Happen to do some minor stock work on a gents CZ527 varmit .223 recently. For some reason its factory lenght of pull is 13 1/4" and its 6'2" owner had a problem with it. I added a 5/8" spacer to stock. Anyway, really nice trigger on the rifle and its quite accurate. You'd like the feature of pushing forward on trigger to set it for a 2 oz. or so trigger pull. Twist is 1/9", so it can handle up to 70 gr bullets. Rifle owner likes it so much he intends on getting another in .221 fireball. Unfortunately, rifle costs over $700.
Personally, I'd take a look at the Marlin X .223 Varmit heavy barrel recently introduced. Have the .308 version of it and am quite happy with it. Hardly a CZ527, but for 1/2 its price, it should be an accurate rifle with a decent trigger. As mentioned earlier, more money to spend for a decent scope.
