Trijicon MRO  

Newer to the market than the AimPoint PRO, the Trijicon MRO (Miniature Rifle Optic) can be mounted to your rifle for faster target acquisition and absolute dependability.

One big difference between the two sights is the Trijicon MRO has a larger objective lens diameter providing wider viewing, a better field of view, and less tunnel vision. It also allows for fast target engagement – especially from non-standard shooting positions.

In addition, it is half the weight and size of the AimPoint PRO. It also has the convenience of an ambidextrous illumination knob on the top. The Trijicon MRO is a sealed miniature reflex sight intended for use on rifles, carbines and shotguns to provide fast target acquisition.

Made in the USA, it is fully sealed, waterproof, made with hard anodized forged 7075-T6 housing and is considered the ultimate mini reflex sight on the market.

Because the sight can be rifle or shotgun mounted, is fully ruggedized, waterproof and enables fast target acquisition, especially from non-standard shooting positions, it is trusted by special operations forces around the world and is also a favorite among turkey hunters.

Regarding the specs, the front lens coating seems to block out the sun glare pretty well. The optic has nice adjustment turrets that don’t require removing of any caps to operate. MOA adjustments are done in solid clicks. Large and well-marked brightness adjustment are in the shooter’s line of sight for fast adjustment. However, a big difference between this sight and the AimPoint PRO is that it doesn’t come with any covers for both the front and rear lens.

The elevation and windage dials have an audible and physical click with each turn.  It is waterproof to 30 meters (versus the AimPoint PRO is waterproof to 45 meters) and temperature rated to -60 to +160F. Said a customer in a review on Amazon, “So you can freeze it in a block of ice, thaw it out and it should still be working.”

The battery is included and comes pre-installed inside the optic. It is rated to run for 5 years of continuous operation at brightness level ‘3’ on a single battery, which customer stated is, “awesome” and “outstanding” (the AimPoint PRO has a 3-year battery life).

On Amazon, there are 259 reviews, 72 percent are 5-star. The sharpness and clarity of the reticle is strong and customers like the legendary Trijicon toughness (“construction is robust”), a lifetime warranty, increased FOV, a well-thought-out ergonomic control setup. Said one customer, “5 stars in my book!” At around $400, the price is carries a lot of value, and is comparable to the AimPoint PRO.

Aimpoint PRO

In the world of firearms, “boringly reliable” is a good attribute. The AimPoint PRO (12841) Patrol Rifle Optic, launched in 2011, has proven itself again and again. It was designed with the feedback from an elite group of professionals, and unlike the Trijicon MRO, the lens covers and mount are already included.

The PRO sight contains a QRP2 mount and a standard AR15 spacer that can be removed. While it is bigger and heavier than the Trijicon MRO, the all-in-one features make it complete and ready to mount, and you can customize your sight with other accessories and mounts.

Additionally, the PRO is always on and has a 3-year battery life, removing the need to switch it on prior to use (note that the Trijicon MRO has a 5-year battery life). It has a 2-minute of angle red dot for accurate target engagement at all distances. In-service date and battery change date reminders make inventory tracking and maintenance easy.  It has enhanced speed on target and increased first shot hit probability when compared to iron sights and magnified scopes. It is compatible with all generations of night vision devices and may be used with all Aimpoint Magnifiers and Concealed Engagement unit.

With hard anodized aluminium alloy housing, the Aimport PRO is rugged enough for real world conditions and is waterproof up to 150 feet. The threaded front lens opening allows the use of screw-in antireflection device (ARD). The front and rear flip covers keep lenses clean, a big difference compared to the Trijicon MRO which does not come with lens covers. A transparent rear flip cover allows use of the sight (with both eyes open) even with both covers closed in an emergency. It is designed for sudden quick shots when you don’t have the time to flip up the covers. According to one user, it is quite accurate in a pinch.

Battery and adjustment cap retainer straps conveniently keep everything together. The PRO comes with a modular mount set up for use on flat-top AR15, M4 Carbine and M16 rifles (adapters are available for carry handle mounting). You can snap the QRP2 rail grabber mount knob three times for a perfect mount, which will not deform your rail like many other mounts. The recessed lens openings helps prevent against impact damage, fingerprints and scratches.  

This sight is made in Sweden (unlike the Trijicon MRO which is made in the U.S.) and has 522 reviews on Amazon with 88 percent of those reviews 5 star. Regarding the specs, customers like the sharp, crisp and adjustable reticle. The tension knob is highly effective, although one reviewer found it bulky. Customers also like the red dot optic, calling it “excellent”. The settings can be fine-tuned for the most desirable sight picture either day or night.

Referred to as “an awesome value,” it is very rugged, with a positive feel. The unit seems well made, solid, and customers like the long battery life. At around $400, the price is comparable to the Trijicon MRO.

Summary and Recommendations

Both the AimPoint PRO and Trijicon MRO are comparable in price, and each one brings solid features. It really comes down to what features are most important to you.

The battery life for both sights is strong. However, the Trijicon MRO is longer. The MRO also has a larger aperture and tapered light path to maximize the viewing area and allow for faster target acquisition and superior situational awareness. The MRO is also half the size and weight of the AimPoint PRO. Keep in mind that a separate mount will cost around $90, and many customers recommend a quality QDS mount (which come standard on the AimPoint PRO).

Both models are also compatible with night vision devices, and both have great image quality.


If you prefer a product that has been proven by the test of time, then the Aimpoint Pro is your sight.  It is highly durable and reliable, and the lens covers are a great addition that will keep the lenses clean and protected.

However, if you need something more compact, Trijicon MRO is a solid choice. The wider field of view is also an important consideration.
