AR-Fins Barrel Cooling Fins For Inside AR-15 Quad Rails

Had to double down on the posts about the same eBay guy that is selling the Cool Mag.  This is too good:

AR15-Barrel-Cooling-Fins-1

AR15-Barrel-Cooling-Fins-2

Made from .030 stainless chrome alloy that is practically rust proof, and YES it cools your barrel.
This serrated pattern is designed for maximum heat dissipation used in Hi-tech heat exchangers.
AR-fins are a two part system a primary rap around the barrel and a secondary sheet for added cooling.
It fits in all 6.7 inch Quad Rail Carbine Length 2 Piece Drop-In Systems.
AR-fins weigh only a few ounces and installs in minutes and LOOKS GREAT.
We utilize a precision crush fit using your Quad rail for maximum contact with the barrel and thus alleviating any possibility of rattle or noise from the fins.

If you don’t like this idea… bros do you even science?  

Sometimes the speed holes in your current quad rail just don’t cut it when it comes to heat dissipation.  If you’re not disappating the maximum amount of heat GTFO, and get you some fins.

The bid is currently at $40… get in! haha

Thoughts?

I’ll take a guess and say that whoever this guy is is probably a computer techie. He seems to be applying desktop technology (fans and heat sinks) to AR-15s.

if those were actually tight against the barrel with that crap you put in between your CPU fan and the CPU it might do something, maybe, but if it did it would need to be applied to the entire barrel, having a half cool barrel and a half hot barrel sounds like some interesting groupings

“We utilize a precision crush fit using your Quad rail for maximum contact with the barrel and thus alleviating any possibility of rattle or noise from the fins.” – which translates to “now it free-floats, now it doesn’t”.

Side note: JP Technologies has built a similar system for their barrels,except it is machined to fit specific barrel profiles, it still free-floats and has been used for years: http://www.jprifles.com/1.4.5_hs.php

I am just gonna wait for the USB 3.0 port for the shoulder thing that goes up

Combine this with the mag/fan and you’ll be…… “frosty” the super cooling techno ninja warrior operator from the future where such things are needed. You’ll be capable of operating in extreme temperatures of about 72 degrees or whatever the mall sets the a/c at…..

Steel is a terrible heat conductor. This is a barrel heat insulator, not barrel heat sink.

this hurts my face a bit less then the magfan… as Tierlieb stats, JP has sold a better version for ages, that sort of works.

That’s so wrong on so many levels. The JP rifle solution in much better, but the best solution for this “problem” is to take a heavy profile barrel, and AGGRESSIVELY flute it to increase it’s surface area as much as possible without sacrificing it’s integrity.

needs a fan in the handguard

Maybe a liquid cooling system with a circulation pump in the stock and copper piping to the barrel?

Steve October 18, 2013 at 09:58 pm

Would this qualify as a barrel shroud? We know how bad those things are…

Nice Simpson reference with the “speed holes.” Do you AR guys call them that a lot and I just missed it until now?

Haha thanks. It’s not a common reference as far as I know. Oy just popped into my head when I was writing the post.

I’d complain, but the lewis gun did it first. Given that history, I’m not sure I can complain that much, honestly.

Guys what if it work? Imagine we kain all make blowback operated AR so easy and cheap. And no gas operated AR anymore. In my house I’m making my own blowback 5.56 mm AR. just one thing, it over heats so fast. Why instead of CPU fan, why don’t we attach a mini cooling gas tank. Like a gas tank of air soft pistol.
