I threaded my Marlin 30AS 30-30, but not my dad's Golden 39A Mountie .22lr due to the magazine tube being too far down the barrel. There might be a way to modify it, but I don't want to ruin it. I'm sure there are other lever action .22s that would work fine for threading. I love shooting my 30-30 suppressed so if you want a suppressed lever rimfire, I say go for it.
