Disabling AR gas tube?
If I buy an AR10 or AR15, how difficult is it to disable the gas tube so as to make the rifle no longer semiautomatic (to comply with laws if a law were passed to make AR illegal (a fair chance of that in the future in Minnesota)?
I would want to be able to do this myself, so that I could know how to re-enable the gas tube function to make the rifle semiautomatic again should a zombie apocalypse happen (grid down from cyber terrorists, etc) and I need serious home protection.
(FWIW, a decade ago I built an AR15 from parts but sold it soon after that. The barrel came with a gas tube attached of course. So I have some, a minimal amount of, gun parts experience for an AR.)
