Standard Manufacturing SP12 Ambidextrous Pump Shotgun 12 Gauge 18.5″ Barrel 7-Round Black

The Standard Manufacturing SP12 Pump Shotgun redefines what a compact home-defense shotgun can be. Engineered as the only truly ambidextrous pump-action shotgun on the market, the SP12 places every control within equal reach from either side, making it an ideal platform for left- and right-handed shooters alike. Its bottom-ejecting, bottom-feeding design keeps spent hulls and incoming rounds out of your line of sight, delivering a cleaner, faster shooting experience under pressure.

Built for serious use, the SP12 features a receiver machined from a billet of aircraft-grade 7075 aluminum — one of the strongest aluminum alloys available — keeping the package lightweight without sacrificing durability. A full-length M-LOK mounting system runs the length of the handguard, giving you virtually unlimited options for lights, lasers, foregrips, and other tactical accessories. The threaded 18.5″ barrel is designed to accept standard choke tubes and muzzle devices, adding versatility for a wide range of applications.

Chambered for 3″ 12-gauge shells, the SP12 accepts 1¾”, 2¾”, and 3″ ammunition, so you’re never limited in your load selection whether you’re stocking birdshot, buckshot, or slugs for home protection. AR-style ambidextrous controls make manipulating the safety instinctive, especially for shooters already familiar with the AR platform.
