Finding the right scope rings is crucial for accurate long-range shooting. A 20 MOA (Minute of Angle) scope ring base provides a significant advantage, especially for shooters tackling longer distances. This guide will explore everything you need to know about 20 MOA scope rings, helping you choose the perfect set for your rifle and shooting style.
Understanding MOA and Its Importance in Long-Range Shooting
Before diving into 20 MOA scope rings, let's clarify what MOA means. MOA stands for Minute of Angle, representing 1/60th of a degree. At 100 yards, 1 MOA equates to approximately 1 inch of group size. This means that a rifle capable of 1 MOA accuracy will produce a group of shots within a 1-inch diameter circle at 100 yards.
At longer ranges, the effect of bullet drop becomes more pronounced. This drop requires significant scope adjustments, often exceeding the standard adjustment range found on many scopes. This is where 20 MOA rings come into play. A 20 MOA base provides an additional 20 minutes of angle of elevation adjustment, effectively extending your scope's adjustment capabilities by roughly 20 inches at 100 yards. This added adjustment range is invaluable for long-range shooting, allowing you to dial in your scope for shots at much greater distances.
Benefits of Using 20 MOA Scope Rings
Several key advantages come with using 20 MOA scope rings:
- Increased Adjustment Range: The primary benefit is the significant increase in vertical adjustment, essential for compensating for bullet drop at long range.
- More Headroom: You have more "headroom" for adjustments, avoiding the need to reach the maximum elevation limits of your scope at moderate ranges.
- Reduced Scope Travel: Minimizes the need to make excessive adjustments, which simplifies your dialing process and can improve accuracy.
- Improved Zeroing Process: Makes zeroing your scope easier, reducing the time it takes to get on target at long range.
- Better Reticle Position: Ensures your reticle is in a better position within the scope’s adjustment range, giving you a better and more useable sight picture for long range shots.
Choosing the Right 20 MOA Scope Rings: Key Considerations
Selecting the appropriate 20 MOA scope rings involves several factors:
- Ring Height: Ring height depends on your scope's diameter and the rifle's action. Too low, and the scope may interfere with the rifle's action; too high, and the scope's clearance may be compromised.
- Material: Rings are typically made of aluminum or steel. Aluminum rings offer a lighter-weight solution, while steel rings provide superior durability.
- Construction: Look for rings with solid construction, avoiding those with flimsy or potentially weak points.
- Compatibility: Ensure the rings are compatible with your scope's tube diameter and your rifle's mounting system.
- Brand Reputation: Invest in high-quality rings from reputable manufacturers. Reputable brands employ precision machining and quality control, guaranteeing proper ring alignment.
Installation and Mounting of 20 MOA Scope Rings
Correct installation is critical to ensure accurate shooting. Improper installation can lead to misalignment and affect accuracy. Follow these steps:
- Prepare the Base: Carefully clean the rifle's receiver where the base will attach.
- Secure the Base: Mount the 20 MOA base securely to the receiver, ensuring proper alignment and tightness.
- Mount the Rings: Attach the rings to the base, making sure they are properly aligned and tightened securely.
- Install the Scope: Carefully mount the scope in the rings, and tighten them securely.
- Check Alignment: Use a bore-sighting tool or proper technique to check the scope's alignment before heading to the range.
