What Height Rings Are Right for Your 50mm Scope? A Comprehensive Guide
Choosing the right height rings for your 50mm scope is crucial for optimal eye relief, comfortable shooting, and proper scope alignment. Getting it wrong can lead to frustration and even injury. This guide will help you determine the perfect ring height for your specific setup.
Understanding Scope Ring Height
Scope rings are measured by their height, typically in inches or millimeters. This measurement refers to the vertical distance between the top of the base and the top of the ring. The critical factor is the clearance these rings provide between the scope's objective lens and the barrel of your firearm. Insufficient clearance can lead to the objective lens impacting the barrel during recoil, potentially damaging both the scope and the rifle.
Factors Influencing Ring Height Selection:
Several factors determine the appropriate ring height for your 50mm scope:
- Scope Diameter: While you've specified a 50mm objective lens, the actual scope tube diameter (typically 1 inch or 30mm) also plays a role. Different tube diameters require different ring sizes.
- Rifle Action and Rail Height: The height of your rifle's scope rail or base significantly impacts the required ring height. Higher rails require lower rings, and vice-versa. Weaver, Picatinny, and other rail systems vary in height.
- Eye Relief: The distance between your eye and the scope's eyepiece is critical for comfortable and safe shooting. Improper ring height can drastically affect eye relief. Too low, and you risk injury; too high, and your sight picture suffers.
- Objective Lens Clearance: This is arguably the most important consideration. Sufficient clearance prevents the objective lens from contacting the barrel during recoil. The required clearance varies depending on the rifle's recoil characteristics and the scope's length.
Determining the Right Height:
There's no single "correct" height for 50mm scope rings. The ideal height depends on the interplay of the factors listed above. Here's a systematic approach:
- Measure Your Rail Height: Use a caliper or ruler to precisely measure the height of your rifle's scope rail or base above the barrel.
- Check Your Scope's Specifications: Consult your scope's manual to determine its tube diameter and the recommended clearance between the objective lens and the barrel.
- Consider Recoil: High-recoil rifles necessitate greater clearance than lower-recoil rifles.
- Start with Medium Rings: If unsure, it's generally safer to start with medium-height rings. You can always adjust later.
- Test and Adjust: Once mounted, ensure sufficient clearance and comfortable eye relief. If needed, switch to higher or lower rings.
Warning Signs of Incorrect Ring Height:
- Objective Lens Contact: If the objective lens touches the barrel, your rings are too low.
- Uncomfortable Eye Relief: If your eye is too close or too far from the eyepiece, your rings may be incorrectly positioned.
- Scope Wobble: Loose rings indicate improper mounting or incorrect height selection.
Conclusion:
Selecting the appropriate ring height for your 50mm scope is crucial for safe and enjoyable shooting. By carefully considering the factors above and following a systematic approach, you can ensure optimal performance and prevent potential damage to your equipment. Remember, safety should always be your top priority. If you're unsure, consulting with a gunsmith is always recommended.
