Picked up a CZ452 today from the LGS. It's an American so no sights but I was given an Anshutz globe for it.

I plan on shooting competition with the rifle so I'd really like to get this on there along with a decent rear sight.

I'm not so worried about the rear, I just need to find a rear that will work with my left hand bolt.

But how can I attach this globe to my barrel? Do I have to have the gunsmith install something, or can I get some clamp on something or other?
I really like this globe but the lense is cracked, so have to factor that replacement inn too.

Thoughts?

Have your local gunsmith drill and tap for the sights appropriate mounting block. Find which block you need by looking up the sight by model number.
