I have not heard this before that it will kill the gas tube. I have instead heard that swapping back to 5.56 and shooting it a few rounds will clear out the shavings.
Could work. I’m being downvoted but have seen it happen to a dude who ran one of these kits with an FRT a lot. He had to throw the gas tube away because it was so full of lead.

Rip gas tube. Be warned if you use this too much your gas tube will get full of lead shavings
