Trijicon MRO HD Circle Dot Lower 1/3 Superb Carbine Optic

Description

The Trijicon MRO HD Circle Dot Lower 1/3 pairs Trijicon’s MRO HD circle-dot red dot with a lower 1/3 co-witness mount, the most popular height for AR-15 carbines. It is a ready-to-run defensive rifle optic.

Trijicon MRO HD Circle Dot Lower 1/3 Overview

Trijicon part MRO-C-2200053 is the MRO HD, the high-definition version of Trijicon’s Miniature Rifle Optic with a selectable circle-dot reticle. The 25mm objective and short tube give the MRO one of the widest fields of view of any micro red dot, which makes it easy to find the dot with both eyes open.

The HD Reticle

The MRO HD projects a 68 MOA circle around a 2 MOA center dot, and you can switch between the full reticle and the dot alone. The large circle is extremely fast to pick up at close range and helps with movers, while the dot handles precise shots at distance. The HD version also adds improved glass and coatings over the original MRO.

Power and Brightness

The HD uses a single coin cell with 16 brightness settings, 4 of them for night vision devices. Trijicon rates battery life at about 2.5 years with the dot alone at setting 5 of 8, but only about 75 days with the full circle reticle lit, so most users run the circle for defense and the dot for range work, or change the battery on a schedule.

Mounting

This package includes a lower 1/3 co-witness mount, the most popular height for AR-15 style rifles. Standard iron sights sit in the bottom third of the window, visible as a backup without cluttering the view, and the head position suits most shooters.

Magnifier and Night Vision

The MRO HD works with Trijicon’s 3x magnifier and night vision devices. Behind a magnifier, many shooters switch to the dot-only reticle so the large circle does not cover the target.

Built Like a Trijicon

The MRO SD uses a forged 7075 aluminum housing, sealed and filled with dry nitrogen, and is rated submersible to 100 feet. Capless, sub-flush adjusters move the dot 1/2 MOA per click and cannot be bumped or lose caps. Eight brightness settings include 4 for night vision devices, the top setting is super bright for sunny days. The housing has a matte black finish. The 68 MOA circle drains the battery much faster than the dot alone, so keep a spare cell handy or use dot-only for range days.

Mount your optic, bore sight it, then fire your first groups at 25 yards before moving to 100. Let the barrel cool between strings, and record your zero and the load you used. Wear eye and ear protection, keep the muzzle in a safe direction, and clean the bore when you get home.
