Questions about 6.8 AR

[greywolf2112]

1 - Anyone make a chrome bolt for the 6.8mm AR?

2 - Is the bolt carrier group (everything but the bolt and extractor) on a 6.8mm the SAME exact thing as the one on a 5.56 AR? Meaning, if you already had a 5.56 bolt carrier group, could you then just use a 6.8mm bolt with it in a 6.8mm AR upper?

Thanks!
