View Full Version : Is this bad to do this to your AK?

I had an idea since I like to put a lot of rounds down range but I hate when my barrel overheats.

Do you think it's a good idea to put heat exhaust wrap around my ak barrel under the gas tube and in the lower handguard?

Please give me your opinion before I do something stupid

If I understand you, you want to wrap the barrel so that you can't feel the heat, as opposed to finding a way to dissipate the heat faster?

If so, I wouldn't recommend it. A barrel that gets hot is going to be less accurate; if you're shooting an AK you can't afford to lose any. :p Also, containing the heat is only going to extend the cooling time, and it could possibly harm the barrel if it got higher than its design parameters.

Wrapping your barrel would cause the barrel to heat up faster, probably get it hotter given the same amount of use, and slow its ability to cool off. Why would you want to do that?

Why do you think they made a forward grip lower hand guard? :D

That heat you feel coming off your barrel is a good thing, that is the barrel cooling down. If you put something like exhaust wrap over the barrel you are insulating the barrel and it will heat up faster and stay hot longer, though you will feel less heat on your hands. If all you care about is the comfort of your hands then ya wrap away.

if i didn't want to feel the heat I'd wear gloves, no pun intended

my thinking is that it would abosorb the heat making the barrel cooler a little bit longer

is it bad to pour water on it to cool it down?

There is no free lunch.

These tapes are used to keep the interior engine bay temps down. Heat wash is an issue that can raise intake temperatures that rob horsepower. Wrapping the exhaust means you are limiting by some degree the radiant heat of the exhaust manifold in the engine bay. However your headers will get very hot, but then headers are meant to be very hot.

Applying this to rifle barrels is actually the wrong direction to go in. You want your barrel to wash off its heat more actually if possible. Think it through.

bend it so it is a 'spikey' circle, like a sun symbol and wrap them around the round parts that get hot.

Thus they would be going the opposite direction of this Thompson and going same direction as "fluted".

But note this guy says it don't do much good, but I think it would conduct a lot of heat.

I know there are some old school machine vibs that had water cooling barrel shrouds so it's not bad in every instance. But I imagine that cools evenly. pouring water on there might not be a good idea.

Out of curiosity, how fast are you shooting it? These barrels were made with full auto at 600 rnds/min in mind.

It depends on how hot it is. You don't put it on the car engine, as there're other things there that can be ruined by water (contacts, etc.), and because you gotta be careful with all the hot steam that'll produce. However, it shouldn't affect heat treating and tempering of the metal, unless it's at the temperature where it's affected whether you put water on it or not.

You wouldn't want to touch the barrel after a full auto magdump, either. If you're at the range and your gun is cool enough to touch with a bare hand, you need to shoot some more ;)

don't pour water on your barrel, it might cause the steel to fatigue or crack. Even if you are shooting a lot of rounds through your gun, isn't that kind of unnecessary? AKs are horrible when it comes to accuracy, are you just looking to spray? IMHO, I like shooting my guns, not spraying.

ive got my ak pretty hot before its easy in just four 30 round mags fired off in 2 minutes

it takes a while for it to cool

That you wouldn't, but I wasn't suggesting touching it, either. That's what handguards and forward grips are for.

.... OP jus wait for an iceberg so both you & your AK can SINK like the TITANIC ....

... and after adding the 'heat exhaust wrap' how about a cappuccino cup holder next to that barrel, jus to keep that succa warm while shooting ... :43:

... Even if you are shooting a lot of rounds through your gun, isn't that kind of unnecessary? AKs are horrible when it comes to accuracy, are you just looking to spray? IMHO, I like shooting my guns, not spraying.

wha ?!!! ... AK's are 'horrible for accuracy'?! Just exactly who's doing that kinda shooting? Gotta be someone like THIS GUY:

Too hot to handle? Just whip out the wanger and take a leak on it. The smell of burnt urine really gets the nasal passages clear and clears out the shooting lanes next to you:rofl2:

You want to remove heat from the barrel. Air works well but a liquid works better, the problem is unless you have a constant flow of water to remove the heat, you risk thermal shock to the barrel. That could warp and or cause any defects in the barrel material to show up pretty quickly. Pour hot water on a cold winsheild with a tiny crack and see what happens. Your best bet is punch more holes in your handguard to allow the air to remove the heat.

Just so its out there. most header wraps attract water and moisture.

haha yes i did and i almost had to take summer school for it, almost failed. however, the following years when i took bio and anatomy/physiology, i passed every test and was one of the top students in my class. i just had a bad phys sci teacher, RIP his soul tho

Do NOT wrap your barrel or just dump water onto the barrel, you know unless you wanna screw up your gun.

Don't do it! Your rifle is air cooled so if it gets too hot just stop lock the bolt back and let it sit for 5 minutes or so. Remember yourin California and not in Alaska

You realize we are talking Ak's here... Gonna go on a limb here and bet the OP doesnt have a notched safety lever.

Did you ever notice in the photos of guys shooting AKs that a lot of them have a rag in their left hand. This is to keep your hand from burning. I have tried it and it works quite well.

Gil, its an AK. Run it until it catches fire. Glove your left hand if heat begins to alter the way you grip the front of the rifle.

.....and dont pour water on your rifle.

How do you think they get cooled? Water flows through the engine.

lol yeah i don't know about that guy. it really depends on how hot the engine is and how cold the water is.

I've squirted the hell out of so many engines with simple green and/oil eater while the engine was still running, then i took a garden hose and sprayed the whole engine down while the engine still running. blew it dry with compressed air, with engine still running. BTW it really cleaned the engine up

sold that car on CL a couple hours later

Buy another AK. Shoot one while the other cools down.

I've had the handguards bubble up when I ran one thru a test.

Why don't you just add a rail system to the handguard/gas tube, and run a vertical grip>

i most certainly WILL buy another AK. I got my eyes on an arsenal sgl21. still want to check out a couple shops in my area tho.

Don't throw cold water on a hot barrel. It's in no way the same as cold water on a hot engine (which you should also not do).

Maybe you can look into the Magpul VG option, don't know what to say, that spot always gets hot.

There was an episode of Bizarre Foods set in Alaska where they'd prep a meal (in tinfoil, iirc?), stuff it in the engine compartment of their snomobiles, drive off and it would be cooked perfectly once they got to their destination.
