“I love these!” –Josh

“This is a quality product”–MrzBubblezZ

Works great would recommend. –some_kid6

“Love your product by the way, threw it on my AR this weekend for the first time.”– Chellz99

“Great product, wish more people knew about it, safety owns” –David G.

“No regrets on this purchase. Super cool when the color changes” –bootstrap-

These work well and let you know if you’re gonna melt your hundred dollar gun case 10 minutes after dumping a few hundred rounds or not –Cognito_mode

I love mine! Just yesterday I did a cool test with it. I got a Caldwell AR barrel cooler so I don’t burn up my hands from overheating. I would shoot 60 rounds, insert fan, switch to 2nd gun, repeat.
The temp indicator would be at a grey/orange color when it was time to use the gun again. Went through 600 rounds in 45 min. Also I was confident I wouldn’t melt my bag when I packed up this time. –PhairPharmer-

“Get one. I slipped it under my hand guard but can still see it when it changes to orange. Really nifty gadget. This Industry needs more innovations like this” –Newsand…

Awesome product. Support them and buy with confidence. –Marines691

I was out shooting in the desert, and had put the gun down for at least half an hour. But it was still way too hot to touch. I had to grab gloves just to put it in the truck to cool down in the A/C.
Luckily I burned my hand when I first grabbed it, so I knew not to burn the other hand.
These are stupidity guards. I need it. –EarlyForest

“Awesome little gadget, let’s me know when my barrel is down to a safe temperature to store it away without risk. Changes to a very vibrant orange that stands out well against the black barrel, even when its tucked under my handguard.
Just buy it.”– Lee B.

This is a really cool product guys. Good on you. –Lowtiercomputer

“Ordered one and man this thing is cool. Great product”– Marines691

I finally got to test mine. Even though one was discounted ring (blem if you will) it lit up orange saving me from burning the shit out of my hand –dirtyboots702

“Just tried mine out for the first time Sunday. Worked like a charm! I had forgotten I had put it on, then the Gf noticed the bright orange and pointed it out to me. Also spurred the conversation about keeping paws off the hot barrels as part of the safety talk. Solid product!!” –SwedishRedneck

These things are little gems. Great for keeping barrel cool during slow fire. Great again while waiting to pack up. Don’t have to hover around touching the back of your hand to it every few minutes.  –tavelkyosoba

“These things are pretty cool. Definitely worth at least getting one for how cheap they are”– PhairPharmer

“Easy to install, does the job well, and doesn’t get in the way of the gun aesthetically or functionally. A must for any rifle you’re mag dumping with before storing in a case. Fast shipping and fair price, I’ll be back for more.” –Marcello A.

I have to say, these are awesome. Picked a pair up a couple of weeks ago for my new pistol build for the sole purpose of justifying echo trigger mag dumps. –sqnztb

“These people are awesome. Just bought them and forgot to put in the code. I thought oh well it’s not that big of a discount. Just got and email that they did a partial refund so I got the better price anyways. That’s great customer service. I might buy some more now”– Perrone21

I know when it’s cool enough to go back into the case after a range trip. (I’ve melted foam / case material. Not fun.) –stonebit

I picked one up on your last sale after a hot-barrel-grab ended a range trip early. When you’re used to shooting slow precision groups with a cold barrel, it’s easy to forget that a mag dump will make things screaming hot.

The color change feels like magic. I 100% would shill for you guys.

“These are awesome. I got a handful in the “wrong orange” sale, and love ‘em.  Bonus, show off your rifle mood ring to your range buddies. Magic” — _Franz_Kafka_

Have a couple of these. Such an easy thing to throw on there and provide a solid visual DONT TOUCH for seasoned shooters and newbies. Unintended bonus I learned last time out… works if it’s hot just from the sun. That barrel can get too hot to grab just from sitting out in the sun on a blazing hot day. Unexpectedly saved my paws! –SwedishRedneck

“I love mine. I use it on my AR”– Kimber J.
