What Are Clip-on Optics?

Clip-on optics are sighting tools attached in front of the rifle scope mounted on a thermal rifle explicitly built to co-sight. It is usually accomplished by placing it on an extended Picatinny rail or a fore-end bracket with a Picatinny rail. However, some clip-on optics can be attached directly to the rifle scope.

The best thermal clip-on systems are designed to be mounted in front and in-line with the daytime scope. It has thermal imaging capability that allows for long-wave infrared observation and target identification under adverse conditions, including smoke, light snow, light rain, and low light to total darkness.

Clip-on scope mounts in seconds and requires no re-zeroing. It uses the same daytime rifle scope reticle and doesn’t change the rifle’s shooters. It also uses a high-resolution sensor that provides incredibly crisp detail and shading for rich images and aids for easier target identification of a regular rifle.

What Are The Benefits?

Benefits

 

  • Flexibility and Convenience – It gives shooters flexibility and convenience because, often, a thermal riflescope is only an optional attachment. In other words, shooters can still use their normal day and night rifle scope with or without high-resolution thermal optic attachments like the 3 best clip-on scopes mentioned above.
  •  Versatility – A high-resolution clip-on thermal scope gives versatility because it can be utilized for hand-held use when detached from any weapon or rifle. It can also be mounted on just about any gun that can accommodate a scope, even on crossbows like the Pulser Core FXQ38.
  • Detects the exact location of a target – A thermal riflescope can also detect the exact location of the target because it can also sense residual heat. Thermal hunting scopes can pick up traces of heat signatures, which helps determine if a track of a recently shot animal is still fresh.
  • Ideal for Daytime and Nighttime Use – Thermal scopes can be used for daytime and nighttime use. These scopes also have a more significant advantage than a regular night vision scope because it can work for a dark and bright environment since it uses temperature instead of ambient light.
  • No zeroing required – Thermal scopes do not require shooters to zero. Therefore, shooters don’t need to go through the hassle of swapping optics and possibly lose their zero in the process.

Buying Guide

key factors

Battery Life

Generally, the best clip-on thermal scopes provide at least 4-5 hours of battery life using a pair of CR123 batteries. However, if you want more battery life, it would be best to consider getting the best clip-on thermal scope with an external battery pack.

You may also check if the manufacturer sells a compatible battery pack separately. We also recommend looking for a scope that comes with a rechargeable battery, which may be expensive but will have a more long-lasting battery life.

Durability

It is best to consider looking for a thermal scope made from an aluminum body because it is more lightweight than steel but is as sturdy. We recommend buying a waterproof clip-on thermal scope because it ensures continuous hunting through rain and snow even without worrying if the scope accidentally falls in the water.

Magnification

It is imperative to have a bright and crisp display when hunting and tracking animals, especially during nighttime. It would be best to consider the clip-on thermal scope magnification range because it enlarges the image size several times when zooming in on a target. Some scopes feature higher magnification ranges up to 16x or more and use digital zoom.

However, some models do not feature this functionality. We recommend models with optical magnifications because they use lens adjustments to zoom in on images and targets. Hence they project images clearer even at a maximum magnification level.

Extra Features

To get your money’s worth, you must consider buying the best thermal scope with extra features like the Pulser Core FXQ38. Thermal scopes are naturally expensive, so it is reasonable to choose models that offer additional performance and convenience.

Features such as Wi-Fi connectivity for streaming purposes, GPS location, and digital compasses are the best examples. Some models also come with ballistic calculators, recoil activated video recording, and laser rangefinders.

Refresh Rate

The refresh rate is an important feature that every shooter must consider when buying a clip-on thermal scope. If the refresh rate is high, it may also mean that it would cost more but will come with higher quality, too.

We recommend getting models that feature a refresh rate of 30 – 60 Hz because it makes the image refresh faster and will project a better and more precise image. However, it would be best to consider that models with a 30 – 60 Hz refresh rate would drain the scope’s battery faster.

Mounting System

mounting

It would be best if you also found thermal scopes that are versatile enough to be mounted on different system rails.

Since these clip-on thermal scopes are attachments in front of a day and night scope, binoculars, and other sighting devices, they must be compatible with the firearms you intend them to use.

Color modes

Thermal scopes also have color modes that vary from one model to another. These colors are constituent colors of the images combined to end up with the final image, so deciding which color mode your thermal scope must-have is essential. Some scopes may have RGB scale, grayscale, or CMYK scale. Some models even have up to nine modes that shooters can change based on different conditions.

Reticle Patterns

Reticle patterns are essential to be considered, too, because they have the intersecting lines engraved on the thermal scope’s eyepiece. You would want to get a model with the best reticle patterns, so you will also have the best shooting capability. Reticles also help shooters stay in a position to provide accurate shooting even from a longer distance.

Thermal Imaging

Thermal imaging data is collected at the speed of light in real-time from a wide variety of platforms, including land, water, and air-based vehicles. It is superior to visible imaging technologies because thermal radiation can penetrate smokes, aerosols, dust, and mists more effectively than visible radiation so that animals can be detected over a wide range of normally troublesome atmospheric conditions. [1

The recommended minimum display resolution for clip-on thermal scopes is 384×288. With this resolution, the image quality is ensured to come out pretty good, and you can detect animals as far as 500 yards. On the other hand, a 640 x 480 clip-on thermal scope will let you see as far as 1,000 yards, and image quality is excellent for more money.

Weight & Size

Clip-on thermal scopes are attachments on added sighting devices mounted on a thermal rifle. So, getting a heavy and bulky thermal scope isn’t an ideal option. It would be best to find a compact and lightweight clip-on. Why? Because it is not just good for portability, but it also ensures a more stable balance and better accuracy. So, our best advice would be to get a lightweight clip-on scope, especially when your day scopes are already on the heavier side.

Lens Size

Lens sizes are also important factors to be considered when buying a clip-on thermal scope. Some scopes feature different objective lens sizes ranging from 20mm up to 100mm. However, we highly recommend getting a clip-on with a minimum of 50mm objective lens because it is great for close and mid-range hunting. However, if you want to go for long-range shots, we suggest getting at least a 75mm or 100mm lens.

Scope Detection Range

Thermal scope attachment models come with different detection ranges from close to mid- to long-range shots. However, most standard options offer short detection ranges. Therefore, you need to buy a thermal clip-on that ensures that your rifle’s effective range significantly surpasses the range. Fortunately, with the never-ending improvement of technology, shooters can now find models with very long ranges.

Versatility

A thermal scope is useless, no matter how excellent its features are, if it isn’t compatible with your day scope device. Therefore, you need to ensure that your clip-on scope is compatible with your day scope.

You need to understand that size is not an issue, as most clip-on scopes are designed to go with a wide range of day scope lens sizes. The most important thing to consider checking clip-on scopes is their magnification, as it needs to be compatible with the magnification of your day scope, too.

versatility

Warranty

Of course, you also need to consider the warranty for the best clip-on thermal scope. Some models offer different warranty lengths. Some have a limited offer lifetime warranty that can last up to three to five years. If you are lucky, you can also find manufacturers that offer ten years of warranty, or if you hit the jackpot, you’ll find scopes that offer a warranty that can last longer.

Pricing

If you are considering getting one of the best clip-on thermal scopes, you probably have some money to burn. However, the next question would be, how much are you willing to spend in getting a high-end thermal scope? Remember that even the cheapest thermal scope costs at least $1000.

The good news is, you’ll probably get your money’s worth because most scopes offer excellent features that a regular day scope couldn’t provide. Just think of it as an investment, and then you’re good to go.
