Top 7 Best RMR for a Glock

1. Trijicon RMR Type 2 6.5 MOA – Best for Professionals

The Trijicon RMR Type 2 6.5 MOA, a highly acclaimed red dot sight, is known for precision, offering a blend of robustness, versatility, and elegance in one package.

Durability and Construction: The sight’s extraordinary durability is evident in its 7075-T6 aluminum construction, which follows mil-spec standards. 

With a patented design that absorbs impacts and diverts stresses away from the lens, the construction ensures that it stays intact even after harsh treatment. 

Its Shockproofing capabilities add to the ruggedness, making it a dependable choice on a Glock.

Brightness Controls: The eight adjustable brightness levels, including an automatic mode, tailor the LED illumination to suit the shooter’s surroundings. 

This functionality ensures that the red dot is always observable, no matter the lighting condition. 

One minor problem is that the automatic brightness adjustment might not be sufficient in full sunlight, though this doesn’t detract significantly from its overall performance.

Ease of Use and Installation: The lightweight design of 1 oz and solid construction simplify the installation process, making it a suitable fit for Glocks. 

The ease of mounting and adjusting allows even those who are new to optics to install it without any hitches. This accessibility sets it apart from more complex models in the market.

Reticle and Targeting: The larger 6.5 MOA reticle stands out by allowing users to locate the dot quickly. 

This feature is best for close-quarter engagements and those with vision problems. 

Quick to pick up and easy to track during fast shots or multiple strings of fire, the reticle aids in both speedy and precise shots.

The Trijicon RMR 3.25 MOA is crafted for precision, featuring a multitude of brightness settings, high-grade lens clarity, extended battery life, and rugged durability, suitable for Glocks.

Brightness Setting: One of the sight’s standout features is its range of 8 illuminance options tailored to the shooter’s environment. 

Comprising the first 2 settings for night vision and 6 more for bright to low-light conditions, this functionality adds an impressive layer of adaptability. 

The RMR 3.25 MOA model also hosts an auto-illumination mode that adjusts the reticle’s brightness according to the ambient lighting, allowing seamless transitioning without manual alteration.

Lens And Glass Clarity: The RMR 3.25 MOA lens is fabricated from high-quality, crisp glass, offering a broad field of view devoid of obstructions. 

A specialized coating reduces glare and maintains a clear image, even under powerful sunlight. 

Moreover, the absence of parallax means that the shooter’s point of aim remains steadfast, ensuring an accurate and consistent aim.

Excellent Battery: This model is energized by a CR2032 lithium battery, easily accessible by removing the top battery cover. 

Depending on the brightness level, the battery can last up to four years on the lowest setting or as little as 25 days on the highest. 

The sight’s automatic illuminance adjustment function and sleep mode contribute to effective battery management, assuring reliable operation without constant monitoring.

Size of Reticle: The 3.25 MOA red dot reticle presents the perfect equilibrium for various shooting scenarios. 

Large enough to be readily seen for close-quarters targeting but also sufficiently small for precision at longer distances, it provides flexibility and versatility to the shooter.

Best Durability: The Trijicon RMR Type 2’s construction embodies resilience and ruggedness, being waterproof up to 66ft. 

Whether it’s rainy or snowy conditions, this sight’s sturdy housing and patented force-deflective design ensure that it remains an unfaltering, reliable optic for any scenario, whether military, law enforcement, or recreational use.

Throughout my testing, it was evident that the manufacturers didn’t compromise on the 

materials’ quality. Knowing that this sight could handle tough conditions without failing gave me peace of mind.

Dual-Illuminated Option: The dual-illuminated option is a groundbreaking feature in this RMR. Combining a tritium-phosphor lamp with fiber optics provides exceptional visibility in low-light conditions. 

The tritium offers a soft glow, whereas the fiber optic adjusts automatically as conditions brighten, maintaining excellent illumination. 

I found this combination to be highly efficient, with the sight adapting seamlessly to changing lighting conditions. 

True-Color, Multi-Coated Lens: Another standout feature that caught my attention was the true-color, multi-coated lens.
