Cutting a chrome lined barrel

[B4forever]

Are there any possible negative effects to cutting and threading a finished chrome lined barrel? I thought i remember reading somewhere there is a possibility of chipping the chrome lining.

I cut a crome lined 20" barrel down to 16.5" drilled out the gasport, recrowned it, and threaded it for a muzzle brake. No ill effects.

Lest you’re going to ruin some unobtainium HK shit…why bother instead of re barreling?
