GUN BARRELS GET HOT!

Heat has been the constant companion of every trigger pull. While it appears in varying degrees, it is ever present.

For the last 100 years, we've trained ourselves to avoid (or just outright ignore) this issue. Melted bags, burnt hands, bullet drift; the problems exist, but no one has done anything about it.

Like the Caveman of old, it’s time we put heat to work.

Heat is data. It shouldn’t be a wasted byproduct of sending lead downrange. It can be used to make better decisions around safety and accuracy.

Whether you’re a wide eyed novice, or a grumpy pro, nothing beats a visual indicator when it comes to safety. Why do you think Loaded chamber indicators are a thing?

No more guess work. Know at a glance. Caveman Thermochromic tech is the BEST way to harness your heat.
