Two things I THINK I remember: First, BRNO and CZ are the same company. Brno was the name of the town in the Former Czechoslovkia, and I guess since there's now the Czech Republick and Slovakia, they dropped the Brno name. I'm not sure of this, but have a Brno Fox .22 Hornet which fits into a CZ stock perfectly. And the rifles I have, the Brno .22 Hornet and a CZ .223 are practically identical.
Second is I THINK I read a review of the single shot rifle shown this year, or maybe last year. I don't remember it being a CZ rifle, think it was from Turkey. But I may be wrong. As I remember, the accuracy wasn't good and the wood was problematical. So I'd look before I buy.
Third is the hogback stock. I like it! Got one on my CZ 6.5 x 55 and it's purty.
