1. What is a Rifle Sight Height Calculator?

Definition: This calculator determines the sight height by calculating the difference between barrel height and scope height.

Purpose: It helps shooters and gunsmiths properly align their scopes with rifle barrels for accurate shooting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( SH \) — Sight height (meters, m)
• \( H_b \) — Barrel height (meters, m)
• \( H_s \) — Scope height (meters, m)

Explanation: The scope height is subtracted from the barrel height to determine the vertical offset between the two.

3. Importance of Sight Height Calculation

Details: Proper sight height calculation ensures accurate bullet trajectory and proper scope alignment with the barrel.

4. Using the Calculator

Tips: Enter the barrel height and scope height in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is sight height important?
A: Sight height affects bullet trajectory and point of impact, especially at different distances.

Q2: How do I measure barrel height?
A: Measure from the center of the bore to the top of the barrel or action rail.

Q3: How do I measure scope height?
A: Measure from the center of the scope tube to the base where it mounts to the rifle.

Q4: What's a typical sight height for rifles?
A: Most rifles have sight heights between 1.5-3 inches (0.038-0.076 meters), depending on mounting system.

Q5: Does this account for scope cant angle?
A: No, this calculates vertical height difference only. For angled mounts, additional calculations are needed.
