Great barrel, would/will buy again
I got the 26" 6.5CM in Comp. Contour. Puts the balance point just in front of the magwell (MPA Comp chassis w/ bag rider, 1 front MPA weight, 737 action, and Razor scope). It clears the MPA chassis, but it definitely fills it up. If your using anything else I would measure twice. We'll see how it holds up over this next year, but right now, it looks like I'll be buying another when I burn this one out.
