RE: CZ 550 FS 6.5x55 Swede
That is a sweet looking package. I myself have always like the look of the full length stock, and also know of the beautiful balance that they can offer. And, the 6.5 X 55 in a modern day action should be capable of an extremely wide range of purposes.
I know you said you'd like to leave it as is, but if I were ever to obtain a beautiful package like yours I'd scope it with some quick release rings/mounts so switching back and forth to the irons or scope could be achieved.
Congrats on a beautiful rifle.
