Faced with the exact same problem with my BRNO #2, I stumbled onto a guy in Czech Republic who deals in BRNO .22 stuff who had rings. I found him on Gunbroker, maybe 2-3 years ago now and he fixed me right up. I just now went into my GB account to see if I could call up my buying history and I'm darned if I can figure it out. If someone knows how and tells me maybe I can find the guy's contact info.
