I have the 452 American HB. Dumped it into a Boyd's Tacticool and prefer the ergo's,but that is subjective.

Like all CZ's it's gritty/schitty and sloppy. Broke the OEM rings in short order,but I'm hard on stuff. Was going to sell it with a 12X Leupold Target Scope and both handles for 700 clams,but decided I couldn't,mainly because I hate to sell anything.

With DIP 25MOA rail,it will reach the 800yd line easily,when wearing a 10x MQ Fixed [bleep] and that is a pretty good time.

The 455 option gets you the ability to drop-in a barrel yourself and that may be something that calls you.

Driving a Custom 77/22 Hummer now and prefer it,if for the rotary mag alone.

Bang for the buck,forget everything CZ and go Ruger American in Hummer,as you get the rotary mag and re-sprung their triggers blow ALL things CZ away.
