Gforce Arms GFONE1228B One 12 Gauge Semi-Auto 3" 3+1 28", Black, Synthetic Furniture, HiViz Fiber Optic Sight, Oversized Controls, 5 Ext. Chokes, Includes 10rd Mag Tube Ext.

The Gforce Arms GFONE1228B One 12 Gauge Semi-Auto shotgun delivers reliable inertia-driven performance across a broad spectrum of 12-gauge ammunition, from full-power 3-inch magnum loads to reduced-recoil 1-ounce field rounds. Built on the proven GForce One operating system, this 28-inch barreled platform combines tactical ergonomics with the versatility demanded by operators working patrol, training, and sport shooting environments where ammunition flexibility is non-negotiable.

The shotgun features a 3+1 capacity with an included 10-round magazine tube extension, expanding loadout potential for extended engagements or training scenarios. HiViz fiber optic sighting provides rapid target acquisition in variable light conditions, while oversized controls—including safety and charging handle—function reliably with gloved hands and minimize fumbling under stress. The synthetic black furniture resists corrosion and saltwater degradation, critical for operators deployed in harsh coastal or maritime environments. The barrel ships with five interchangeable choke tubes, enabling users to optimize shot patterns for specific distances and mission profiles without requiring multiple shotguns.

This platform suits tactical teams, law enforcement training units, and sport shooters who demand ammunition interchangeability and the ergonomic advantages of semi-automatic cycling. The 28-inch barrel balances velocity development and handling; the extended 10-round tube supports high-round-count training drills and competition formats where reload cycles directly impact stage times. At 9.6 pounds, the GFONE1228B maintains manageable recoil impulse and mounting stability for bench work or supported shooting positions.
