When a piece of gear like the FMP 13 thermal scope appears – costing around $700 and small enough to barely notice – it naturally gets people curious. Is this the point where thermal imaging truly becomes accessible for users accustomed to traditional gun sights, or are there too many trade-offs for such a compact, budget-friendly device? That's exactly what we're looking into by examining the detailed video review from "Arms For Thoughts." This post will lay out his findings on the FMP 13, covering what works, what doesn't, and ultimately, what you should consider if you're thinking about this micro optic.
FMP 13 Technical Specifications: Arms For Thoughts' Detailed Breakdown
To better understand the FMP 13, it's helpful to look at the specific details Arms For Thoughts gave in his review. These technical details give us a better idea of what this small, budget thermal scope is like, especially regarding its size and affordability.
Pistol Sights Fast Mini FMP13
Tiny Footprint, Minimal Weight
The first thing that Arms For Thoughts noted is how small the FMP 13 is. He said it's maybe the smallest thermal pistol sight on the market. Along with this compact size, it weighs in at less than four ounces. This means it adds virtually no bulk or noticeable weight when mounted on a rifle, quite a difference from some of the bulkier, older thermal optics and much larger gun sights.
Key Operational Details
Beyond its physical size, the FMP 13 has several core features that define how it works:
- Sensor Resolution: It uses a 256x192 thermal sensor, which directly affects the clarity and detail of the thermal image.
- Connectivity: There's a Type-C port, but the review specified this is only for external power or software updates, not for charging the battery itself.
- Durability: The scope has an IP67 rating, meaning it’s well-protected against dust and water. It’s also built to operate across a range of temperatures.
- Price Point: All this comes in at around $700, an affordable price that makes it a very competitive option in the thermal market.
This set of features shows the FMP 13 is designed to be an accessible and highly portable thermal solution.
Arms For Thoughts on FMP 13 Strengths and Positive Features
In his review, Arms For Thoughts didn't just run down a list of specifications. He offered real-world observations on what makes the FMP 13 a genuinely appealing thermal scope, especially when you consider its price. During his testing, several key aspects clearly made a positive impression.
Accessible $700 Price Point
One of the biggest draws, which Arms For Thoughts emphasized, is the FMP 13's $700 price. This cost makes thermal technology much more accessible than it used to be. Capabilities that once required a significantly larger budget are now within reach for more people, and this affordability is a core part of the FMP 13's appeal.
Ultra-Compact Size and Low Weight
Alongside the attractive price, the FMP 13's small size and light weight are standout features. The reviewer called these characteristics "outstanding," pointing out how practical such a low-profile and lightweight optic is. The offset sight doesn’t get in the way when handling a rifle and is very easy to carry and store.

Helpful Features and Straightforward Operation
Arms For Thoughts also found several aspects of the FMP 13 user-friendly:
- Display Options: The device provides multiple color palettes, giving users the ability to choose a display mode that works best for what they’re looking at and their personal preference.
- Secure Mounting: He noted the mounting system felt solid and appreciated that it features a standard RMR footprint for pistol mounting, and that a variety of other adapters for different platforms are available as optional purchases, allowing for easy integration alongside or in place of conventional gun sights.
- Straightforward Operation: The controls and menu were found to be simple and not overly complicated, avoiding unnecessary features that could be confusing in the field.
- Replaceable Battery: The convenience of a battery that can be swapped out was another plus, allowing for longer use with spares (though he did note the CR2 battery type itself could be a minor hurdle for some).
These positive points highlight why someone might seriously consider the FMP 13, particularly if budget and a compact form factor are top priorities.

Arms For Thoughts on FMP 13 Limitations and Reported Issues
Of course, no product is without its downsides, especially a first-generation device aiming for such an aggressive price. Arms For Thoughts pointed out several aspects of the FMP 13 that drew criticism or could be problematic for users:
- Touchscreen Usability: He found the touchscreen interface could be inconvenient or difficult to use reliably, especially when wearing gloves or in wet conditions.
- Complex Zeroing Process: The process for zeroing the scope was described as complicated, requiring pixel-by-pixel adjustments rather than a more user-friendly system.
Based on his hands-on experience, Arms For Thoughts also offered specific suggestions for how the FMP 13 could be improved in future versions. These included a better way to quickly adjust settings and a wider variety of reticle options.
Is the FMP 13 a Thermal Revolution? Arms For Thoughts' Assessment
Does the FMP 13 actually signal a revolution in thermal technology, like the title asks? Looking closely at Arms For Thoughts' overall assessment gives us a balanced perspective, but one that ultimately leans into why this scope is noteworthy.
The Core Verdict: "Compelling Option for the Price"
Near the end of his review, Arms For Thoughts summed up the FMP 13's trade-offs clearly. His key takeaway was: "Despite the stuff I don't like about this and despite the feat I think is missing, this is a very compelling option especially at the price point." This statement really gets to the heart of it – he acknowledges the FMP 13 has flaws, which were detailed earlier, but his concluding emphasis is on its strong appeal and value considering how much it costs.
What Makes the FMP 13 "Compelling" and Potentially Revolutionary?
What drives this "compelling" nature, and where does the idea of a "revolution" fit in? According to Arms For Thoughts' perspective, it's largely about groundbreaking accessibility and potential. The FMP 13 isn't about outperforming scopes that cost many times more; its significance lies in bringing functional thermal imaging to users who were previously shut out by high prices. Its ultra-compact size further adds to this, offering a level of portability that's remarkable.
It's this specific blend of financial accessibility and an incredibly compact design that positions the FMP 13 as a potentially revolutionary step. It’s about opening up thermal capabilities for everyday applications where it wasn't feasible before. While Arms For Thoughts did point out specific limitations, his overall sentiment highlighted the FMP 13's disruptive impact. He framed it as a first-generation product with "great potential," suggesting that while it may not be perfect now, its entry into the market at this price and size is a very positive development and a strong starting point for future advancements in affordable thermal optics.
