NCSTAR D4B Red Four-Reticle Reflex Sight

The NCSTAR D4B is a compact 1x open reflex sight with four selectable red reticle patterns. You can switch among a dot, starburst, cross, and bullseye without changing the optic or mount. The black sight clamps directly to a Weaver or Picatinny rail.

Seven brightness settings let the red reticle be adjusted for different ambient light levels. Unlimited eye relief gives the sight flexibility in mounting position, while the open window keeps the view less enclosed than a tube-style dot. The lightweight housing is intended for a simple, low-magnification aiming setup.

This version is the red-only alternative to the D4RGB model that adds a second reticle color. It works well when multiple reticle shapes are useful but color switching is not needed. Browse more optics and rangefinders for enclosed red dots, magnifiers, and variable-power scopes.
