Trijicon MRO HD Circle Dot No Mount Superb Rifle Optic

Description

The Trijicon MRO HD Circle Dot No Mount is Trijicon’s high-definition Miniature Rifle Optic with a 68 MOA circle and 2 MOA dot, sold as the sight only. It is a top choice for defensive carbines where a fast circle reticle matters.

Trijicon MRO HD Circle Dot No Mount Overview

Trijicon part MRO-C-2200050 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

No mount is included. The MRO uses its own mounting pattern, and a wide range of mounts are made for it, including Trijicon levered quick-release mounts and premium options from companies like Geissele. That lets you choose the exact height and cantilever for your rifle.

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. With no mount included, plan to buy an MRO-pattern mount at the height you prefer.

Ordering and Transfer

When you order a firearm from MAG5 Firearms, we ship it to the licensed dealer you choose. Your dealer completes the ATF Form 4473 and the background check, and may charge a transfer fee. Local buyers can complete the transfer at our shop. Bring a valid ID, and check your state waiting period before you plan a hunt or a range trip.

Safe Storage

Store the firearm unloaded in a locked safe or case, with ammunition kept separately. A cable lock or trigger lock is a good backup, especially in a home with children or visitors. Keep the original box and paperwork, and record the serial number in a safe place in case the gun is ever lost or stolen.

Your First Range Trip

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.
