CZ 805 Bren S1 Carbine 5.56 NATO 16.2-Inch FDE Semi-Automatic Rifle
The CZ 805 Bren S1 Carbine brings the proven Czech military Bren platform to the U.S. market in a civilian-legal, semi-automatic configuration. Chambered in 5.56mm NATO with a cold-hammer-forged 16.2-inch barrel and fully finished in durable FDE Cerakote, this rifle pairs modern modularity with battlefield-tested reliability.

The 805 Bren S1 uses a 7075-T6 aluminum monolithic upper receiver with a full-length numbered Picatinny rail, giving ample space for optics while maintaining rigidity. Six Torx screws secure the barrel, allowing quick caliber changes and easy maintenance.
A three-position adjustable gas valve lets the shooter fine-tune performance for standard, adverse, or suppressed use. The reversible, non-reciprocating charging handle doubles as a forward assist, adding flexibility for left- or right-handed operation.
The modular magwell ships set up for STANAG magazines and can be swapped for proprietary or AK-pattern inserts, making the rifle adaptable to different magazine preferences. An ambidextrous safety selector and magazine release further simplify operation for any shooter.
The folding, four-position telescopic stock with adjustable cheek rest allows the rifle to be fired while folded and provides a 13.5-inch length of pull. Combined with the FDE alloy handguard and factory muzzle brake on the 1/2-28 threaded barrel, the carbine is ready for accessories and recoil control right out of the box.
