It was my own demonstrator Tau Brno MK-300. I know its plain / simple design is not to everyone taste - but " you don't look and the mantle piece when stoking the fire". Everything is there to do the job.
People that have used it seem to like the way it shoots. I have not had problems reported with scope mounting on barrel, although I am trying a MTC Viper connect on it - that will mount on the actions 11mm rail and not use barrel mount.
