The older genuine Brno's have a 16mm groove. I have a pair of 16mm CZ steel rings that I paid $120 for and never used; I'd sell them for $80.
If you want the best try these (formerly Hilver) in medium although probably out of your price bracket. Have used several pairs on my Brno's. The low is too low unless you have a small ocular (rear) eye piece on your scope to clear the bolt handle. Perfect for the Brno 581 auto though.
