Ever since the Scorpion EVO 3 S1 semi-automatic carbine was launched as a civilian-grade version of the new-generation sub-machine gun bearing (almost) the same name, shooters from all around the world expected CZ - Česká Zbrojovka A.S. − the biggest firearms manufacturer in Czech Republic, and one of the world's major players in the field − to fulfill the promise made in the previous months and to complete the new modern sporting guns line with another highly awaited model.

Now, well over one year later, the promise has been fulfilled and the dream is reality: CZ launched the .223 Remington caliber CZ-805 BREN S1 semi-automatic modern sporting rifle.

Engineered by Jiří Kafka at the Uherský Brod plant, the CZ-805 BREN S1 is a civilian-grade, commercial version of the CZ-805 BREN A1 / BREN A2 weapon system, conceived to provide a modern, modular alternative to military and Police operators worldwide and to replace the aging SA Vz.58 7.62x39mm assault rifle thatis still the mainstay of the Czech Armed Forces.

Jiří Kafka is one of CZ's most important engineers, and one of the creators of the CZ-805 BREN assault rifle system; the CZ-805 BREN S1 assault rifle is thus guaranteed to remain faithful to the principles of modularity and ruggedness that inspired the original design.
