OTB Suppressors - Extreme Heat?

[UnckleBob]

I get to do most of my range time with my rifles during the N Texas summer where 90+ degree heat is the norm. I don't shoot AR's or mag dump into the trash. I shoot bolt action rifles (223 to 7BC) at a moderate pace. But, everything gets hot fast.

Suppressed or not, I do struggle to keep barrels cool. From what I can tell, my AB Raptor 8 seems and the attached barrel seems to cool down faster than my traditional suppressors. That seems counterintuitive.

Have any of you tested OTB barrels for heat dissipation?

I'm interested to see how it works out this summer as well. Have an og6 and rok22 to play with soon.
