Scope Mount and Ring Height Principles Advisor

Explains mount types (one-piece, two-piece, cantilever), ring height for proper cheek weld, eye alignment, and clearance over barrel/action for hunting and target rifles.

‍

This tool is meant for shooters mounting scopes who want proper height and position for comfort and accuracy.

‍

The inputs cover rifle action type, current mount issue, ring height preference, primary activity, stock type, experience level, and objective lens size, explaining mount types, ring height for weld/alignment/clearance. These choices suit bolt action or AR platforms. This tool teaches mounting principles but proper torque requires tools.

Mount Fundamentals

When selecting a scope mount and rings for your bolt-action rifle, it’s essential to understand the basic mount types and their functions:

1. One-Piece Mounts: These provide a stable platform for the scope and often reduce the chance of misalignment.
2. Two-Piece Mounts: Consist of separate rings and bases. They allow for more flexibility in height and positioning but may require more careful alignment.
3. Quick-Detach Mounts: Allow for easy removal and reattachment of the scope without losing zero, useful for varying shooting conditions.

Key Principles:

• Alignment: Proper alignment is crucial to maintain accuracy and prevent scope damage.
• Height: The height of the rings affects both the cheek weld and the line of sight.

Ring Height Principles

For your specific needs, here’s how to determine the appropriate ring height:

1. Objective Lens Size: Since you have a 40-50mm objective lens, low rings are generally suitable. However, the exact height may depend on:
   • The barrel contour
   • The stock design
2. Cheek Weld: A poor cheek weld can affect your shooting accuracy. When using low rings:
   • Ensure your cheek naturally rests on the stock when you look through the scope.
   • If necessary, you may need to use a cheek riser to improve comfort and alignment.
3. Eye Relief: Ensure that the scope’s eye relief is compatible with your shooting position. For target shooting, you may want to adjust the scope further back to avoid a harsh recoil impact.

Example:

• For a 40mm objective lens, low rings (typically around 0.75 inches to 1 inch in height) should suffice, provided they allow the scope to clear the barrel while giving you a proper cheek weld.

Installation Tips

To ensure a successful installation of your scope mount and rings, follow these guidelines:

1. Alignment Check: Before tightening, ensure the scope is perfectly aligned with the barrel. Use a level to confirm the scope's reticle is horizontal.
2. Torquing: Follow the manufacturer's recommended torque specifications for ring screws. A common torque setting is 15-20 inch-pounds. This helps prevent overtightening, which can damage the scope.
3. Use Proper Tools: Utilize a torque wrench for accuracy and avoid slipping or rounding off screws.
4. Final Check: After installation, double-check the alignment and ring tightness. Test with a few shots to ensure the scope holds zero.

General Principles:

• Always prioritize proper mounting to prevent damage to your scope, and ensure a stable platform for optimal accuracy.
