I picked up a TOZ 78 bolt action .22 a week ago.
TOZ is a russian brand, that makes pretty nice rifles, for small money.
The TOZ78 is sold in the US as the Winchester Wildcat.
I took it to the range last sunday, after I picked it up, and fired a few rounds.
It seems pretty accurate and reliable.
There a several different versions on the market. Mine has a drum rear sight, where you can change the distance just by rotating the rear sight and get new sight blade in a different hight. You can adjust it for 25m, 50m 75m and 100m distance.
The front sight is set up like a screw, so you can change the elevation and the windage.
Here a link to some pics I took of my TOZ 78 (never mind the CZ75)
