tighting scope rings with torque wrench to secure rifle scope

Image Referenced VORTEX OPTICS

Mounting a scope to a precision rifle looks simple, but it’s not easy!

Here is why…

Doing it wrong on a precision rifle results in missing shots and endless adjustments to fix your zero, and one thing particular is how people torque the screws on the scope rings.

Inexperienced people hand tight scope rings and mounts, but that’s not what the professionals do.

In order to maximize accuracy & resist recoil for a riflescope, setting the proper torque values on scope rings and bases are a must. Getting an affordable torque wrench like the Wheeler FAT wrench is the first step, which helps you to mount optics correctly.


For this reason alone, we have created this list of proper scope ring torque specs reference guide based on brands and models to help you get more accurate.

The Importance Of Proper Torque Value For Scope Rings

By having the proper torque value on the scope rings will hold the scope tight and keeping it from slipping due to recoil.

In addition, the proper torque will ensure the scope tube doesn’t get damaged, and retain zero.

Whether you’re using High or Low Power Variable optics this is very important.

There are two common torque values:

  • Inch-Pound
  • Foot-Pound

Inch-Pound is the unit of measurement used for scope mounting. The Foot-Pound value is used for something a little more heavy duty such as car wheels bolts and structural installations.

High-quality fastener and screws can exert an adequate amount of bolt stress either static or dynamic, in order to hold parts in place.  Most high-quality rifle scope rings are well made, so there is nothing to worry about.


What’s Scope Lapping And Why It’s Important

Lapping Scope rings Mismatch

Scope lapping is a layman’s term is used to describe proper alignment check between the scope rings. Even if you have a super expensive riflescope, you still need to do this part correctly.

It’s the process of taking 2 or more surfaces and applying abrasive compound between them, and create friction between the parts. Most scope rings have a rough interior surface that is uneven and it can scratch the finish on a fine scope upon heavy recoil.

Lapping can also help smoothen the inside of the rings, and create even surface contact when the scope is mounted.

It’s a very important and valid practice to improve the performance of scope mounts.

If you want to invest in a scope lapping toolset that also includes the lapping compound, Wheeler Engineering has one of the best and you can get them here on Amazon.


Vertical Lapping VS. Horizontal Lapping

Vertical Split and Horizontal Split

Images Referenced From Warne 

Horizontal split is common with windage adjustable scope rings because they tend to be off-center from the base, which leads to misalignment due to the loss in surface contact. The lapping help to bring back alignment.

Vertical split generally creates a slim side profile around the scope and it has to flex around the tube slightly to tighten.

For more information please check out this post that Warne has on their site here.


Should Scope Rings Have A Slight Gap ?

Every time when you fit the ring mount together, there will be a slight gap. The gap must stay even from both sides. Overtightening in attempt to close the gap will damage the scope.

What Are the Best Torque Wrench For Scope Mounting?

To start perfecting your rifle setup you need to get torque wrenches that let you adjust the torque setting. For gunsmithing type of work, I highly recommend the Wheeler FAT torque wrench. It’s the best value gun tool to have for getting the job done. Check out how to use a torque wrench for gunsmithing here.


Is Loctite Required On Scope Ring Screws?

Blue Loctite is recommended when securing the scope ring, but it’s not a must. If you purchased a high-quality scope mount then it should come with tight tolerance mounting screws. As long as you torque them correctly, Locktite is not required.

Warning: Do Not Use Red Loctite



How Does Mounting Screw Size Affect Torque Setting Value

A high-quality scope mount always comes with high-quality mounting screws. Remember not to over torque the screws, it may cause ring clamp damage to the scope body.

Torx screws are far more popular because they let you torque it without the bit slipping or damage the screw slot. T-15, T-20 TORX sizes are most common for firearm accessories.

If you need some high quality TORX screws you can get some here on Amazon.

How To Avoid Over Torquing Screws On Scope Rings

Different screws have different screw torque limits. Please make sure your scope is placed on a steady platform while being mounted.

Be patient and go slow, and double check the torque setting value on the screw to prevent any damage to the scope body and scope rings.


Wrap Up On Scope Ring Torque Specs

Mounting scope with the proper torque value is important for a rifle setup. It requires you to pay attention to details and respect the science behind it.

Proper scope mount will ensure your rifle scope maintain zero, and it prevents scope clamp damage. Torque the screws using accurate torque wrench is important to reach maximum performance.

Everyone in the precision shooting community should spend time researching this instead of just hand tight. I hope you find this reference helpful when mounting your scope.
