The NCStar D4BQ red reflex sight brings versatile aiming options to shotguns, rifles, and pistols without magnification or batteries holding you back. This compact red dot sight features four switchable reticles—dot, bullseye, cross, and starburst—so you can dial in the aiming pattern that works best for your shooting style and distance. The reflex design delivers unlimited eye relief, meaning you can mount it almost anywhere on a Weaver or Picatinny rail and still get a clean sight picture from any shooting position.
Built from black anodized aluminum, the D4BQ handles the wear and tear of the field. At just 3.2 inches long and designed for quick target acquisition, it's equally at home on a home-defense shotgun, a competition rifle, or a hunting setup where speed matters. The 24x34mm objective lens gathers enough light for use in low conditions, and the 3 MOA dot size strikes a balance between precision and speed—fine enough for accurate aiming yet bold enough to find fast. The sight runs on a single CR2032 battery with a spare included, and because it's an LED optic, it's safe for your eyes even in close-quarters shooting.
Setup is straightforward: the quick-release Picatinny mount clamps securely to any standard rail, and NCStar includes adjustment tools to zero the reticle to your firearm. The included rubber lens cap protects the optics when not in use. Whether you're training at the range, setting up a defensive gun, or hunting in open country, the D4BQ's multi-reticle flexibility and no-frills reliability make it a practical choice.
