brno 600

Has anyone else ever experienced that after closing the bolt on a Brno Zkk-602 (or a 600), the trigger gets stuck and is impossible to pull (i.e the firning pin doesn’t release and the cartridge therefore can’t be fired)? I experienced this today in my 602 which is a 450 Rigby, re-chambered...

Hello there purchased the rifle and i really like to know theres anywhere a 3 position safety available and im searching for another trigger like a timney. Unfortunately ive never seen them anywhere Sorry for my bad english, im from switzerland :-) Greetings
