...the barrel will be chrome lined or not?  I've searched other threads and other sites and have posted this question in other open threads, but I've gotten no response.  I know this may be a little early to ask, since Sig probably hasn't nailed down the final configuration for the rifle, so I'm sorry if I'm jumping the gun.  This will not be a deal breaker for me if it is not chrome lined, I still want one.  I think Sig may not chrome the barrel since the 550/551 doesn't have chrome lining, but one can always hope.  Thanks in advance for any info.

The SHOT prototype had a non-lined 1/9 twist barrel, according to other posts.  That may change for production models if enough people make noise about it.

Thanks Sparky.
