Cool Mag – A Cool Fan Mounted On A Cool Magazine For Cool Operators

Behold the newest in operational tools for cool operators who operate in operations:



The COOL MAG from SUNPOWER SYSTEMS is a totally new and innovative way to air cool your rifle. Utilizing a 12v 30 CFM fan powered by two 9v batteries to push 18v through the fan.
The system is actuated buy a roller micro switch when the COOL MAG is put into the lower receiver.
The COOL MAG blows air throughout the rifle cooling the upper and lower, the bolt and the barrel.
Made from a Tapco mag this custom design is painstakingly made by hand with an aluminum plate fitted to hold the micro witch.
Yes the fan is big but we took function over aesthetics, do you want to look cool or be cool.

For the low price of $109 on eBay. Looks legit! haha

It’s your lucky day, the company will fit this system to ANY mag you want to send them.  According to the eBay page the custom cool mags take 3-4 weeks to make.  Wow, think of all the backorders and custom jobs they are going to have once the entire gun world knows this is available.

xzibit-cool-magAnyone buying computer fans and trying this themselves?

The science behind this is so solid, I bet even on automatic an ar-15 would stay at a cool 50 F under sustained auto fire from back to back mag dumps.

I just duct tape dry ice all over my AR, it works awesome.

Plus, if you’ve got water handy, you can create your own smoke screen on demand.

I think this stupid idea may have a secondary purpose. At the range and you want to leave but that rifle is way too hot to put back inside the case? Magfan to the rescue.

Not really, it probably wont do shit.


CHASE! October 18, 2013 at 12:47 am

I just throw my weapons in the horse troff, cools em down plenty


lolinski October 19, 2013 at 12:08 am

I really hope you dont do that, that ain’t good for the metal.


ENDO-Mike October 19, 2013 at 12:19 am

Bro do you not even quench? :P


CHASE! October 19, 2013 at 01:07 am

I quench the fuggin wrench.

Well if in fire fight and it can keep barrel cooler hell name of the game get off more shots price little high just to try but I may try one just for experimental reasons


jim bob October 19, 2013 at 01:49 pm

when i am in operator mode i pee on mine to cool it off.

I was thinking that was it’s purpose all along. Who would bother with it if the ammo was in the way of the airflow? I’d want the spot where the fan was to be completely cut out, not just skeletonized so it could still hold ammo, to maximize effectiveness so you could smack it in after a 3-gun stage or something to help keep your gun comfortable to hold. Jam it in a quick-access mag pouch on your back when the next stage starts. Paint the mag orange or blue and it’s a nice compliment to a chamber flag.

Considering how much restriction is in that path, though, especially if you close the ejection port cover like you should so all the air doesn’t just leave through there instead of going down the barrel, a squirrel cage fan would be far better for that, like the ones you see on high-end video cards. They have a lower flow rate but much higher static pressure. You could mount one right to the floorplate so you wouldn’t even have to give up a mag in the process, or if you have a used-up mag that doesn’t feed right laying around, shave off the feed lips and use that. Get a 12-V RC car battery rubber banded to the side of it, a switch and a fuse, and you’d be set for a whole day.

It’s all fun and games until someone loses a finger. ;)


JR Key October 18, 2013 at 03:01 am

I wonder if it will still make that cool Darth Vader voice when I talk into it??


05RC51 October 18, 2013 at 03:15 am

It was better than their first idea of a window a/c unit……


StarvinPilgrim October 18, 2013 at 05:36 am

Trying to decide whether this is real or you’re just blowing smoke up my ass…………………… ;)


Professor Hale October 18, 2013 at 05:48 am

I don’t see how this does anything but blow durst into your mag. None of this air can possibly circulate into the rifle unless the bolt is open. most of the heat is in the barrel and bolt carrier. What I really need is a cooler for the can.


CHASE! October 19, 2013 at 01:06 am

Blowing Fred Durst into your mag is a serious problem.


SittingDown October 19, 2013 at 05:28 am

Holly Durst would just read them a story.


czbeardly October 18, 2013 at 06:43 am

this is so retarded it hurts my face


Spencer October 18, 2013 at 12:24 pm

The stupid. It’s so bad it hurts.

Or maybe that’s just from me face-palming myself over and over.


Jim P. October 19, 2013 at 06:45 am

How many ways can you say this is a stupid idea.


Manny Fresco October 20, 2013 at 12:28 pm

The guy that makes this is the weird builder guy from the show the Colony, Michael Raines.


freddie g October 23, 2013 at 01:05 pm

Got one on a whim. It works well. Right about the range blazing zero. Correct about the water, lolinski. I run it for a minute with the dust cover open , then 5 minutes shut after a 100 rnd beta mag dump with a defendar fifteened and fail zero bcg’d windham cdi. Its not perfect, but its TWICE as fast as just letting it sit.


KablamO December 21, 2016 at 04:17 pm

Get in the gym and build some muscles so when you throw a water cool jacket on that byatch you can still shoot accurately.
