AGM Rattler TS19-256 Review: Best Thermal under $1000?

Having recently written an article on the best night vision scopes available, I identified the AGM Rattler TS19-256 as the best premium option in the still affordable range. 

It seems to have struck a chord with many enthusiasts who are on the lookout for a thermal imaging scope that balances price with performance. So, how does it actually fare in practical, real-world conditions? 

Does it beat out the thousands of dollar versions out there? Or is it just a good beginner’s thermal?  

I’ll answer these in my in-depth AGM Rattler TS19-256 review.

[Update] I originally reviewed the AGM Rattler TS19-256 thermal imaging scope last year, but recently I had the chance to use it extensively again. After putting it through its paces and using it in various conditions, my thoughts on the scope have shifted. I wanted to update this review to reflect these changes. So, read on to see what’s changed in this updated article.

AGM Global Vision Rattler TS19-256 Specs

Before we get into my review, let’s start by discussing what the AGM Rattler comes with, its specifications, and some of its features. 

The AGM Rattler TS19-256 thermal imaging scope has a resolution of 256×256, which allows users to effectively identify and engage targets with an adequate level of clarity. Although not as crisp as some high-end models, this resolution is sufficient for most hunting and surveillance applications up to a range of around 150-200 yards. They also fit the scope with a 19mm lens that contributes to its overall capabilities, making it a solid entry into the thermal scope market.

When it comes to refresh rates, the AGM Rattler TS19-256 operates at 25Hz. While this may be a bit on the slower side for tracking fast-moving targets, it is acceptable for moderate-paced activities, like hunting or scouting. Additionally, the scope provides a variety of reticle options, offering flexibility for users to choose according to their specific needs and preferences. However, the ability to assign particular reticles to different profiles is currently lacking and could be a potential area for improvement.

In terms of power options and battery life, the scope uses two CR123 batteries. It also features a USB-C port, which allows for an external power supply, thereby extending its operational time. While the CR123 batteries do offer limited continuous operation time, the USB-C port offers versatility in terms of extended use, albeit with a slight compromise on portability. The scope can detect heat signatures up to 900 yards away. Although, the effective identification range is considerably shorter—around 150 yards for smaller targets and up to 200 yards for larger game.

My Review of the AGM Rattler

Before I even mounted this compact thermal imaging scope onto my rifle, it already impressed me with its specifications. The AGM Rattler TS19 thermal image riflescope offers a resolution of 256 and a 25 Hz refresh rate. These specs, coupled with a 12-micron sensor, immediately caught my attention. The 19mm lens was also a nice touch, striking a good balance between field of view and magnification. When you consider these factors alongside the scope’s pricing, you’re getting a considerable amount of bang for your buck.

First Impressions and Setup

Out of the box, the AGM Rattler night vision scope comes with a lens cloth, making it easy to keep your thermal rifle scope clean. Setting up the scope was straightforward; however, the rifle mount did raise some concerns. Based on reviews and my experience, the mount is perhaps more suited to lighter recoil rifles.

The Feel and Operation

When it comes to operation, I was quite pleased. The scope is relatively lightweight and doesn’t make your rifle feel cumbersome. The turret feel is adequate, but not exceptional. Button functionality could be better, but they do their job. The user interface is straightforward, allowing for relatively easy boresight adjustment.

Features

Where this thermal imaging rifle scope shines is its feature set. I was delighted to discover the scope’s internal recording function. This feature allows me to capture my hunting experiences without any external equipment. This feature significantly increases its value for me. It also has an onboard Wi-Fi module, enabling real-time sharing of your experiences. I found this particularly handy when hunting with friends who also had thermal scopes.

The range of color palettes like white-hot, black-hot, fusion, and red-hot makes it easy to adapt to different conditions. Switching based on what’s in front of me, whether it’s a foggy field or a pitch-black night, is quick and smooth, really boosting visibility. I also appreciate the defective pixels correction feat, which keeps the image crisp by automatically fixing any dead spots.

The picture-in-picture mode is another game-changer. It gives me a zoomed-in view without losing my broader field of vision, letting me zero in on the target without sacrificing situational awareness.

Power and Continuous Operation Time

Another aspect that I found somewhat mixed was the battery life. The scope runs on CR123 batteries, and in some cases, they can drain quickly. However, I circumvented this issue by using an external power supply capability via its USB connector. Still, this does somewhat dampen its portability. I’d recommend going with a good-quality battery pack for better continuous operation time. On the plus side, the battery compartment is well-designed, making it easy to swap batteries when needed.

Image Clarity

Now, let’s talk about the elephant in the room: image clarity. While the 25 Hz refresh rate and 256 resolution are certainly respectable, the overall image quality doesn’t quite measure up to high-end scopes like the ATN Thor or a $6k Pulsar. Beyond 60 yards, the image does tend to lose its sharpness, which is something to keep in mind. However, we expected this considering its price range. For shorter ranges, the image quality is much better, allowing for effective identification and tracking of targets.

Range and Versatility

While the AGM Rattler is not a scope for long-distance shooting—its effective range is around 150 yards—I found it more than sufficient for most of my typical hunting activities, from hogs to coyotes. Night vision was effective, and it particularly impressed me with its performance under harsh environment conditions.

Compliance and Export

It’s essential to note that, like all thermal imaging rifle scopes, the AGM Rattler falls under specific export regulations. Always make sure you’re compliant with the laws if you’re considering taking this scope across borders.

Final Thoughts and Ratings

Summing it all up, the AGM Rattler TS19-256 offers a considerable amount for its price. For those new to thermal scopes, or even for the more experienced user looking for a ‘buddy scope,’ this could be the perfect unit. It’s an excellent product for its cost and functionality. Just remember to have extra batteries or an external power supply on hand for extended use.

If you’re looking for a thermal scope that offers value, convenience, and adaptability, the AGM Rattler is worth considering. I’d say it’s a great stepping stone for anyone looking to delve into the world of thermal imaging scopes without investing several thousand dollars right off the bat.
