Caveman
Caveman barrel temp indicators install on your rifle barrel and show you when it is heating up, so you know where you stand before a follow-up shot. Caveman Products builds them for hunters, and they are made to take the knocks of a season in the field.
The Flare lineup
The Caveman Flare is the main line, and it comes in a few sizes so you can match it to your barrel and how much room you have:
- Flare customizable 3-pack, for setting up more than one rifle or keeping spares
- Flare 5-pack, for a whole safe of rifles or a shooting group
- Flare Mini, a smaller indicator for slimmer barrels or a cleaner look
- Flare Micro in orange, the smallest of the Flare models
Caveman also makes The Spark Series, which sits alongside the Flare line.
Why barrel heat matters
A hot barrel can shift your point of impact, and after a string of shots on a group of hogs or a sight-in session it is hard to judge heat by hand. A barrel temp indicator gives you a quick check without touching steel. Find more options in our barrel over-heat indicators section.
Frequently Asked Questions
How hot is too hot for a rifle barrel?
There's no single number, but once a barrel is too hot to hold, your groups usually start to open and point of impact can shift. A light hunting barrel heats up fastest. A Caveman Flare installed on the barrel gives you a quick check between shots, so you can wait out the heat before a follow-up.
How accurate are barrel temperature indicators?
Treat them as a quick gauge, not a thermometer. Temperature strips and indicators read in ranges, which is all you need to know if your barrel is cool, warming or hot. That's the job a Caveman indicator does: a look at the barrel tells you where you stand without touching steel after a string of shots.
How does a barrel temperature indicator work?
A temperature strip uses material that changes color as it warms, so you read heat by looking at it. A barrel indicator does the same kind of job on your rifle: it sits on the barrel and shows when it is heating up. Caveman offers the Flare series in several sizes and The Spark Series.
Where can I find a barrel temperature indicator?
We carry Caveman's lineup here. The Flare customizable 3-pack and the 5-pack cover several rifles, the Flare Mini suits slimmer barrels, and the orange Flare Micro is the smallest. The Spark Series rounds it out. Orders ship free to US addresses, with no sales tax outside Illinois.
