Factors To Consider When Buying The Best Red Dots for Glock 47 MOS
Reticle Size and Clarity
The size of the red dot reticle plays a crucial role in accuracy and target acquisition speed. A smaller dot, typically around 3 MOA, allows for precise aiming at longer distances, while a larger dot, such as 6 MOA or 8 MOA, is easier to pick up quickly for close-range engagements. The clarity of the dot is also important—some sights produce crisp, well-defined reticles, while others may have slight distortion or starburst effects depending on the quality of the emitter and lens coatings.
Brightness Settings and Adjustability
A good red dot sight should offer a range of brightness settings to accommodate different lighting conditions. Automatic brightness adjustment can be useful, as it adapts to ambient light, but manual settings allow for more precise control. Night vision compatibility may also be an important feature for those who use night vision equipment. A daylight-bright setting is essential for maintaining visibility in bright outdoor environments.
Battery Life and Accessibility
Battery longevity is a key factor, as red dots rely on continuous power to function. Some models can last thousands of hours on a single battery, while others may require more frequent changes. The battery compartment design also matters—top or side-loading compartments allow for easy replacement without removing the optic, ensuring the sight remains zeroed. Additionally, some optics feature auto-shutoff or motion-activated technology to preserve battery life.
Durability and Build Quality
The construction of the red dot sight determines its ability to withstand recoil, harsh weather conditions, and rough handling. Materials such as 7075 aluminum provide excellent durability while keeping the optic lightweight. A shockproof and waterproof design ensures reliability in different environments, making the sight suitable for both everyday carry and duty use. Anodized finishes add an extra layer of protection against scratches and corrosion.
Mounting Compatibility and Footprint
Choosing a red dot with the correct mounting footprint is essential for easy installation on a Glock 47 MOS. Some optics come with dedicated adapter plates, while others may require aftermarket solutions. A sight that offers multiple mounting options, including direct mounting to the MOS system or compatibility with standard Picatinny rails, provides greater flexibility. The height of the optic should also be considered to ensure proper co-witnessing with backup iron sights if needed.
Parallax and Eye Relief
A good red dot sight should be parallax-free, meaning the point of aim remains accurate even if the shooter’s eye is slightly off-center. This allows for faster target acquisition and increased accuracy under dynamic conditions. Unlimited eye relief ensures that the sight can be used comfortably at any distance from the shooter’s eye, making it ideal for handguns where quick sight alignment is necessary.
Ease of Use and Controls
The user interface of a red dot sight should be intuitive, with easily accessible brightness controls and adjustment turrets. Push-button controls are often preferred for their simplicity, while dial-based adjustments may offer finer control. Windage and elevation adjustments should be precise and easy to set, with audible or tactile clicks for quick zeroing. Features like motion activation or auto-off timers enhance convenience, especially for everyday carry or duty use.
Weight and Size
Since handguns are designed for maneuverability, a red dot sight should be lightweight and compact to avoid adding unnecessary bulk. Heavier optics can affect the balance of the firearm, making it less comfortable to carry and shoot. A slim, low-profile design ensures the sight does not interfere with holstering or handling, while still providing a large enough lens for quick target acquisition.
