Top 6 Best Thermal Scope For 17 Wsm in 2026

The .17 WSM is a fast, flat-shooting rimfire round, and I like it most for small predators, varmints, and pest-control work where clean identification matters more than raw recoil management. Because the cartridge is light-recoiling and often used at practical nighttime distances, I do not look for the same thermal scope setup that I would mount on a heavy centerfire rifle. For a .17 WSM, I want a thermal scope that is clear, lightweight enough to keep the rifle handy, simple to zero, and not so overbuilt that it ruins the balance of the gun.

I have spent time behind several styles of thermal optics, from compact entry-level scopes to high-end 640-class units, and for a .17 WSM rifle I usually favor a moderate magnification range, dependable detection, and a mounting system that does not require me to fight the rifle every time I head out. Below are my top six picks for the best thermal scope for 17 WSM in 2026, each ranked for a specific purpose.

Short Quick Summary

My favorite overall choice is the Pulsar Thermion 2 XG50 Thermal Riflescope because it feels like a strong match for a precision-minded .17 WSM setup. For tighter budgets and closer-range rimfire hunting, the Sightmark Wraith Mini 2-16×35 Thermal Riflescope makes sense. If I wanted a compact, practical thermal for a walking varmint rifle, I would look closely at the AGM Rattler TS35-384 Thermal Imaging RifleScope 384×288. For shooters who want built-in ranging help, the ATN Thor 5 LRF 2-16x 640×480 Smart HD Thermal Rifle Scope is very appealing. The Burris Optics BTS35 V2 Thermal Imaging RifleScope is a solid rugged pick, while the DNT Optics Hydra 256×192 19mm Multi-Function Thermal Scope fits shooters who want a compact multi-function option.

Top 6 Best Thermal Scope For 17 Wsm in 2026

Pulsar Thermion 2 XG50 Thermal Riflescope

The Pulsar Thermion 2 XG50 is my top overall pick for a .17 WSM because it gives the rifle a more traditional scope feel while still delivering the kind of thermal performance I want for nighttime varmint hunting. I like this style on a rimfire because it does not feel awkward on the gun, and the sight picture makes careful shot placement easier.

Product Specs

• Thermal riflescope design
• XG50 model configuration
• Traditional scope-style body
• Suitable for predator, varmint, and night hunting setups
• Works well for precision-focused .17 WSM rifles

Pros

• Excellent fit for a serious rimfire varmint rifle
• Traditional scope shape feels familiar
• Strong choice for identification and careful aiming
• Good for hunters who want a premium setup

Cons

• More scope than some casual .17 WSM shooters need
• Higher-end choice compared with basic thermal options
• May feel unnecessary for very close-range pest control

When I use a .17 WSM, I want confidence before I press the trigger, especially on small targets. This is where the Thermion-style layout stands out to me. It gives me a steady, rifle-scope-like feel instead of making the rifle feel like it has a boxy gadget mounted on top.

Online customers often focus on clarity, usability, and how natural the Thermion-style body feels compared with bulkier thermal optics. For a .17 WSM shooter who wants a clean and polished setup, I think this is the most complete choice here.

For mounting, this scope uses a traditional riflescope-style mounting approach, so I would pair it with compatible rings suited to the rifle and rail height. On a .17 WSM, I prefer keeping the mount as low and stable as the rifle allows.

ATN Thor 5 LRF 2-16x 640×480 Smart HD Thermal Rifle Scope

The ATN Thor 5 LRF 2-16x is the scope I would choose if I wanted a feature-rich thermal for a .17 WSM. The built-in LRF idea is useful because the .17 WSM is flat-shooting, but distance still matters on small targets. I like having ranging help when I am dealing with rabbits, raccoons, foxes, or other small animals at night.

