"We are way way ahead of you. We haven't used the 1/10 twist for about 1 year. So if you order a 6.8 Kit from us not only do you get the 1/11 with the SPC II chamber but we also do the 4 groove which many don't. Many use the 6 groove which is not as good.

So, I think I'll be placing my order for a 6.8 conversion kit.
