Trijicon

**Trijicon** is an American optics company headquartered in Michigan that produces some of the most battle-tested optics in U.S. military service — most famously the **ACOG** (Advanced Combat Optical Gunsight) and more recently the **MRO** red dot and **RMR** miniature reflex sight. The ACOG is a 4x fixed-power prism optic with fiber-optic and tritium-illuminated reticles, widely used in the Iraq and Afghanistan wars and still a standard in U.S. Marine Corps and many foreign service rifles. The RMR is the reflex sight that defined pistol optics for most of the last decade before Holosun and Aimpoint closed the gap. Trijicon isn't cheap. The brand's reputation is built on durability and reticle clarity rather than price competitiveness, and buyers who want duty-grade optics without European prices land here often.
