My Buying Guides on Viridian Rfx15 Green Dot
When I decided to invest in the Viridian Rfx15 Green Dot, I wanted to make sure I understood everything about it before making a purchase. Here’s my personal buying guide based on my research and experience, which I hope will help you decide if this laser sight is right for you.
What Is the Viridian Rfx15 Green Dot?
The Viridian Rfx15 is a compact red or green dot laser sight designed specifically for the Springfield XD(M) 4.5″ and 5.25″ pistols. The green dot version is particularly popular because green lasers are more visible in daylight compared to red lasers. I found that this feature really improves aiming accuracy, especially in bright outdoor conditions.
Key Features I Considered
- Brightness and Visibility: The green dot is bright and crisp, which made it easy for me to acquire targets quickly.
- Durability: The Rfx15 is built tough with an aluminum housing that feels solid and weather-resistant. This gave me confidence that it would hold up well in different environments.
- Battery Life: It runs on a single CR123 battery, and Viridian claims long battery life. From my experience, the battery lasted quite a while during regular use.
- Activation Method: It has an ambidextrous pressure switch that activates the laser automatically when gripping the firearm. This hands-free operation felt natural and enhanced my shooting experience.
- Installation: The Rfx15 mounts directly to the rail of the Springfield XD(M) without needing tools or gunsmithing, which made setup quick and easy for me.
Why I Chose the Green Dot Over Red
I opted for the green dot because green lasers are more visible to the human eye, particularly in daylight or bright conditions. If you often shoot outdoors or in bright environments, the green dot offers a clear advantage. However, red lasers tend to be cheaper and may be sufficient for indoor or low-light use.
What to Look for Before Buying
- Compatibility: Make sure your firearm model matches the Rfx15 design. It is tailored for Springfield XD(M) 4.5″ and 5.25″ pistols only.
- Laser Color: Decide between green or red based on your typical shooting environment and budget.
- Durability Needs: If you plan to use the laser in rugged conditions, check for weather resistance and build quality.
- Ease of Use: Consider if the activation method suits your grip style and shooting preferences.
- Price: The Viridian Rfx15 Green Dot is an investment; compare prices and look for bundles or discounts.
My Final Thoughts
After using the Viridian Rfx15 Green Dot, I can say it significantly improved my target acquisition and shooting confidence. The green laser is bright and reliable, and the unit’s build quality is excellent. If you have a compatible Springfield XD(M) pistol and want a high-quality laser sight that’s easy to use and durable, I highly recommend considering the Rfx15 Green Dot.
I hope my guide helps you make an informed decision! If you have more questions or want to know about my shooting experience with it, feel free to ask.
