Well, I've had the CZ-527 204 for a year and a half now and I absolutely love it. The 527 American is a short, light rifle, perfect for coyote calling and the 204 is a great cartridge. I recommend the rifle and/or caliber to anyone.
The single set (adjustable) trigger is great. Push the trigger forward until it "sets" and you have a hair trigger that is just a few ounces (perfect for sighting in) OR use the trigger conventionally (currently at 2-3 pounds).
There are a couple of mod's that I felt it needed:
First mod I had done is the bolt handle. Sent it off to James Calhoon
http://www.jamescalhoon.com/ and he milled down the bolt so it will clear the ocular lens of a scope that is mounted on Med rings. (Rifle came with High rings for this reason).
Second mod is the magazine. Sent the trigger guard/magazine well, magazine release and one magazine to Roy Bertalotto
http://www.rvbprecision.com/articles/11/cz-527-rifle-magazine-conversion and he milled down one magazine and the trigger guard to allow a shortened magazine to fit nearly flush. Most folks won't purchase a 527 because of the magazine protrusion. The price you pay to have a nearly flush mag is a 3 round mag vice 5 round HOWEVER, the standard 5 round mag (which is shown in the second pic) will still work.
Before:
After: (and a Double Coyotee call & 5 round mag)
I've only taken it hunting a few times and it's put an end to one coyotes life but I plan on taking it on a serious 2 week coyote slaying expedition to west Tx when I get back to CONUS.
I'm about to top it with a VX-III but I can't decide between the 3.5-10x40 or the 4.5-10x40. The sensible side of me says that the 3.5-10 is the better option because %75 of the coyotes and foxes that I shot were < 50 yards but the "Tim the Toolman" side of me says you can't have too much power. What do y'all think?
Once I get the scope in I'm sending the rifle & scope to get dipped in Mossy Oak Brush.
You just can't go wrong with a mauser action.
