Adjusting the scope ring height is a crucial step.

But how to determine it?

Let’s find out together!

How to Determine Scope Ring Height

Best Way to Determine Scope Ring Height

A sure-fire method to determine scope ring height. Before ordering scope rings for rifles it’s necessary to determine the correct height. This article shows how to do it.

You shouldn’t buy a scope with rings that are too high or too low.

Why is proper scope ring height important?

Ring heights should be adjusted to ensure a good cheek weld. Too high or too low of a ring could cause problems with your scope hitting the barrel.

How do I measure my scope height?

Most rifle scopes are identified with three numbers: minimum magnification, maximum magnification, and objective lens diameter in millimeters. The objective lens diameter is usually measured in millimeters, but it should be divided by two to get the scope height.

The result is the distance from the middle of the scope body to its outermost edge at its thickest point. A rough estimate of the scope height is obtained by taking the objective lens diameter, adding 4mm for the thickness of the body, and dividing the result by two. An exact measurement is better than a rough estimate.

To convert from inches to millimeter, multiply your measurement by 0.0254.

Ordering Your Scope Rings

When ordering rings, make sure to check the actual size of your rifle before placing an order. Some manufacturers’ rings may be too big or too small for your particular rifle. Make sure you measure the distance from the bottom of the barrel to the top of the scope mount. You should also measure the distance from the top of the mount to the top of the ring.

Rings are measured by the A height. You must add 5″ for a 1″ scope tube. 59055″ for a 30mm scope tubing. 66929″ for a 34mm scope tubing. 688975″ for a 35mm scope tubing.

Scope rings are usually made out of metal or plastic. You can buy them at any gun shop or online store. Some people prefer buying them from a local gun shop because they know what size ring they need. But if you want to save some money, you can always order them online.

Base Height

The base height of a rifle scope is important because it determines how far away objects appear when they are viewed through the scope. A higher base height allows for greater magnification, which means that distant objects appear larger. This makes it easier to hit targets at longer distances.

Scope Tube Diameter

Scope Tube Diameter refers to the size of the tube inside a riflescope. The larger the diameter, the bigger the field of view. A large diameter allows for greater magnification.

Bolt Handle

Bolt Handle in a Rifle Scope is the part that holds the scope onto the rifle. The bolt handle is usually made out of metal or plastic.

Bolt Action Clearance

Bolt Action Clearance is the distance between the front sight and the rear of the barrel when the rifle is at full lock back. This measurement is important because it determines how much the scope has to be adjusted for windage and elevation. The smaller the number, the closer the scope must be set up to the target.

Barrel Clearance

Barrel clearance refers to how far away from the objective lens the shooter must be for the scope to be properly zeroed. The closer the shooter is to the objective lens, the less likely he/she will be able to see the target.

Objective Bell

Objective Bells are used for hunting. They help to keep the scope zeroed in at long distances.

Ocular Bell

Ocular Bells are used to help the shooter aim better at longer distances. They work by reflecting light into the eye, which helps the shooter focus on the target. The best way to use them is when you are shooting at long ranges.

Bolt Clearance

Bolt clearance is the distance between the front end of the barrel and the rear sight. The proper amount of bolt clearance is determined by the length of the rifle’s stock and the scope height. If the scope is too high, then the bolt won’t clear the top of the receiver. If the scope is set too low, then the bolt may hit the bottom of the receiver.

Inch Scope Tube

A scope tube is a part of a rifle scope that holds the reticle and allows for adjustment of magnification. The Inch Scope Tube is designed to be used with both iron sights and telescopic sights.

Scope Ring Sizes

Scope rings are used for adjusting the size of the objective lens inside a rifle scope. The objective lens has a specific diameter which determines how much light can pass through the lens. This affects the magnification power of the scope. Most scopes come with two rings which allow adjustment from 2x to 10x.

Tapered Barrel

Tapered barrels are used in riflescopes to help reduce glare from the sun. The taper helps the scope focus better at different distances.

Riflescope Rings

Riflescopes are used for hunting purposes, especially deer hunting. The scope is mounted on a rifle barrel, which allows the hunter to view the target at longer distances. A riflescope ring is a device that attaches to the end of the riflescope and holds the riflescope steady while aiming.

Dovetail Rings

Dovetail rings are used to connect the scope body to the rifle barrel. They allow for better alignment between the two parts and prevent them from moving during shooting.

Rear Eye Piece

Rear eyepieces are used to help you focus on the target through the scope. The rear eyepiece is usually located at the end of the tube, which allows you to look through the scope while looking downrange. This helps you align your sights with the crosshairs.

Single-piece Mounts

Single Piece Mounts are the mounting hardware used for attaching accessories such as scopes, lasers, lights, etc. to riflescopes. They are also known as “Picatinny” rails. The Picatinny rail system was developed by the U.S. military during World War II.

Objective Lenses

Objective lenses are used in riflescopes to adjust the magnification of the scope. The higher the number, the greater the magnification. Most scopes come with at least one set of 4x, 10x, 20x, 40x, 60x, 100x, 200x, 400x, 600x, 800x, 1000x, 2000x, 3000x, 4000x, 6000x, 8000x, 10000x, 12000x, 15000x, 20000x, 25000x, 300000x, 350000x, 4000000x, and 500000x.

Type of Rings

Proper rings

The proper ring for a rifle scope is the one that matches the size of the target object. If you use a 1x magnification, then a 100mm ring should be used. If you use a 2x magnification, then a 200mm ring should be used, etc.

Medium rings

A medium ring is a distance from the center of the reticle to the edge of the crosshairs. The closer the reticle is to the target, the smaller the ring.

Wrapping it up…

The most important thing when determining the correct scope ring height is to get one that fits your rifle perfectly. The next step is to install the scope ring properly.

Once installed, you’ll notice that the scope ring height will change slightly as the scope moves in relation to the barrel.

It’s important to remember that this is normal and it’s caused by the way the scope is mounted.
