Breacher C1
The thermal clip-on built to keep your day scope, your zero, and your precision intact.
$1300.00$1199.00
You've spent time building the precision rifle you trust. Tuned the load. Zeroed the glass. Logged the cold-bore drift. The last thing you want to do is throw all that work away to add thermal capability.
The Breacher C1 doesn't ask you to.
It mounts in front of your existing day scope. Your zero stays. Your reticle stays. Your hard-earned precision stays. When you don't need thermal, it removes in seconds.
12µm pixel pitch. 25mK NETD. 60Hz refresh. The largest display in its class — 800×600 OLED. 1,000-meter detection range. 7.8 oz / 220 g without battery — roughly half the weight of typical thermal clip-ons. $1,300.
Add the capability. Keep the rifle. Stand ready.
Why Most Thermal Setups Force a Compromise
The traditional options for adding thermal to a precision rifle have all required compromise.
Option one: swap your day optic for a dedicated thermal weapon sight. You lose your zero, lose your day capability, and turn your precision rifle into a thermal-only rifle.
Option two: mount a thermal as a secondary optic somewhere awkward. Offset rails, ring-mounted optics, makeshift solutions all of them add weight, complicate your zero, and degrade the rifle's handling.
Option three: accept that your precision rifle is a daytime tool and buy a separate thermal rifle. Twice the cost, twice the maintenance, twice the load to carry.
The Breacher C1 is option four: the thermal capability you need, in front of the optic you already trust, with no permanent change to the rifle. Mount it when you need thermal. Remove it when you don't. Your day scope's zero is still your zero every time.
This is how serious operators have run thermal for years. The Breacher C1 makes that configuration accessible.
Premium Thermal Foundation, Class-Leading Display
Most thermal clip-ons in this price range still ship with legacy 17µm pixel pitch, 35-50mK NETD, 30-50Hz refresh, and basic LCD displays. The Breacher C1 is built around premium specs in every category that drives image quality.
12µm pixel pitch. Smaller pixels deliver sharper images, better contrast, and better resolution at the edge of magnification. The kind of pixel pitch you typically only find at the $2,500+ tier.
25mK NETD. Premium-grade thermal sensitivity. The sensor reads thermal differences others miss bedded animals on warm ground, low-contrast targets in mid-summer heat, conditions where lesser thermals wash out.
60Hz refresh. Smooth scanning, smooth tracking, no perceivable lag when you swing the rifle or follow a moving target.
800×600 OLED display. This is where the Breacher C1 separates from everything else in its class. Most competitors at this price ship with low-resolution LCDs. The C1's 800×600 OLED delivers true blacks, high contrast, and image quality that holds up at full magnification — which is what you actually need from a clip-on running in front of a magnified day optic.
1,000-meter detection range. Real working range for predator hunting, perimeter security, and long-range identification.
Up to 4x digital zoom. Refine the picture without losing the wide field of view that makes a clip-on useful.
7.8 oz — Roughly Half the Category Norm
Typical thermal clip-ons in this class run 12-18 oz (340-510 g). Mount one of those in front of an LPVO on a working precision rifle and you've added the equivalent of a loaded 30-round magazine to the front of your rifle. The handling suffers. The fatigue compounds over a long session. The rifle that drove cleanly between targets at the range now feels like a different gun.
The Breacher C1 weighs 7.8 oz / 220 g without battery. That's not just lighter than competitors it's nearly half the weight class.
What that means in practice: your precision rifle still handles like a precision rifle. The point of balance doesn't shift dramatically. A long stalk, a long perimeter scan, or a long match doesn't punish your support arm. The clip-on disappears into the system the way a clip-on should.
This is the weight that makes a thermal clip-on practical for working precision rifles, not just bench tools.
Built for the Rifle You Already Trust
Working precision rifles. Add thermal capability to your sub-MOA build without disturbing the day optic, the zero, or the load you've developed for it. The C1 is the configuration serious precision shooters have always wanted.
Predator and hog hunting at distance. 1,000-meter detection range and the magnified clarity of running thermal through your day optic — instead of on top of a small thermal display — gives you long-range identification capability that compact thermal sights can't match.
Multi-mission carbines. Property defense by day, predator scanning at night, hunting on weekends. One rifle, one zero, one optic — with thermal capability layered on top when you need it and removed when you don't.
Tactical and defensive use. Redundancy matters. The C1 doesn't replace your day optic; it supplements it. If the thermal fails — battery dead, sensor damaged, electronics compromised you still have a fully functional rifle with its original zero. No single point of failure.

Compatible Day Optics
The Breacher C1 is designed to work in front of standard precision day optics:
LPVOs (1-6x, 1-8x, 1-10x)
Fixed-power prism scopes including ACOG and similar designs
Mid-magnification scopes (3-15x, 4-16x) for benched and distance-shooting configurations
Quality red dots and holographic sights for shorter-range applications
Your zero is preserved because the Breacher C1 doesn't change your day optic's relationship to the bore. It sits in front of your day scope and presents a thermal image through your existing optical system. Same reticle, same zero, same shot placement.
For magnified day optics, the thermal image scales naturally with your magnification setting giving you both the wide-field detection capability of thermal and the precision identification capability of magnified glass, in a single sight picture.

Frequently Asked Questions
Will the Breacher C1 work with my existing day scope?
The C1 is designed to mount in front of standard precision day optics LPVOs, prism scopes, mid-magnification scopes, and quality red dots. It works with most popular setups. Compatibility depends on your scope's objective lens diameter and your rail configuration. If you have a specific setup you want to verify, reach out and we'll confirm fit.
Will mounting the C1 affect my day scope's zero?
No. That's the entire point of a thermal clip-on. The C1 sits in front of your day optic and doesn't change the optical relationship between your reticle and your bore. Your zero stays. Your reticle stays. Your shot placement stays.
How long does it take to mount and dismount?
Under a minute, both directions. The C1 uses a quick-attach Picatinny mount designed for repeatable installation. Some users keep it permanently mounted; others run it as removable thermal capability for night sessions. Both workflows work.
How does the 800×600 OLED display compare to LCD displays in other clip-ons?
It's a significant upgrade. OLED delivers true blacks (instead of the gray-on-gray of basic LCDs), much higher contrast, faster pixel response, and better viewing in changing light conditions. Combined with the 800×600 resolution — which is well above the typical 320×240 LCD found in entry and mid-tier thermals — it means you actually see the image quality the sensor delivers, instead of a degraded version.
What's the realistic detection range vs. identification range?
Published detection range is 1,000 meters. Real-world identification range knowing specifically what you're looking at is closer to 250-350 meters depending on conditions, target type, and ambient temperature contrast. Both numbers are excellent for working precision rifles in predator hunting, perimeter security, and tactical use.
Can I run the C1 with a suppressor?
Yes. The C1's mounting position in front of the day optic doesn't conflict with most suppressor configurations. As with any optical setup, we recommend confirming clearance based on your specific suppressor and barrel length.
What's the weight including battery?
Published weight of 7.8 oz / 220 g is without battery. Add approximately [insert battery weight] for the battery in standard configuration. Even with battery, the C1 remains roughly half the weight of typical clip-ons in its class.
How does cold weather affect performance?
Battery runtime is published at 5 hours under standard conditions. Below 32°F, expect noticeable runtime reduction typical of all electronic optics. Image quality and sensor performance remain stable across the operational temperature range. We test runtime at temperature, not at room temperature, so the published number reflects realistic field conditions.
What's the warranty?
The Sentinel Covenant. 100% QC inspection on every unit before it ships, real human support if something does fail, no fine print designed to deny claims. Full warranty details at our warranty page.
