let you dial in a precise zero for your platform.

The matte black housing is sealed and protected by Bushnell's EXO Barrier coating for fog-proof and waterproof performance in adverse conditions. At 1.95 oz, the RXM-300 keeps carry-friendly pistols light, and the included low and high mounting bases let you configure the sight to a wide range of slide cuts and optics-ready platforms.
