Caveman Flare Mini: Temperature Sensor for Gun Barrels, Changes Color at 130ºF, Made in USA, Fits .675" to 2" Barrels, Easy Toolless Install, Improves Shooting Accuracy and Safety

A great idea to prevent overheating your rifle barrel...especially with today's high-power ammunition loads!

I got two of these before & they work as they should. So I got 2 more. One more for me & one for my son as he also like the idea of not taking a chance on overheating the barrel. We do a fair amount of plinking when at the range.

Everyone knows maintaining a healthy barrel is important. Keeping it clean, lubricated, and ready to shoot loads is common knowledge, but did you know vigorous shooting comes with its own hazards?This is where this ring comes in. Slide it onto the shaft of your barrel, do your thing, and it changes color when you've gone from "good tempo" to "too much! danger!" This is important not just for maintaining accurate shots during long sessions, but also when you're putting your package away, as damaging your bag or sac from a hot barrel is never a welcome feeling.Price is right, stays where I want it, works well and without issue and can accommodate different thicknesses, and after all is said and done it keeps me aware of when I'm ready to move to the next stage (usually, the recovery period.)

I originally got this for my boyfriends rifle can (2”) and it was nice for the first 10 rounds. It changed color from brown to bright orange after the first mag which was reassuring. When he was on his 3rd mag, we noticed the band has snapped off and flew somewhere towards the range. While it was disappointing- we did push the band to its capacity.Customer service reached out and was amazing! They even refunded me for the band. They listened to my experience and reassured me that the band is not designed for rifle cans just yet! However- they are working on it!! I’m super psyched to get another one once the bigger bands come out!!Wonderful experience!

Works just like it should

Whoever invented this is brilliant! It changes color when your barrel gets hot and visually reminds you to let your barrel cool down before you burn out your barrel.

Boss is an SOT / FFL7 and has plenty of form 2's and these get plenty of action, apparently. They look cool and have a nice....firm...grip on the shaft.
