Im guessing its a Euro thing.(remember CZ isnt American made)<-- that would explain "why in the world" LOLWhy in the world is it not threaded 1/2x28? I bought one, it's my fault I didn't check further, but really?
Looks like I'm gonna sell it and have my current .22lr American cut off and threaded. Anybody see any reason not to do this.
I think DIP sells an adapter to convert it to 1/2X28
