Quick Answer: Best Trijicon Optics in 2026

Best Overall Red Dot: Trijicon RMR Type 2 ($549-$650) - The gold standard. Patented housing survives abuse that destroys competitors. Duty, carry, and offset rifle use.

Best Rifle Red Dot: Trijicon MRO ($479-$520) - Enclosed emitter with 25mm objective and 5-year battery. Trijicon's answer to the Aimpoint T2.

Best Competition Sight: Trijicon SRO ($549-$599) - Widest window in the Trijicon lineup. Built for speed, not maximum durability.

Best Combat Optic: Trijicon ACOG TA31 ($1,199-$1,843) - Battery-free. Battle-proven since 1987. The optic Marines trust.

Best LPVO: Trijicon Credo HX 1-8x28 ($1,899-$2,099) - Premium Japanese glass with 28mm objective for exceptional low-light performance.

Why Trijicon: Military Heritage Meets Civilian Excellence

Trijicon, headquartered in Wixom, Michigan, has supplied the U.S. military with combat optics since the late 1980s. The ACOG became the official Rifle Combat Optic (RCO) of the U.S. Marine Corps in 2004. The RMR Type 2 was selected for USSOCOM. This is not marketing — it is procurement history. When you buy Trijicon, you buy the same engineering that goes downrange with special operations forces.

Trijicon Advantages

  • +U.S. military combat-proven across all product lines
  • +Forged 7075-T6 aluminum (RMR, ACOG, MRO)
  • +Battery-free illumination on ACOG (tritium + fiber)
  • +Made in USA (RMR, SRO, MRO, ACOG)
  • +Lifetime warranty on housing and materials

Considerations

  • -Premium pricing across the entire lineup
  • -Fewer tech features than Holosun (no solar, no shake awake)
  • -ACOG tritium dims over 12-year half-life
  • -Conservative design philosophy (reliability over innovation)
  • -RMR bottom-loading battery requires removal

Best Trijicon Red Dots & Reflex Sights

Three distinct optics for three different missions. The RMR is the duty standard, the MRO dominates enclosed rifle red dots, and the SRO wins on speed for competition shooters.

Best Trijicon Red Dots & Reflex Sights

Trijicon's red dot lineup spans micro reflex sights to full-size enclosed optics. The RMR defined the category, the SRO optimized for speed, and the MRO brought enclosed reliability to rifles.

Frequently Asked Questions

▶Is Trijicon made in the USA?
Trijicon headquarters and primary manufacturing are in Wixom, Michigan, USA. The RMR, SRO, MRO, and ACOG are all made in the USA. Their AccuPoint riflescopes are assembled in the USA with significant Japanese components. The Credo, Huron, Ascent, and Tenmile riflescopes are manufactured in Japan to Trijicon specifications and quality standards.
▶Which is better, Aimpoint or Trijicon?
It depends on the optic category. For enclosed rifle red dots, Aimpoint (T2, CompM5) has a longer combat track record than the Trijicon MRO, but the MRO offers a larger sight picture at a lower price. For miniature reflex sights, the Trijicon RMR Type 2 is the gold standard with no true Aimpoint equivalent. For fixed combat optics, the ACOG has no Aimpoint competitor. Both brands are duty-grade and military-proven.
▶What is the best Trijicon optic for AR-15?
The Trijicon MRO ($479-520) is the best Trijicon for most AR-15 shooters. Its enclosed housing, 25mm objective, and 5-year battery life make it a true set-and-forget rifle optic. For magnified use, the ACOG TA31 ($1,199+) is unmatched in durability with battery-free illumination. For those wanting variable magnification, the Credo HX 1-8x28 ($1,899) offers premium glass quality.
▶What is the difference between the Trijicon RMR and SRO?
The RMR is built for maximum durability with a patented housing that absorbs impacts, waterproof to 20 meters, and designed for duty/carry use. The SRO has a wider window for faster target acquisition, is purpose-built for competition, but is less impact-resistant and only waterproof to 1 meter. Both share the same RMR footprint for mounts. Choose RMR for duty, SRO for competition.
▶Do military units use Trijicon optics?
Yes. The Trijicon ACOG has been the official Rifle Combat Optic (RCO) of the U.S. Marine Corps since 2004 and is widely used across all U.S. military branches. The RMR Type 2 was selected for the USSOCOM Miniature Aiming System Day Optics Program. Trijicon optics are standard issue for many NATO forces. The ACOG alone has more combat deployments than any other magnified optic in history.
▶Are Trijicon scopes any good?
Trijicon scopes are considered premium-tier across all categories. The ACOG is the most combat-proven magnified optic in history. The RMR defined the pistol red dot category. Their Credo and AccuPoint riflescopes use high-quality Japanese glass. The main consideration is price. Trijicon optics cost significantly more than budget alternatives like Holosun, but you get military-grade durability, superior glass, and a brand trusted by professionals worldwide.
▶How long does Trijicon tritium last?
Tritium has a half-life of approximately 12.3 years, meaning ACOG and other tritium-illuminated optics will be at 50% brightness after about 12 years. The optic itself is fine, but the tritium glow dims over time. Trijicon offers tritium replacement service (not covered under warranty). Most users report usable nighttime illumination for 10-15 years. Fiber optic daytime illumination is unaffected since it runs on ambient light.
▶Is the Trijicon MRO better than Holosun AEMS?
The MRO ($479) and AEMS ($380) serve similar roles but differ in philosophy. The MRO offers a larger 25mm objective, 5-year battery, and Trijicon's military pedigree. The AEMS offers Multi-Reticle System (dot, circle, or both), Solar Failsafe backup, and Shake Awake auto-on. For duty use where brand reputation and proven durability matter, MRO wins. For features per dollar, the AEMS wins. Both are enclosed and duty-capable.
