Choosing the right red dot mount for your rifle is crucial for accuracy and reliability. The Trijicon RMR (Ruggedized Miniature Reflex sight) is a popular choice for its durability and performance, but finding the optimal mount can be challenging. This guide explores various RMR red dot mounts for rifles, helping you select the perfect one for your needs and firearm.
Understanding RMR Mounts: Key Considerations
Before diving into specific mounts, let's understand the key factors influencing your choice:
1. Height Over Bore (HOB):
This refers to the vertical distance between the center of your bore (the barrel's interior) and the center of your RMR's optic. Proper HOB is essential for accurate zeroing and point-of-impact consistency. Too low, and your shots will consistently land low; too high, and they'll land high. The ideal HOB depends on your rifle, optic, and shooting style. Many manufacturers provide specifications indicating the HOB of their mounts.
2. Mounting System:
Different mounts utilize different attachment methods. Common systems include:
- Picatinny/Weaver Rails: The most prevalent system, offering a standardized interface for a wide range of optics and accessories. Ensure your rifle's rail is compatible with your chosen mount.
- Direct-to-Slide Mounts (for pistols): While not directly relevant to rifles, it's worth noting that RMRs are also popular on pistols, using specialized mounts for direct attachment to the slide.
3. Material and Durability:
The mount's material significantly impacts its strength and longevity. High-quality mounts are typically constructed from aircraft-grade aluminum or steel, providing superior durability and resistance to wear and tear. Look for mounts that are specifically designed to withstand the recoil of your rifle caliber.
4. Return-to-Zero Capabilities:
Some mounts boast superior return-to-zero features, meaning that after removing and remounting the optic, the zero remains consistent. This is beneficial for maintaining accuracy and reducing the need for re-zeroing.
Types of RMR Mounts for Rifles
The market offers a diverse range of RMR mounts, categorized primarily by their height and mounting method:
1. Low-Profile Mounts:
These keep the RMR close to the bore, offering a lower profile and potentially improved cheek weld. However, they might necessitate lower-mounted iron sights for co-witnessing.
2. Medium-Height Mounts:
These provide a balance between low profile and sufficient clearance, often allowing for co-witnessing with taller iron sights.
3. High-Profile Mounts:
These offer maximum clearance, ideal for users who prioritize co-witnessing with their iron sights, or who require a higher sight picture for better visibility.
Choosing the Right RMR Mount: A Step-by-Step Guide
- Identify your rifle's rail type: Ensure compatibility with Picatinny or Weaver rails.
- Determine your desired HOB: Consider your rifle, optic, and shooting style. Manufacturers' specifications can guide you.
- Assess your budget: Quality mounts vary in price. Invest in a reputable brand to ensure durability and accuracy.
- Consider co-witnessing requirements: Determine if you need absolute co-witness, lower 1/3 co-witness, or no co-witness.
- Read reviews: Research different mounts and read user reviews before purchasing. This will provide valuable insights into real-world performance and durability.
Maintaining Your RMR Mount
Proper maintenance is crucial for the long-term performance of your RMR mount. Regularly inspect the mount for any signs of wear, damage, or looseness. Tighten screws as needed, and clean the mount periodically to remove dirt and debris. Lubrication of moving parts might be beneficial, depending on the mount design.
By carefully considering these factors and following this guide, you can confidently select the optimal RMR red dot mount for your rifle, ensuring accurate, reliable, and enjoyable shooting experiences. Remember, consulting with experienced shooters or firearms professionals can offer valuable personalized recommendations.
