Looks good Mick.

I assume you carry it for the shotgun barrel, with the scope removed and put the scope on when required?

Same combination as one of my Tikka/Valmet barrels in 12g/7x65R. However mine is still awaiting gunsmithing to have the barrels fitted. As they don't quite fit without it, having tried it to my dismay. Slightly stuck on there for a little time.

Going by the ammo box, not the comment!
