...one of our gunnies in another thread had stated he didn't own an AR; I commented on what he is missing. But then it struck me, I have never cleaned the gas tube on my carbine. 1000's of rounds and I have never cleaned it!?

What do you guys do, wait for restrictions to let you know when it needs to be replaced?

Soak it in solvent (tray)?

Run a pull-through/bore snake thingie?

Feel free to chime in on what you guys do to keep your AR's running true.
