Quick Answer
To determine the right height for scope rings, measure the height of the rifle's scope base and add 1/4 to 1/2 inch to ensure proper clearance between the scope and the barrel. Consider the type of rifle and scope you're using to make this calculation. Check the manufacturer's recommendations for specific height requirements.
Measuring the Scope Base
To determine the right height for your scope rings, you’ll need to measure the height of the rifle’s scope base. You can do this by placing the rifle on a flat surface and using a ruler or caliper to measure from the surface to the top of the scope base. Record this measurement in inches. For most rifles, you’ll want to add 1/4 to 1/2 inch to this measurement to ensure proper clearance between the scope and the barrel.
Calculating the Ring Height
When calculating the ring height, consider the type of rifle and scope you’re using. For example, if you’re using a high-powered scope with a long eye relief, you’ll want to add more clearance to ensure the scope doesn’t interfere with the barrel. A good rule of thumb is to add 1/4 inch for every 10x magnification power above 4x. If you’re using a rifle with a short action or a scope with a short eye relief, you may be able to get away with a lower ring height.
Choosing the Right Rings
When selecting scope rings, look for ones that are specifically designed for your rifle and scope. Make sure the rings are compatible with your scope base and that they have the correct height and width for your needs. Some scope rings come with adjustable height, which can be useful if you’re not sure what height you need. However, if you’re looking for a more precise fit, consider using fixed-height rings.
