Our Assessment: The CZ 805 BREN S1 Carbine is the civilian semi-automatic variant of the Czech military’s modular battle rifle platform, designed to serve as a modern, adaptable, and robust alternative to traditional 5.56 NATO rifles. Chambered in 5.56x45mm and built around a short-stroke gas piston system, the BREN S1 is known for its reliability in harsh conditions, modularity, and ergonomic enhancements over the AR-15 platform. This version features full ambidextrous controls—including the safety selector, magazine release, bolt catch, and a reversible reciprocating charging handle—making it ideal for both right- and left-handed shooters. This example, manufactured in 2017, is finished in factory Flat Dark Earth and retains about 98% of its original finish, showing only light signs of use. It features a 16.2” cold hammer-forged barrel with a three-prong flash hider, bringing the overall muzzle length to 18.5”. The monolithic upper has a 16” uninterrupted Picatinny rail and includes factory flip-up iron sights. The rifle’s furniture includes a collapsible, side-folding stock with a two-position cheek riser, a CZ Scorpion-style pistol grip, and a 7” M-LOK handguard—providing both excellent ergonomics and modern accessory compatibility.

This BREN S1 includes one 30-round D&H magazine and remains in excellent overall condition, with a sharp bore, tight mechanics, and rugged battlefield styling. Whether you’re a modern rifle enthusiast, collector of Eastern European small arms, or a shooter looking for a proven piston-driven alternative to the AR platform, the CZ 805 BREN S1 offers a rare blend of military pedigree, user-centric design, and standout aesthetics. It’s a highly capable and distinctive rifle ready for the range or collection. -R.E.
