Is the gas chamber chrome lined?

If its of no benefit why are bolt carriers coated in NiB or TiN?

An attempt to improve things, Marketing, point of difference. For you to do it after purchasing however, I am just saying that the carrier will work as is so I am wondering the cost/benefit. If the benefit is the satisfaction of tinkering or having a point of difference, or even a catalyst for discussion like on this forum then all good. As for practical benefit over what it already does, what do you think?

I would put that $155 towards a better barrel.
