Hi. New to rimfire both shooting and forum. I have a 10/22 i bought just to have some fun shooting in the backyard. That led me to a potential rabbit hole. I stopped before I started to pull the proverbial trigger on parts for that rifle. In my search for possible 10/22 left handed parts I found CZ457 left handed rifles. I have been looking and reading all about CZ 457. But there is not a lot that compare the CZ left handed models. So I am looking for input from the highly intelligent left brain dominant shooters. What model did you choose and why? And did it work out for you? Now for what I plan to do is to use a heavy barrel with a silencer. I will be using it for target/ranger and plinking at home. I have no plans to shoot competitive or to hunt with it. I am think of the CZ 457 VARMINT LH. But I no it is not threaded. So I would have to do that. The CZ 457 P. I woudREMIUM LH is threaded but no heavy barrel. And finally the CZ 457 AMERICAN LH. I would prefer to have a 16~20". I am on the fence about replacing the stock. Only would if I enjoy it more than my other range rifles. Budget is around $2500 for gun, suppressor, and scope. thanks for the forum and it's great members.
