Made from 1964 (if I recall correctly) until the nineties. Construction and assembly/disassembly details in Bolt Action Rifles by Frank de Haas. ZKK rifles use the same replaceable foresights as the ZG47/CZ550 rifles which are available in various heights. Aftermarket foresights are also available from at least one European manufacturer. The rifle should come with a single stage trigger and a straight-blade single-set trigger. ZKK rifles came with a plainer stock (decorative schnabel and no cheekpiece) such as on my ZG47 and a triangular fore-end California-style stock with cheekpiece and whiteline spacers (and who knows what else, given that we are talking about the Brno brand?).
I have found Warne QD rings to be fully reliable vis-a-vis scope security and zero-maintenance when detached from and reattached to the rifle. If you rifle has the peep sight be careful not to lose the actual peep. The only good reasons for removing it are:
1. To remove water after soaking the rifle in a stream; and
2. To secure the clamping screw with a nut-locking compound.
Welcome to Brno/CZitis (a totally irretrievable situation) and have fun!
