should probably just buy new, but in the meantime, if anyone is sitting on 19mm CZ550/BRNO ZKK mounts/rings with QD levers in Low or Medium, please let me know.

I'd consider: Warne (if pushed), Alaska Arms, Talley - 1" preferred, but 30mm if pushed. Gloss or Matt black only and in good condition.

max budget 45 (as decent Talley or Alaska Arms are around 75 imported).
