The BRNO ZKK 600 is a bolt action sporting rifle manufactured by Zbrojovka Brno in Czechoslovakia, built on a Mauser-type controlled round feed action with a full length claw extractor, fixed blade ejector, and dual opposing locking lugs. The ZKK 600 is the medium length action variant of the ZKK series, sized for standard length cartridges such as .270 Winchester, 7x57mm Mauser, and .30-06 Springfield, slotting between the shorter ZKK 601 and the magnum length ZKK 602. The action incorporates a single set trigger mechanism, engaged by pushing the trigger forward to achieve a lighter pull for precision shooting. The rifle feeds from an internal box magazine with a hinged floorplate released by a catch inside the trigger guard.

This example is chambered in .270 Winchester, serial number 79056, and is marked as manufactured by BRNO of Czechoslovakia. The barrel is threaded at the muzzle and fitted with a thread protector. The walnut stock features checkered grip and forend areas. No original box or accessories included.
