Easy and Fast: The Trijicon RMR Dual-Illuminated Sight

Last Updated on January 5, 2023.

The vast array of sights available can be pretty overwhelming, even if you do know what terms like MOA and reticle mean. Trying to decide between manufacturers, price points, and features get exhausting after a while, often leading to just buying the one with the lowest price and calling it good.

Thankfully, Trijicon puts out consistently reliable products, so regardless of what you’re looking to do, there’s probably a product for it, and it’ll do what it says it will. The Ruggedized Miniature Reflex, or RMR, product line falls into that category as well, and the dual-illuminated model especially.

Scope Review and Breakdown


The big thing about the Dual-Illuminated is, well, the dual illumination. It’s lighted by a tritium-phosphor lamp, with fiber optics that adjust the brightness for various lighting conditions, so no batteries are needed even in overcast weather.

The lack of dependence on battery power means no last-minute equipment failure and offers lifetime operation without added cost – an excellent selling point. Combined with the limited lifetime warranty, that’s a fantastic combination. For those who pay attention to such things, it’s also non-electronic and therefore impervious to an EMP.

Built of forged 7075-T6 aircraft-grade aluminum like the best-selling ACOG, this product is tough and can take whatever you put it through. The extensive line of more than 25 mounts and accessories means it can work with whatever you put it on as well, in a variety of positions.

It is small, with a low-profile that can be mounted alone or on an ACOG. You can even use your iron models to co-witness since it won’t get in the way. The shape is built to absorb the recoil as well, and direct the impact stress somewhere other than the glass itself.

Windage and elevation adjustments are done with audible – but not too audible – clicks and can be accomplished with gloves on. All in all, it’s easily operated with minimal fuss and sports a few impressive features that push it to the top of the pile.


  • 1X magnification, with 9.0 MOA dot
  • 7075-T6 housing
  • Lightweight at 1.2 oz
  • Length of 45mm
  • Adjustment of 1 click/1 inch/100 yds
  • Price point: Over $500

Ease of Use and Reliability

There’s not much to say about ease of use, simply because it’s that easy. It has a flat base that stabilizes it regardless of what you mount it on or where it goes. It screws into the mount and can be placed at the standard clock positions of 11, 12, or 1.

Battery Life

What battery? The fiber optics and tritium make this red dot a very bright-running optic without requiring battery power. That means no matter how long it’s been sitting there, it will still do its job.


It can run the gamut concerning price; much of the cost can end up coming from the mount. There are substantial variations in the rate of the mounts but expect to pay somewhere in the $400-650 range. Depending on the vendor, you may be able to get a coupon or other offer that drops the price.

Who is this Scope for?

Type of Shooter

The sight can be used alone, with a magnification scope, or with iron sights, so it is equally at home in close quarters or a long-range environment. Whether you’re looking for faster target acquisition speed or merely building accuracy, it will do what it promises.

Type of Gun

The company says the RMR was designed to work on a weapon of any style or caliber, and the wide variety of mounts for a host of different firearms shows they mean it. It can be run on a shotgun for home defense, a rifle for long range or hunting work, or a pistol for everyday carry.

Final Verdict

Trijicon RMR Dual-Illuminated Sight

The RMR is a simple piece of equipment that mounts to just about any firearm and provides a dot that can be easily seen in a variety of lighting. While it is subject to dot washout if you’re also running light on your weapon, that’s a standard issue with red dots that can be mitigated with suppressor sights.

The cost can be prohibitive – this isn’t a cheap product. With a price point that can exceed $500 with the mount, depending on how much you paid for the firearm you put it on, you might pay more for the RMR and corresponding mount than you did for the gun. That being said, it’s worth the money; it’s light, versatile, and it’ll do what you need it to do. More importantly, it’ll do it for a very long time. With the RMR, you get what you pay for – arguably the best RMR on the market.

Other Options Worth Looking At

If you decide that the Trijicon Dual Illumination sight is a bit too far out of your price range, you might try the Primary Arms Micro Red Dot. It’s a waterproof 2 MOA dot with a price point under $100 and a battery life of 1,000 hours.

If battery life is non-negotiable, the Holosun Open Reflex is a holographic unit that uses solar energy as its primary power source with a battery only used for backup. Regarding price, it runs between the Primary Arms model and the RMR.
