Trijicon MRO: When Only the Best Will Do
After extended testing across multiple platforms, the Trijicon MRO (Miniature Rifle Optic) has proven why it’s trusted by military and law enforcement. This isn’t just another red dot—it’s a precision instrument designed to perform when failure isn’t an option. Made in the USA.

- Dimensions (L×W×H): 2.6 × 1.7 × 2.0 in

Optical Performance
The 25 mm objective provides a generous field of view for fast target acquisition. Glass is clear with excellent transmission. Parallax is minimal at distance (as with quality red dots); we saw no meaningful POI shift at practical carbine ranges.
Construction & Sealing
A forged 7075‑T6 aluminum housing and recessed objective protect the optic from impacts. Electronics are sealed, and the unit is waterproof to 100 ft / 30 m.
Brightness & Power
- 8 settings: 1–2 NV, 3–4 low light/indoor, 5–6 daylight, 7–8 very bright conditions
- No auto‑off by design—always ready. Long battery life makes this practical.
- Top battery compartment lets you swap cells without removing the optic.
Mounting & Zero Retention
Footprint: The MRO uses a dedicated MRO footprint (not a generic 30 mm ring). Trijicon’s AC32068 (full co‑witness) and lower‑1/3 options are common, and many retailers sell the optic with or without a mount. Verify bundle contents before buying. A quality torque wrench helps (e.g., 35 in‑lbs for cross‑bolts if specified by your mount).
Pros & Cons
✅ Pros
- Wide, forgiving viewing window
- Forged aluminum housing
- Long battery life; always‑on friendly
- Clear glass and strong light transmission
- Made in USA, trusted by professionals
❌ Cons
- Higher price than feature‑rich budget options
- Slight blue tint on some units
- No auto‑off; limited brightness memory
Competitor Comparison
vs. Aimpoint T-2: T-2 is smaller with legendary battery life; MRO offers a larger window and better value.
vs. EOTech EXPS3: Holographic tech and unique reticles vs. LED simplicity and much longer battery life on the MRO.
vs. Holosun HS515CM: Holosun packs features (solar, shake‑awake) at lower cost; MRO wins on construction pedigree and pro adoption.
Warranty & Support
Trijicon backs the MRO with a limited lifetime warranty on the housing/optical system; the electronics are typically covered for ~5 years from date of manufacture. Service is responsive and knowledgeable in our experience.
Final Verdict
The MRO is a premium, duty‑ready red dot with a wide window and serious durability. It costs more than budget sights, but delivers confidence that’s hard to price.
Rating: 4.8/5 — almost flawless; price is the only real downside.
