Red Dot Sights — Fast Acquisition Optics for Rifles & Handguns

Shop red dot sights at Tactical Surplus USA from the brands that set the standard in modern optics — Trijicon, Holosun, EOTech, Sig Sauer, Vortex, and more. A quality red dot sight is one of the highest-impact upgrades you can make to any rifle or handgun, offering faster target acquisition, improved accuracy at speed, and better performance in low-light conditions compared to traditional iron sights.

Our red dot inventory spans the full range from budget-friendly options under $150 to professional-grade duty optics trusted by military and law enforcement. Whether you're mounting a compact dot on a carry pistol, running a full-size reflex sight on your AR-15, or adding a co-witness setup for backup irons, we have the right optic for your platform and your budget.

Not sure which red dot to choose? Our optics buying guides cover the most important specs — MOA dot size, battery life, mounting footprint compatibility, and durability ratings — so you can buy the right optic the first time.
