Anybody know anything about that^? All the info I find online only talks about the 5.56 version. I've heard 1 in 11 is the best twist rate for 6.8 but this comes in 1 in 7. Does anybody know how the 6.8 performs with that kind of twist?

1:11 is the preferred twist rate for 6.8 SPC. There are variants like that one and the Noveske, which is

probably the cream of the crop for 6.8 rifles, but there are many good ones that are less expensive,

like Rock River Arms, Stag, AR Performance and others.

Are you wanting to build an SBR, because that one is a 7 1/2 inch barrel?

What are you wanting to do?

I am looking at a 6.8 SBR build. I really like that kit because of how much it simplifies it. I get the lower, I get the paperwork, I get that kit.
