Which scope rings do I need?

Nov 25, 2022
  • First, you’ll need to identify the tube diameter of your scope.

25.4mm(1 inch), 30mm, 34mm and 35mm are the most common tube diameters. If you have a 34mm scope, just choose among 34mm scope rings.

  • Second, identify the best scope ring height for yourself.

         How to properly measure the required scope rings height?

For many shooting beginners, how to properly measure the required rings height always bothers them. So it is important to get the required mount height by the correct measurement method. First, we need to consider three factors:

    1. the outside diameter of the scope’s objective (not the size of the objective lens)
    2. the height of the front of your base/rail from the barrel (As the first picture: the height of blue arrow)
    3. the height of your rings from the top of the rail to center line(As the second picture: 40mm)

The height of the front of your base/rail from the barrel and the half of the outside diameter of the scope together must be greater than the height of your rings from the top of the rail to center line. Confirm that your scope’s objective lens will have enough room to sit on top of the receiver without touching the barreled action, so that it can be used regularly.

  • Third, what types of rails your rifle belong to?

There are mainly 3 types of rails you will encounter: Picatinny rail, Weaver rail and Dovetail rail. Scope rings will mark clearly which rails they can be attached to, so you can choose the proper scope rings according to the type of rails you need.

  • Finally, do you like tactical scope rings more?

If you are more concerned with precision than weight savings, it is better to choose tactical style scope rings.

Therefore, take a simple example. If the tube diameter of your scope is 34mm, the ring height you need is 1 inch, and you prefer tactical style for your Picatinny rail rifle. It’s highly recommended to choose our 34mm Tactical 1” Low Picatinny Mount Rings.
