Doc , I recently purchased a CZ 452 American in left hand 22lr And I can say that I am very pleased with the rifle. The trigger is not great but usable , I have ordered a yodave kit to fix the trigger (lighter springs and shims ). I literally unboxed the rifle , slapped a 39$ scope I had laying around and started shooting 1/2" groups @ 50 yds .
I realize that is not out standing but considering the scope is focused for 150 yds. and the trigger could be better I am pleased . After the half hour range session I herd squirrels on the back 40 and away I went.
