Mirage URL Chassis

[Butler12]

Just wondering if anyone was running one of these chassis I am considering one for a Stiller Tac 338 switch barrel build . I see they have a 4" magazine that comes with there heavy chassis .
They are a expensive chassis and I was tossing up between this and a McMillan A5 supermag with adjustable comb & butt . Are there any real world advantages with there centreline design?

I own one in a 6.5cm and I’m very happy with it. I’ve shot several other calibers (7/300, 338LM)in their chassis and their centerline design the recoil is noticeably improved. The muzzle hop especially.
