Trijicon is a U.S.-based manufacturer of professional-grade aiming optics, long recognized for durable, mission-ready solutions engineered for reliable performance across diverse lighting conditions. Since its founding in 1981, the company has played a pivotal role in the evolution of modern combat and tactical optics, driven by a commitment to practical design, rugged construction, and consistent real-world performance. Trijicon products are developed for operational use and are trusted by civilian shooters, military personnel, and law enforcement professionals alike.

Among the brand’s most prominent products are optics fielded by U.S. armed forces. Trijicon supplies the official Rifle Combat Optic (RCO) and Squad Common Optic (SCO) to the U.S. Marine Corps (ACOG and VCOG series), and its RMR miniature red dot sights were selected as the USSOCOM Miniature Aiming System – Day Optic. The company also maintains long-standing partnerships with federal, state, and local law enforcement agencies, particularly in the field of tritium-powered night sights.

The brand’s portfolio includes product lines whose abbreviations have become established terms within tactical optics:

• ACOG (Advanced Combat Optical Gunsight) – compact fixed-magnification riflescopes featuring tritium and fiber-optic illuminated reticles. Known for mechanical durability, simplicity, and rapid target engagement, including the ability to shoot effectively with both eyes open.
• VCOG (Variable Combat Optical Gunsight) – variable-power riflescopes designed for duty and tactical applications, combining the rugged construction associated with ACOG models and the flexibility of variable magnification.
• RMR (Ruggedized Miniature Reflex) – highly durable miniature red dot sights originally developed for military use and now widely deployed on pistols and long guns.
• MRO (Miniature Rifle Optic) – compact red dot sights for rifles and carbines, designed with an emphasis on wide field of view and rapid target acquisition.

In addition to these core series, Trijicon’s portfolio includes variable-power riflescopes for tactical, competitive, and hunting applications, tritium night sights, electro-optical systems including thermal imaging devices, and precision mounting solutions engineered to maintain zero under sustained and demanding use.

A defining characteristic of Trijicon is its emphasis on durability, extended service life, and consistent performance. Many products are designed to meet or exceed military testing standards. Most primary product lines are designed, machined, and assembled in the United States, with standardized quality control and testing procedures applied across all manufacturing locations.

Intended use and application: Trijicon products are suited for users who prioritize long-term reliability, mechanical resilience, and predictable optic performance in challenging environments. They are utilized by military and law enforcement personnel, dedicated range shooters, competitive marksmen, and hunters.

Trijicon is not positioned as a budget or short-term solution. It is intended for users seeking optics engineered for sustained performance without compromise in durability, functionality, or reliability.