Product Specs

• 2-16x magnification range
• 640×480 thermal class
• Built-in LRF configuration
• Smart HD thermal scope design

Cons

• More settings to learn
• Heavier and more complex than simpler scopes
• Not my first choice for a minimalist rifle

My experience with smart thermal scopes has taught me that features are only helpful when they do not slow me down. On a .17 WSM, I like the 2-16x range because I can stay low for scanning and still have enough magnification for a careful shot. The LRF feature is especially valuable when judging distance in open fields.

Customers often comment on ATN-style scopes for their technology, recording features, and useful hunting tools. I see this as a good match for a shooter who enjoys settings, data, and a more modern optic experience.

For mounting, this is a dedicated riflescope and typically mounts to a rifle rail with compatible scope hardware. I would make sure the rail is solid and use a mount height that gives a natural cheek weld.

Online buyers often appreciate the AGM Rattler line for being compact, usable, and practical for nighttime hunting. I think the TS35-384 version hits a sweet spot for rimfire shooters who want useful detection without turning their rifle into a heavy rig.

For mounting, this is a direct rifle-mounted thermal scope. I would mount it on a stable rail and check eye relief, rifle balance, and zero carefully before hunting.

Burris Optics BTS35 V2 Thermal Imaging RifleScope

The Burris Optics BTS35 V2 is my pick for hunters who want a tough, straightforward thermal scope from a familiar optics name. On a .17 WSM, I like this type of optic for field use where durability and simple operation matter more than chasing every advanced feature.

Product Specs

• Thermal imaging scope design
• Hunting-focused configuration
• Suitable for nighttime varmint and predator use
• Practical size for rifle mounting

My field preference is simple: I want gear that turns on, holds zero, and lets me identify what I am aiming at. The BTS35 V2 fits that kind of mindset. For a .17 WSM, I would use it on a rifle dedicated to night pest control or predator calling, especially where shots are moderate and repeatable.

Online customers often look at Burris products with durability and brand trust in mind. I think this scope makes sense for a shooter who wants a thermal that feels like hunting equipment rather than a complicated electronic toy.

For mounting, the BTS35 V2 is a rifle-mounted optic and should be installed on a compatible rail with the proper mounting hardware. I would verify clearance, torque, and zero stability before using it in the field.

Sightmark Wraith Mini 2-16×35 Thermal Riflescope

The Sightmark Wraith Mini 2-16×35 is my best value pick for a .17 WSM. I like it for shooters who want to get into thermal hunting without building the most expensive rimfire setup possible. The 2-16x magnification range also makes sense for the cartridge.

Product Specs

• 2-16x magnification range
• 35mm objective class
• Mini thermal riflescope design
• Compact hunting optic
• Good fit for close to moderate rimfire distances

Pros

• Good entry point for thermal hunting
• Compact size suits .17 WSM rifles
• Useful magnification range
• Practical for small-game and pest-control work

Cons

• Not as premium as high-end thermal scopes
• Image detail may not match more expensive units
• Better for realistic rimfire distances than extreme range

I like compact scopes on .17 WSM rifles because they keep the rifle lively. The Wraith Mini feels like a smart option for someone who wants thermal capability for nighttime pests but does not want the optic to cost more than the entire rifle setup several times over.

Customer comments around Wraith-style optics often mention value, ease of use, and suitability for nighttime hunting. I would choose this for a farm rifle, a first thermal scope, or a practical rimfire rig that sees regular use.

For mounting, it is designed as a riflescope, so I would mount it directly to a compatible rail using the correct mount setup. I would avoid overly tall mounts unless the rifle stock requires extra height.

DNT Optics Hydra 256×192 19mm Multi-Function Thermal Scope

The DNT Optics Hydra 256×192 19mm Multi-Function Thermal Scope is my lightweight multi-function pick. I would not put it above the premium 640-class optics for detail, but for a .17 WSM used at closer ranges, I can see the appeal. It is compact, practical, and purpose-built for shooters who want a flexible thermal option.

