Built on a bullpup platform, the BP-12 Centurion provides a short overall length of approximately 29.5 inches while maintaining a 20 inch nominal barrel for effective patterning and velocity. It is gas-operated and semi-automatic, chambered for both 2-3/4 and 3 inch 12 gauge shells, and uses a detachable box magazine to achieve a 5+1 capacity.
The receiver is aluminum with a black finish, paired with a durable black polymer frame and stock. A rubber recoil pad and a 15.0 inch length of pull support comfortable handling and control. The shotgun features right-side ejection and a cross-bolt safety.
A vented aluminum handguard with diagonal slots surrounds the barrel, and a full-length top Picatinny rail runs the length of the action. Additional short rail segments are positioned at 3 and 6 o'clock. Flip-up front and rear sights are installed. The charging handle is on the right side with a checkered knob for positive purchase.
The barrel is threaded for screw-in chokes and uses the Mobil-pattern interchangeable choke system. Three chokes are included — Cylinder, Modified, and Full — with a choke wrench for quick changes. Markings include CAI Georgia, VT import stamp and "Adler Arms Made in Turkey," reflecting Turkish manufacture and import by Century Arms International.
