Choosing the right scope mount is crucial for long-range shooting, and understanding the benefits of a 20 MOA (Minutes of Angle) mount is key for precision. This comprehensive guide will delve into the specifics of 20 MOA scope mounts, explaining their function, advantages, and how to choose the right one for your rifle.
What is a 20 MOA Scope Mount?
A 20 MOA scope mount is a mounting system that incorporates a 20-minute angle of elevation into its design. This built-in cant allows you to adjust your scope's point of impact more easily at longer ranges. Think of it as a head start on your elevation adjustments. Instead of starting at zero and having to crank your scope's elevation turret significantly upwards to find your zero at distance, the 20 MOA base gives you that initial adjustment built right in.
Why Choose a 20 MOA Scope Mount?
Several advantages make 20 MOA mounts a preferred choice for long-range shooting:
Increased Adjustment Range:
The most significant benefit is the extended elevation range. With a standard mount, reaching optimal zero at extreme distances often requires maximal upward adjustment, potentially exceeding your scope's mechanical limits. A 20 MOA base provides extra upward travel, preventing you from running out of elevation adjustment before finding the perfect zero. This is particularly important when using high-powered optics for extremely long-range shooting.
Reduced Turret Travel:
Using a 20 MOA mount means less dialing on your scope's elevation turret to achieve zero. This not only simplifies the zeroing process but also minimizes the accumulation of errors caused by repeatedly turning the turret. It leads to greater precision and consistency in long-range shooting.
Maximizing Scope's Capabilities:
Many scopes have limited elevation adjustment ranges. By using a 20 MOA mount, you essentially extend the usable elevation range of your scope, allowing you to fully exploit its capabilities.
When Should You Use a 20 MOA Mount?
A 20 MOA mount is an excellent choice for these scenarios:
- Long-range shooting: If you're engaging targets at distances exceeding 600 yards, a 20 MOA mount is highly recommended.
- High-powered scopes: When using scopes with limited vertical adjustment, a 20 MOA base helps extend the range of adjustments.
- Extreme elevation changes: In mountainous or hilly terrains where significant elevation adjustments are needed, a 20 MOA base helps keep you in the operational range of the scope.
Selecting the Right 20 MOA Scope Mount: Key Considerations
Choosing the right 20 MOA mount involves careful consideration of several factors:
- Material: High-quality mounts are usually made from aircraft-grade aluminum for strength and durability.
- Construction: Look for solid construction, precise machining, and a robust design to ensure accuracy and reliability.
- Compatibility: Verify that the mount is compatible with both your rifle's receiver and your scope's tube diameter.
- Height: Choose a mount height that provides adequate clearance for your scope and rings, ensuring the scope does not interfere with the action of your rifle.
- Manufacturer Reputation: Reputable manufacturers often produce mounts that exceed industry standards for accuracy and longevity.
Conclusion: Optimizing Your Long-Range Shooting with a 20 MOA Mount
A 20 MOA scope mount is a valuable tool for long-range shooters. Its incorporation of built-in elevation greatly simplifies the zeroing process, maximizes the scope's capabilities, and improves overall accuracy. By carefully considering the factors outlined above, you can choose a 20 MOA mount that enhances your long-range shooting experience and helps you achieve your best results. Remember to always practice safe firearm handling and follow all applicable laws and regulations.
