Eternal BP-12 12 Gauge Bullpup Semi-Auto Shotgun

The Eternal BP-12 is a 12 gauge semi-automatic shotgun built in a bullpup configuration — a layout that places the action and magazine behind the trigger group, allowing a full-length barrel within a significantly shorter overall package than a conventional stock design. Manufactured by Eternal Arms in Turkey, the BP-12 is the only bullpup shotgun in this collection and the most affordable shotgun overall, combining a tactically modern format with the lowest price in the range.

The bullpup layout's core advantage is the length-to-barrel ratio: where a conventional semi-auto with an 18-inch barrel has an overall length of approximately 38 inches including the stock, the BP-12's bullpup design achieves a similar barrel length in an overall package closer to 28 inches — a reduction that meaningfully improves maneuverability in confined spaces, vehicles, or tight terrain without sacrificing the ballistic performance that comes with a full-length barrel.

Integrated Picatinny accessory rails are fitted on the top of the receiver and along the forend, allowing direct mounting of red-dot sights, scopes, tactical lights, and other accessories — making the BP-12 the only optics-ready shotgun in this collection outside of the Eternal BP-12 itself. A threaded muzzle accepts compatible muzzle devices for recoil management or accessory attachment. For buyers who specifically want a compact, tactical-format semi-automatic shotgun with optics capability at the most accessible price in the collection, the Eternal BP-12 is a uniquely configured and aggressively priced option.
