Thermal optics are fantastic for those who hunt nuisance species like hogs, but they’ve always had one huge problem: the price. A typical thermal rifle sight has traditionally been in the same price range as a small car, which puts it out of the reach of the average shooter. The reason for that price is that thermal optics have usually been marketed primarily towards the military, with civilians a secondary consideration. Now, FLIR is introducing a line of thermal optics designed and priced specifically for the consumer — the R-Series.

Unlike some other watered down versions of military-intended products, the R-series optics seem to have all of the same bells and whistles that you would expect. In addition to the optic itself, the the scope features a USB port that will not only charge the optic, but allow you to record the video to a secondary device. It also seems to work really nicely — I had a chance to test it out at the Crimson trace Midnight 3-Gun Invitational last weekend and it was a joy to use.


The base model RS24 ($3,499 at Optics Planet) offers a 1x thermal sight with no digital zoom, and the only thing you gain with the increased price tag in this series is increased zoom capability. So really, for hunting things in places like Texas, the RS24 is enough scope for your needs.


The sight uses a standard ACOG mounting system, and comes with a LaRue mount from the factory. If you want to change mounts though, the ACOG mounting design is something that a number of different companies support, so finding additional options should be easy as pie.

The only downside: the scopes aren’t built as tough as their military brethren. The biggest caliber the FLIR reps recommend is .308 Winchester and even that has only been tested to 10,000 impacts. Of course, 5.56 can be handled with ease, along with 300 BLK, but the bigger calibers would require one of the higher-end series scopes to work for any length of time.

The R-Series launched at SHOT Show this year, so they’re still very new to the market. But at this price, even I’m tempted to pick one up.

      • Yup, I usually get ripped on because I like my guns naked. No optics, lights, lasers, grips, any of that stuff. I don’t rip on people that do like it, to each their own, but that’s how I was trained. Too keep it simple and rugged for the worst case scenario. So Iron sights and a bayonet. Only attachments I want. However the fact that stuff like this is becoming more readily available for regular people is a great thing. Keep the prices coming down.

        • Yep, I can spend 3,500 bucks on a night vision device that, not surprisingly, only works at night for my 450 buck rifle or I can(and did) put a 200 buck scope on my rifle and call it good.

          I’m far enough along in years that my hunting rifle wears glass.

  1. I guess I’m not part of the masses. I won’t spend $3,500 on a gun, much less a sight. What’s the likely per hunt cost of this thing?

    • This…

      Seems like all of Leghorn’s reviews these days are of shit most of us can’t get/own or can’t afford. If we want gun porn, we’ll buy print mags so we can get pictures taken by better photographers…

    • One of the many hats I wear is that of an infrared thermographer, and I use a FLIR infrared camera for work. When it comes to IR imaging equipment, $3500 is very inexpensive, and FLIR makes top-tier IR imaging equipment.

      • Heck, the car I drive cost me $1500. Runs just fine.

        I also shoot deer at 500 yards with a $350 Walmart rifle/scope combo. I do just fine on the frugal side of life, thank you.

        Thermal imaging is drooly, but there is no way I will buy it unless it can be found for $500 or less. Its how I roll.

        • I hear you and most of my friends are that way.

          On the other hand, I’m about to start carrying a $3k pocket knife. 😛 When I was a kid someone told me to buy quality and you’ll only cry once. I’ve taken that advice to heart. As a result, I may not have things by the time other people do, but when I get mine, it’s better.

  2. There different sized detector arrays, up to VGA, so that is one thing more $$ gets you. No mention of noise/sensitivity (NEDT), but it’s probably ITAR limited to be not so great, which would limit performance out at longer ranges. 30Hz frame rate is probably less an issue for a TWS than for goggles, where you need 60Hz to avoid motion sickness.

    Expect these to continue to drop in price as next generation 12-micron pixel arrays ramp up.

    • Yeah, I know it’s sexy Woodhouse. That’s why I bought ten. Now arrange those by color, from black to slightly darker black.

    • Thermal imaging equipment works based off of surface temperatures. Different materials absorb, reflect, and radiate heat energy differently. A bare steel target would appear as a mirror to infrared due to its low emmissivity and high reflectivity, which would contrast with a non-IR-reflective background. A coated steel target wouldn’t be so reflective due to the coating. Since it would reflect and emit IR radiation differently than the background (trees, dirt, etc.) it would stand out.

      • Haha, my question was only half serious, but thanks for the detailed explanation. I was just imagining guys with battery powered hair dryers standing in front of all the targets in between shooters.

    • Actually, that would be bad ass. Kind of like tank gunnery where heated targets pop up and you have to engage them with the appropriate gun, i.e. 120mm cannon, .50 cal, coax machine gun. They could have a “range rifle” and drop a stage into this next year. Both Crimson Trace and FLIR are HQ’d here in Oregon. Someone make this happen.
      The more I think about it, the more fun I think it would be.

  3. Anybody have some great links on how to hack a known-good solution using off the shelf cheapo stuff for non-serious fun?

    Like for back yard rat and coyote suppressor blasting….

  4. $3500 Bucks is considered priced for the consumer??…Some people are out of touch with reality..even half that price is a bit of a stretch.

    • It’s relative to what it is…. A $3500 grilled cheese sandwich would not be very exciting, but if this is the cheapest thermal scope on the market, well that’s interesting. And if it’s still more than you can spend then you just aren’t going to get a thermal scope and this article wasn’t written for you (or me).

  5. Honestly, most hog hunters will only need night vision; the only difference within hunting ranges is that thermals make it ridiculously easy to pick the hog out of the background, but for 3-4 times the cost of a gen II scope, that advantage doesn’t seem worth it. Any sort of night sight is an improvement over just looking through a dark tube, and I would prefer to get the cheapest night sight that will withstand whatever caliber I choose to hunt hogs with. I am of the school of thought that believes that you should never spend more than your rifle’s cost to put glass on top of it… Then again, I suck at shooting long range.

  6. That would be great for my pistol. For clearing the room at night.

    You know, for the kids sake(tm). I’m never going to grow up…

  7. Thermal optics are also helpful for detecting if the ATF were shooting at US citizens when later they claimed they were not.

  8. About time the made one for shooting. Have been producing “low cost” thermal for FD (and cops) for a couple years. Pretty good stuff and certainly very competitive in cost to performance compared to the existing options.

    For the capability all their stuff is quite reasonably priced.

    Market is not for hunters. Sales will be to the prepper/zombie market (and perhaps Texas hog hunters).

  9. Some Nightforce and US Optics scopes are in this price range….which a lower priced Leupold could match just the same. So i’d rather spend the big bucks on the FLIR… at least it gives you a unique capability.