Product Specs

• 256×192 thermal class
• 19mm configuration
• Multi-function thermal scope design
• Compact profile
• Suitable for close to moderate varmint use

Pros

• Compact and handy
• Good for lightweight .17 WSM builds
• Multi-function design adds flexibility
• Sensible for close-range pest control

Cons

• Lower thermal resolution than 384 or 640-class scopes
• Not my choice for longer-distance identification
• Best used within realistic rimfire hunting ranges

When I think of a .17 WSM truck gun or compact night hunting rifle, the Hydra makes sense. I would use it where targets are expected at moderate distances and where rifle handling matters. It is not the optic I would choose for maximum detail, but it can be a useful tool when size and simplicity matter.

Online customers usually compare compact thermals based on convenience, price, and whether the image is good enough for their normal distances. For a .17 WSM, that “good enough at practical range” idea is important because this cartridge is not a long-range centerfire predator round.

For mounting, this thermal scope should be mounted directly to a compatible rifle rail using the proper included or compatible mount. I would test it carefully after zeroing because compact multi-function optics still need a stable mounting setup.

How to Choose the Right Red Dot Sight

Even though this article is about thermal scopes, the same practical mindset I use for choosing a red dot sight also applies here: match the optic to the rifle, the target, and the distance. For a .17 WSM, I do not automatically choose the biggest or most expensive thermal. I choose the one that helps me identify small targets clearly and keep the rifle comfortable.

First, I look at resolution. A 640-class thermal gives more detail, which helps when I need better identification. A 384-class scope can be a strong middle ground. A 256-class scope can still work for closer pest-control distances, but I keep my expectations realistic.

Second, I consider magnification. The .17 WSM does not need extreme magnification for most nighttime work. I prefer a low base magnification with enough top-end zoom for precise aiming.

Third, I pay attention to weight and balance. A lightweight rimfire can feel awkward if the optic is too large. Compact scopes like the AGM Rattler or Sightmark Wraith Mini can make the rifle easier to carry.

Fourth, I think about mounting. A good thermal scope is only as dependable as its mount. I want a solid rail, proper torque, and a repeatable zero. For a .17 WSM, recoil is light, but sloppy mounting can still ruin accuracy.

Finally, I choose based on real hunting distance. For close pest control, I can use a smaller, simpler optic. For open fields and more demanding identification, I would spend more for a clearer thermal image.

FAQs

What magnification is best for a thermal scope on a .17 WSM?

For my use, a low-end magnification around 2x is very useful, with enough zoom to reach 8x, 12x, or 16x when needed. Too much magnification can narrow the field of view and make scanning harder.

Is a 640 thermal scope worth it for .17 WSM?

Yes, if you want better image detail and target identification. I think a 640-class scope is especially useful in open fields, but casual pest-control shooters may be happy with a 384-class option.

Can I use a heavy thermal scope on a .17 WSM rifle?

You can, but I usually avoid making a light rimfire feel top-heavy. Balance matters, especially if I am walking or shooting from field positions.

Is the .17 WSM good for night hunting with thermal?

Yes, the .17 WSM can be a very effective nighttime varmint cartridge when paired with a good thermal scope. I like it for small predators and pests where low recoil and flat shooting are useful.

Do I need a laser rangefinder for .17 WSM?

You do not need one, but it helps. On small targets at night, distance can be hard to judge, and a scope like the ATN Thor 5 LRF can make shot decisions easier.

Conclusion

For the best thermal scope for 17 WSM in 2026, my top pick is the Pulsar Thermion 2 XG50 Thermal Riflescope because it gives me the clearest premium-style setup for a precision rimfire varmint rifle. If I wanted ranging built in, I would choose the ATN Thor 5 LRF 2-16x 640×480 Smart HD Thermal Rifle Scope. For a compact and practical hunting rifle, the AGM Rattler TS35-384 Thermal Imaging RifleScope 384×288 is hard to ignore.

The .17 WSM does not need an oversized thermal scope to perform well. It needs an optic that balances clean identification, usable magnification, dependable mounting, and rifle handling. Pick the scope that matches your real hunting distance, and your .17 WSM can become a very capable nighttime varmint setup.
