I agree, Ive got the muzzleloader barrel, 22-250 bull barrel, 300 win mag, 15inch 243 pistol, 15 inch .204 ruger pistol. The scopes mount to the barrels, so when you remove it and put it back on it is still zeroed since the scope doesnt move. To change barrels, all you do is remove two small screws from the forend, and push out a pin, takes about a minute to swap out a barrel. I love it, you wont be sorry.
