Understanding AR-15 Scope Ring Height: A Comprehensive Guide
When it comes to customizing your AR-15 rifle, one of the most crucial decisions you’ll make is choosing the right scope ring height. The scope ring height directly impacts the overall performance and accuracy of your firearm. In this detailed guide, we’ll delve into the various aspects of AR-15 scope ring height, helping you make an informed decision for your rifle.
What is Scope Ring Height?
Scope ring height refers to the distance between the top of the scope and the top of the rifle’s receiver. This measurement is crucial because it determines the eye relief, which is the distance between your eye and the scope’s lens. The correct scope ring height ensures optimal eye relief, allowing for a comfortable and accurate shooting experience.
Why is Scope Ring Height Important?
Several factors make scope ring height an essential consideration for your AR-15 rifle:
-
Accuracy: The correct scope ring height ensures that the scope is aligned with the rifle’s bore, minimizing parallax and improving accuracy.
-
Comfort: A well-positioned scope ring height provides a comfortable shooting experience, reducing eye strain and fatigue.
-
Adjustability: The scope ring height allows for adjustments in the scope’s position, accommodating different shooting scenarios and preferences.
Types of Scope Ring Heights
There are several types of scope ring heights available for AR-15 rifles, each with its own advantages and applications:
| Scope Ring Height | Description | Applications |
|---|---|---|
| Low Profile | Minimal height above the receiver | Compact firearms, close-range shooting |
| Medium Profile | Standard height, providing a balance between height and weight | General-purpose firearms, medium-range shooting |
| High Profile | Significant height above the receiver | Long-range shooting, heavy scopes |
Factors to Consider When Choosing Scope Ring Height
Several factors should be considered when selecting the appropriate scope ring height for your AR-15 rifle:

-
Place the scope in the mounting rings and secure it to the rifle.
-
Use a caliper or ruler to measure the distance from the top of the scope to the top of the receiver.
-
Record the measurement and compare it to the desired scope ring height.
