I have used the Talley rings on my CZ's and think they are the wonderful. They keep things nice and low. I have 550 FS rifles that have a little drop for better use with irons and the Talleys are great at keeping the scopes low for these rifles. That said, I now use an apeture on my 550FS in 9.3 and feel no need to go back to the 4x I had on it. I took a rear CZ ring and cut it off to use as a base for a ghost ring. I have also used the Warne rings and they are stout, but I did not like the heighth. I also tried the Burris rings which are ok, but med height so they put the 2x7 on the 6.5 up higher than I wanted as well. I am sold on Talleys and now use them on almost all rifles.
