The installation of clip-ons

The installation of clip-ons for thermal and night vision riflescopes (external objective diameter chart)

Intro

The usage of infrared thermography and night vision from hunters is expanding. The majority of wild creatures stay concealed from view in the woods throughout the day. They emerge either at sunrise or at dusk to feed in the fields. A regular daytime riflescope is not very useful in this situation. Looking at something from a contrasting perspective, a thermal or night vision equipment gives the hunter access to a completely new realm. These tools have shown to be effective in helping to stop the increase of African swine fever cases. As the terrible illness upswings, it is essential to control the wild boar numbers to the point where the likelihood of it escalating is significantly decreased.

Producers make any of the following monocular, binocular, riflescope, and riflescope clip-on. Only in a few countries in the world it is illegal to operate thermal and night vision devices for hunting. That is why, the producers provide clip-ons, the usage of which is generally more accepted and authorized in the majority of locations. The clip-ons are the most versatile type as well since they are frequently employed as a monocular. Verify if using a thermal or night vision equipment for hunting is permitted in your country or hunting area before making a purchase.

Before purchasing an adapter to connect a night vision or thermal clip-on with a riflescope, there are a number of significant considerations that should be made.

The first requirement is that the weapon musn’t have a parallax adjustment ring on the objective since the mounting space is not sufficient for a clip-on adapter on such weapons.

Second, since the field of vision is very small once the gadgets are linked, the riflescope’s minimum magnification level should not surpass 8 times.

Additionally, it is challenging to perceive the full instructions on the clip-on display.

It’s crucial to understand the riflescope’s external objective diameter, not the objective lens diameter, in order to place a clip-on on it. The objective lens diameter alone is inefficacious to determine the external objective diameter. For instance, the external objective diameter of a weapon could range between 56 and 60 mm if the objective lens’s diameter is 50 mm. Similar considerations apply to riflescopes with 56 mm-diameter objective lenses; the external objective diameter might range between 62 and 66 mm, etc. Be careful to get the correct adapter because they are produced for both thermal and night vision clip-ons by numerous distributors.

Outer objective diameter comparison

Although each of these riflescopes has a 56mm objective lens, their external objective diameters vary. The external objective diameter of the Zeiss Conquest V6 2.5-15×56 is 62 mm (left), the objective diameter of the Athlon Helos 8-34×56 is 63.5 mm (center), and the objective diameter of the Vortex Razor HD GEN II 4.5-27×56 is 65 mm (right).

The words “objective lens diameter” and “external objective diameter” are still misused by our clients. We want to clear up any misconceptions with this article. Customers may save time and prevent possible measuring errors by finding their riflescope and the associated external objective diameter in the list rather than needing to use the measuring equipment.

Adapter numbers

There is a number beside each adapter’s name. The FN cover ring adapter marked “56” is appropriate for riflescopes having an external objective diameter of around 60–65 mm, making Pulsar the unique adapter manufacturer whose number matches to the diameter of the riflescope’s objective lens. For instance, a Smartclip adapter marked “56” may be used with weapons that have an external objective diameter of 56 mm. All other adapter manufacturers offer numbers that correlate to the outside objective diameter of the rifle.

Due to the widespread adoption of certain external objective diameter values by riflescope producers, they are sometimes referenced as standards. The following are the most popular diameters:

48 mm
56 mm
62 mm

Chart of the external objective dimensions of riflescopes

The producers of riflescopes are listed alphabetically hereunder. The riflescope series are given under each brand division, followed by models with appropriate objective diameters. Please be aware that not all producers are included in this list. When we discover any models that are excluded from this table, we will update it. We welcome information from you our readers, on the external objective diameters of riflescopes lacking in the provided chart. Additionally, we respectfully request that you inform us if you find any errors or have any queries about the subject. We are thankful in advance.

Closing

To summarize, here is how to implement this manual:

1.Make sure your riflescope does have an adjustable objective ring since if you don’t, you won’t be able to attach the adapter.
2.To get the most out of the clip-on, please remember that your riflescope’s magnification shouldn’t be higher than 8x!
3.To determine the diameter of your riflescope’s objective, locate it on the table. Conversely, you can use a measuring device to determine the external objective diameter. Buy the right adapter.
4.Recall that some producers, like Pulsar, specify the objective lens’s diameter rather than the external objective’s diameter in the adapter’s name. However, the external objective diameter is more commonly used since it is less misleading.
