I bought this as part of a plan to build a 6.5 SAUM. As is often the case, plans changed. It is a new Mullerworks stainless cut-rifled, modified 4 groove barrel blank in 6.5MM. It is a Rock #4 contour which is close to a Remington mag contour as it measures .655 at 26” and is 1-8.5 twist. It is unmodified/umchambered. The length is 27". $325 shipped and insured lower 48, AK and HI a little more.
