Best Sight Height for Hunting with an AR-15 Platform?

Sight Height Considerations

When determining the optimal sight height for your AR-15, it’s essential to consider the rifle’s barrel length and the type of ammunition being used. A general rule of thumb is to set the sight height to 1/3 to 1/2 of the barrel’s length above the boreline. For a typical 20-inch barrel, this would translate to a sight height of around 6-10 inches. However, this can be adjusted based on the specific rifle and ammunition combination.

Calculating Sight Height

To accurately calculate the sight height for your rifle, you can use the following formula: (Barrel Length x 1/3) + 1 inch. This will give you a starting point for setting your sight height. For example, using this formula on a 20-inch barrel would result in a sight height of approximately 7 inches. However, it’s crucial to remember that this is just a starting point, and adjustments may be necessary based on the specific rifle and ammunition combination.

Practical Application

In practice, it’s often more effective to set the sight height to a specific number based on the rifle and ammunition combination, rather than trying to calculate it. For example, a common sight height for AR-15 rifles shooting 5.56mm ammunition is around 1.5 to 2.5 inches above the boreline. This allows for a clear and accurate view of the target while accounting for the bullet’s trajectory. By setting the sight height to this number, you can ensure that your shots are accurate and reliable, even at longer ranges.
