I have an older 2004-05 Airgun Express Catalog (My best reference) that does not show an Stutzen in .22cal. I'm not sure any of the .22cal M-46's were imported to the US. I must say that the .177 pictured is a beautiful rifle, one for the short list of any collector. My only complaints with my m46 was the front sight and plastic so-so trigger.
I didn't know if they had any here in US or not ? I do know that RWS / Umerex who ever did make it in .22 and a .22 Stutzen . Oh well , I am also looking to maybe get a RWS 48 or the Chinese or Spanish clone ??
I have a RWS 34 in .177 that I am going to part with and use the funds towards whatever I find .
