Enclosed Red Dot Sights – Rugged Reflex Optics for Pistols, Rifles & Shotguns
🎯 Built for Duty. Designed to Last.
When durability and reliability matter most, an enclosed red dot sight is the gold standard. Unlike open emitter optics, enclosed red dots protect the LED emitter within a sealed housing — keeping out water, dirt, debris, and fog. Whether you're mounting it on a Glock MOS, AR-15, SIG P320, or tactical shotgun, these optics are built for rugged environments and real-world performance.
At Mounts Plus, we carry a carefully selected collection of top-tier enclosed red dot sights from brands like Trijicon, Holosun, Steiner, SIG Sauer, and more — trusted by law enforcement, competitive shooters, and tactical pros.
