The fact that ohhunt has improved this aspect from their older version shows a commitment to providing a secure and dependable mounting platform. For me, this means less time adjusting and more confidence in my equipment’s performance during critical moments.

Buying Guide for RMR to Picatinny Mount

Understanding What an RMR to Picatinny Mount Is

When I first started looking for an RMR to Picatinny mount, I wanted to make sure I understood exactly what it does. Essentially, this mount allows you to attach a Trijicon RMR (Ruggedized Miniature Reflex) sight to a Picatinny rail system. This is crucial if your firearm has a Picatinny rail but the RMR isn’t designed to fit directly. Knowing this helped me narrow down my options significantly.

Compatibility with Your RMR and Firearm

One of the first things I checked was whether the mount was compatible with my specific RMR model and the Picatinny rail on my firearm. Not all mounts fit every RMR, so I made sure to verify the dimensions and attachment points. Also, the Picatinny rail on my gun needed to be standard size and free of obstructions to ensure a proper fit.

Material and Durability

I wanted a mount that could handle recoil and rough use, so I looked for mounts made from strong materials like aircraft-grade aluminum or steel. A durable mount ensures that my RMR stays securely in place, maintaining zero even after heavy shooting sessions. The finish also mattered to me because it needed to resist rust and wear.

Height and Sight Alignment

Mount height is something I paid close attention to. The mount needs to position the RMR at the correct height so that my eye aligns naturally with the sight. Some mounts raise the optic slightly higher, which can be better or worse depending on your iron sights or other optics on your firearm. I measured and considered how it would affect my shooting stance.

Ease of Installation and Adjustability

I looked for mounts that were easy to install without specialized tools. Some mounts come with integrated screws and a simple tightening system, which made the process straightforward. Additionally, some models offer slight adjustability to fine-tune the position of the RMR, which I found helpful to get the perfect sight picture.

Weight Considerations

Since I carry my firearm for extended periods, the weight of the mount mattered. I preferred a lightweight design that wouldn’t add unnecessary bulk or affect the balance of my gun. Aluminum mounts usually struck a good balance between strength and weight.

Price and Value

I set a budget but also wanted to ensure I wasn’t compromising quality. Sometimes spending a bit more on a well-made mount saved me from headaches down the line. I compared features and read reviews to make sure I was getting good value for my money.

Additional Features

Some mounts offer extra features like anti-slip bases or integrated recoil lugs for added stability. While not essential for everyone, I considered these features as potential benefits depending on my specific needs.

Final Thoughts

Buying an RMR to Picatinny mount was about matching compatibility, durability, and ease of use to my firearm setup. Taking the time to understand these factors helped me make an informed decision that improved my shooting experience.
