Seems counter-intuitive with the topic at-hand. That’s why I built it as a piston upper, to hopefully solve that heat issue. Would like to fit a JP heatsink on the barrel but I just don’t think it would fit under that hand guard and with the space needed for the piston. |

Could the fins on the heat sink be trimmed down? |

Green Mountain makes some finned barrels, kinda odd looking and I have no idea how well they'd work but it might be worth a shot if you've got a FRT/binary or other happy device. http://www.gmriflebarrel.com/military-barrels/ar-15-/-m16-/-m4-rifle-barrels |

I was trying to find some quantifiable benefit on finned bbls and ran across this ; https://www.aimt.cz/index.php/aimt/article/view/1254/285
Would be neat to have TEG unit and fan that draws air through the rear of the handguard and blows it out the front in conjuction with the finned bbl . |

I'd love to get a hold of one of the FN double chromed barrels like Noveske sells and have it cut to 18" with rifle length gas, SDM profile and fluting behind a pinned mk12 gas block...

You know it's only going to be a matter of time before some nerd hooks up a GPU cooler.  Yeah, I know it defeats the purpose of a the RPK concept, but you know it's going to happen.

It's funny, I was just looking at battery powered clip on fans the other day to see if something like that was viable. Of course, fans are no match for water cooled:  https://www.ar15.com/forums/ar-15/My_Water_Cooled_Upper_Project/4-384217/
