 Is it necessary to remove the gas tube when cleaning?

I have synthetic hand guards with the top guard screwed in place with a little red dot mounted on top. Is it necessary to remove the gas tube when cleaning the rifle? Is it more important for it to be removed when shooting corrosive ammo?

I'd rather not have to move it and possibly affect the ultra accurate 3 MOA I have dialed in. That, plus I'm lazy and it'd be great to get ya'lls approval so I don't have to unscrew it every time.

Thanks!

At some point, yes. You're going to need to remove it to check for carbon build up and such.

Every time....meh, probably overkill. Even if you are using corrosive. The big thing will be to check it with a good light to see if you are getting build up or rust.

I might recommend that you get a "bottle brush" or something like 45 cal bore brush that you can use to clean out the tube while installed. Just use lots of water and the brush at the same time till nothing else scrubs out.

my 2 cents.......

Thanks, it's my first AK and I've been using a 12 gauge brush to clean it out. I'll guess have to start giving it a hot water bath. That seems to be a popular cleaning method to get the salt out, especially in the places I can't reach.

Are you shooting corrosive ammo?

Make sure you throughly dry and lube and everything the water touches or it will quickly rust.

I'm shooting whatever is cheapest and most of that is corrosive.

I had to remove my gas tube when my shotgun 20Ga cotton swab broke from my cleaning rod and was stuck inside the tube. Now I just use a long strip of old T shirt soaked with with Breakfree to swab the inside of the tube without removing it.
Every time you remove the gas tube you take a chance of making it leak, as you will quickly notice they are installed tightly. And notice all that hot gas keeps the tube open and it's not really full of anything solid.

what leak are you talking about. ????
some AK gas tube has vent HOLES . Ak gas tube function more like a piston guide. there is no seal between the gas piston and the gas tube.

That's not a gas tube/cylinder. On the SKS, it is. Not on the AK.
It's just a mount for the upper handguard, and a shield/guide for the bolt carrier's piston.

If you assemble the rifle with the upper handguard removed, you'll note the piston goes into the gas block a skosh. That is the operational area, not the piece of tubing that bridges the gas block and receiver.
