Standard Manufacturing DP-12 Gen II | 12 Gauge | 18.8″

The Standard Manufacturing DP-12 Gen II is a double-barrel, pump-action 12 gauge shotgun designed around a twin-tube magazine concept to deliver two shots per pump through a single trigger. The design combines an aluminum receiver and polymer components with a synthetic stock and co-molded non-slip pistol grip for repeated handling and control. Key mechanical features include inline feeding, ambidextrous safety and slide release, and included Tru-Choke spreader tubes for patterning.

Typical uses include range training and practical shotgun competition where follow-up shots and magazine capacity are primary considerations. The DP-12 is also used in professional training scenarios requiring repeated, rapid follow-up shots during drills.
