A riflescope’s tube diameter is an important measurement to know when you’re shopping for a new scope or trying to replace a damaged one. The tube diameter is the size of the inner tube of the scope, and it’s measured in inches. The tube diameter is important because it determines the size of the objective lens, the eyepiece, and the other internal components of the scope.
Tools and Materials Needed
To measure the diameter of a riflescope tube, you will need the following tools and materials:
- A tape measure
- A caliper
- A riflescope
Steps to Measure Scope Tube Diameter
1. Locate the tube diameter markings. Most riflescopes will have the tube diameter marked on the barrel or the objective lens. If your scope does not have the tube diameter marked, you can measure it yourself using a tape measure or a caliper.
2. Measure the outside diameter of the tube. To do this, wrap a tape measure around the outside of the tube and take a reading.
3. Subtract the thickness of the scope rings from the outside diameter measurement. The thickness of the scope rings will vary depending on the type of rings you are using.
4. The resulting measurement is the inside diameter of the tube. This is the measurement you will need to use when shopping for a new scope or replacement parts.
Measuring the diameter of a riflescope tube is a simple process that can be completed with a few tools and materials. By following the steps in this guide, you can easily determine the tube diameter of your scope and find the right replacement parts or a new scope.
Here are some additional tips for measuring the diameter of a riflescope tube:
- Make sure the scope is not mounted to the rifle when you measure it.
- If the scope is dirty, clean it before measuring it.
- Be careful not to damage the scope when you are measuring it.
By following these tips, you can ensure that you get an accurate measurement of the scope tube diameter.
How To Measure Scope Tube Diameter?
Step 1: Gather Your Supplies
To measure the diameter of a scope tube, you will need the following supplies:
- A tape measure
- A pencil
- A piece of paper
Step 2: Align the Tape Measure with the Center of the Scope Tube
Once you have gathered your supplies, you can begin measuring the diameter of the scope tube. First, align the end of the tape measure with the center of the scope tube. You can do this by looking through the scope and aligning the tape measure with the crosshairs.
Step 3: Extend the Tape Measure to the End of the Scope Tube
Once the tape measure is aligned with the center of the scope tube, extend it to the end of the scope tube. Make sure that the tape measure is flat against the scope tube and that it is not touching any other parts of the scope.
Step 4: Read the Measurement
Once the tape measure is extended to the end of the scope tube, you can read the measurement. The measurement will be in millimeters (mm).
Example:
In the example below, the diameter of the scope tube is 30mm.

Measuring the diameter of a scope tube is a simple process that can be completed with a few common household items. By following the steps in this guide, you can easily determine the diameter of your scope tube and purchase the correct replacement parts.
How do I measure the diameter of a scope tube?
There are a few different ways to measure the diameter of a scope tube. The easiest way is to use a micrometer, which is a precision measuring tool that can measure the diameter of a small object. To use a micrometer, first attach the anvil to the scope tube. Then, turn the thimble until the spindle makes contact with the scope tube. The reading on the micrometer will be the diameter of the scope tube.
Another way to measure the diameter of a scope tube is to use a ruler. To do this, first place the ruler flat against the scope tube. Then, use a pencil to mark the point where the ruler meets the inside of the scope tube. Finally, measure the distance between the two marks with a ruler.
Finally, you can also use a string to measure the diameter of a scope tube. To do this, first tie a knot in one end of the string. Then, wrap the string around the scope tube until it comes back to the knot. Finally, measure the length of the string with a ruler.
What is the difference between the outside diameter and the inside diameter of a scope tube?
The outside diameter of a scope tube is the measurement of the tube from the outside edge to the inside edge. The inside diameter of a scope tube is the measurement of the tube from the inside edge to the inside edge. The difference between the outside diameter and the inside diameter is the wall thickness of the scope tube.
What is the standard scope tube diameter?
The standard scope tube diameter is 1 inch. However, there are also scope tubes available in other diameters, such as 30mm and 34mm. The size of the scope tube that you need will depend on the type of rifle that you are using and the type of scope that you want to mount.
How do I know what size scope tube I need?
The size of the scope tube that you need will depend on the type of rifle that you are using and the type of scope that you want to mount. If you are not sure what size scope tube you need, you can consult with a firearms expert or a sporting goods store.
What are the benefits of using a larger scope tube?
There are a few benefits to using a larger scope tube. First, a larger scope tube will provide a wider field of view. This can be helpful for hunting or target shooting in situations where you need to be able to see a wide area. Second, a larger scope tube will allow you to use a higher magnification. This can be helpful for hunting or target shooting at long distances.
What are the drawbacks of using a larger scope tube?
There are a few drawbacks to using a larger scope tube. First, a larger scope tube will be heavier and more expensive than a smaller scope tube. Second, a larger scope tube will be more difficult to mount on a rifle. Finally, a larger scope tube will have more glare and distortion than a smaller scope tube.
How do I clean a scope tube?
To clean a scope tube, you will need a few supplies:
- A cleaning brush
- A cleaning solvent
- A dry cloth
First, remove the scope from the rifle. Then, use the cleaning brush to remove any dirt or debris from the inside of the scope tube. Be careful not to scratch the lens. Next, apply a small amount of cleaning solvent to the dry cloth. Then, use the cloth to wipe the inside of the scope tube. Finally, dry the scope tube with a clean cloth.
How do I protect a scope tube from damage?
There are a few things you can do to protect a scope tube from damage:
- Use a scope cover when the scope is not in use.
- Avoid dropping the scope.
- Do not use the scope in extreme weather conditions.
- If the scope gets wet, dry it off immediately.
there are a few different ways to measure the diameter of a scope tube. The best method for you will depend on the tools you have available and the accuracy you need.
- If you have a micrometer, you can use it to measure the outside diameter of the scope tube.
- If you don’t have a micrometer, you can use a ruler to measure the inside diameter of the scope tube.
- You can also use a piece of string to measure the circumference of the scope tube and then divide that measurement by to find the diameter.
Once you know the diameter of your scope tube, you can use that information to choose the right scope rings or mounts. Be sure to check the manufacturer’s specifications to make sure that the rings or mounts you choose are compatible with your scope tube.
Measuring the diameter of your scope tube is a simple task that can be completed with a few different tools. By following the steps in this article, you can easily find the diameter of your scope tube and choose the right rings or mounts for your rifle.
