Hey every one I was looking for clips on YouTube but couldn't find... Now what I would like to know is it necessary to remove gas block and tube for cleaning? Everything in the manual says to use powder lube? I'm a ballistol guy so is that ok? Anyways if someone could tell me what they do that would be great! Thanks a lot every one... Last thing do you oil up the piston tube?
 
I don't remove it all the time, but carbon does build up in there for sure. Any solvent should work decently to clean it. You don't need to over lubricate the piston as it will just burn off. But a light oil is recommended.
 
Depends on the ammunition you are using. If you are shooting corrosive 7.62x39 then yes you need to take it apart and clean it every time. If you are shooting non corrosive then you can clean the gas system every 1500-2000 rounds (or more if you want). The longer you wait between cleaning the more work it will be to get all the carbon off but it takes a lot of rounds for the carbon to build up to where it will cause a malfunction.
 
Hey cr5 I'm using norc surplus crate... I clean my guns after every range trip so I should be ok right?
And so piston is ok to lightly lube cause I also have Tavor and wasn't to sure, I though that would just collect more carbon and cause problems?

Norc is non corrosive so you should be fine.
Oil on the piston just burns and turns into more carbon, that's why they recommend using dry lube and some say to use nothing. Depends on the rifle and the coatings they use on the gas system parts.

This is correct so long as it is norc 5.56.

If it is norc 7.62x39 it will be corrosive.

I would not run either through such an expensive rifle.... x39 because ot is corrosive, 5.56 because of the possibilities of undersized projectiles "bouncing" down and out the barrel causing uneven wear.
 
Undersized projectiles don't bounce down the bore, they fail to seal it which allows gas blowby. Much worse is steel jacketed ammo in .223, the rifling can't take it in high volume. X39 and most .30 cals have rifling that can take the added abrasion of using harder jackets such as steel. For cleaning the XCR with non corrosive, don't worry too much about the gas tube and block for regular intervals. It doesnt foul heavily unless youre using some real poopy ammo. The less you remove the barrel the better. For short cleaning intervals some oil will last and make cleanup easier but for longer intervals dry is best. Just lube up to the chrome gas piston and you're gtg.
 
Ammonia is very effective at immediately neutralizing the evils of corrosive primers.

I have a Lab squirt bottle for the ammonia. I start with rinsing the chamber, muzzle down and let it pour into a bucket (or similar). I then give the gas block a squirt or two and let it run down into the bore. Back to the chamber again for a final squirt. I then use a Remington "Squeeg-E" pulled from chamber to muzzle to finish the job. I also dip the Gas Piston into the used ammonia in the bucket and then give it a wipe down with a clean rag.

Warnings:
Do this in a well ventilated area!
DO NOT MIX the ammonia with any other chemical!
You may flush the used ammonia down the toilet without any ill effects...
