Adler Arms Centurion BP-12 12 Gauge Bullpup Semi-Auto Shotgun, 19.75" Barrel, 3" Chamber
The Adler Arms Centurion BP-12 delivers a compact 29.5" overall length by moving the action behind the trigger, giving you a full 19.75" barrel in a maneuverable bullpup layout. A dual-piston gas system cycles everything from light target loads to heavy 3" shells, while AR-12 pattern magazines let you reload quickly and upgrade capacity as needed. Flip-up adjustable sights ride on a full Picatinny top rail, and the Mobil-style choke set (Full, Improved Cylinder, Modified) tailors patterns for any task.

What’s Included
- Original factory box
- Centurion BP-12 owner’s manual
- 1× 5-round detachable box magazine
The BP-12’s gas-operated, paddle-release action feeds from detachable magazines, giving you faster reloads than a traditional tube-fed shotgun. The steel magazine supplied holds 5 rounds, and the gun accepts higher-capacity AR-12 pattern mags and drums for greater versatility.
An aluminum receiver and ventilated aluminum handguard keep weight to a manageable 8.6 lb unloaded. The polymer frame and stock are finished in matte black and capped with a rubber recoil pad. A 15.0" length of pull fits most adult shooters, while the integral pistol grip delivers positive control.
Top and bottom Picatinny rails are ready for accessories, but the shotgun ships with flip-up polymer sights that adjust for windage and elevation. A cross-bolt safety sits above the trigger guard, and the familiar paddle-style magazine release speeds mag changes.
The 19.75" barrel is threaded for Mobil-style chokes and comes with Full, Improved Cylinder, and Modified tubes, allowing you to dial in patterns for home defense, competition, or field use. Chambered for both 2¾" and 3" shells, the dual-piston gas system lets you run light clay loads or heavy buckshot without adjustment.
