Thermal Clip-On Scopes — Convert Your Day Optic to a Night-Hunting Rig
Thermal clip-on scopes let you turn your existing daytime riflescope into a powerful night-hunting setup without changing your zero. These devices mount in front of your glass and give you a thermal image through your regular reticle, so your cheek weld, eye relief, and holds all stay the same.
At Thermal Bros, we focus on clip-ons that actually hold point of impact, offer clear images, and integrate well with common hunting scopes. If it’s here, we’d trust it in front of our own optics.
Why Run a Thermal Clip-On?
-
Keep your favorite daytime scope and reticle — no need to swap optics.
- No re-zeroing every time you change from day to night.
-
Use one thermal on multiple rifles with the right adapters.
-
Familiar handling and balance with your existing rig.
Best Uses for Clip-On Thermals
- Hog and predator hunting when you already love your daytime scope
- Long-range setups where your current optic is dialed in
- Hunters who rotate one thermal between multiple rifles
- Ranch and property protection with a dual-use rifle
How to Choose the Right Clip-On
-
Compatibility with your day scope: Clip-ons usually work best with lower to mid-power variables (1–6x, 2–10x, 3–15x). Too much magnification kills image quality.
-
Resolution: 384 cores are solid for many hunters. 640 shines if you hunt open country or want the cleanest image through magnification.
-
Mounting & adapters: Make sure the clip-on and mounting system are solid and repeatable on your rifle.
-
Battery life: If you plan on all-night hunts, prioritise good runtime and easy recharging/swapping.
FAQ: Clip-On Thermals
Q: Will a clip-on change my zero?
A: A good clip-on, mounted correctly, should maintain your daytime zero. That’s the entire point — day rig by day, thermal killer by night.
Q: Can I move one clip-on between rifles?
A: Yes, with the right mounts and adapters. Just make sure each rifle is checked and confirmed before serious hunting.
Q: Is a dedicated thermal scope better?
A: Dedicated thermals usually offer more features and flexibility, but clip-ons win when you want to keep your daytime glass and reticle.
