Mine is a .223 CZ 527 "American". It's very handy and surprisingly accurate. I'd definitely recommend it as a light "carry" rifle for coyotes.
The only negative comment is that the single-set trigger can be very light (lighter than you'd want on a hunting rifle, certainly not suitable for gloved hands). My solution is to simply use the regular trigger and to put up with the longer trigger pull. (It's really not too bad).
