So I am building a purpose built comp rifle for next season. When deciding on contour, I came across the Bull contour from x-caliber for their AR-10 barrels. As a heads up, I'm using a CRB blank, not an x-cal. Craddock is doing the barrel work. But just to see how it looks on a rifle, does anyone have an X-cal ar-10 bull contour barrel? Maybe 22"?
