ATA Arms NEO 12 Gauge Semi-Auto Shotgun

The ATA Arms NEO is an inertia-operated 12 gauge semi-automatic shotgun — a significant mechanical distinction from the gas-operated CY Synthetic in this collection. The inertia system uses the recoil energy of the fired shell to cycle the action rather than tapping propellant gases from the barrel, resulting in fewer moving parts, less internal fouling, and faster disassembly and cleaning. Shooters who value mechanical simplicity and low maintenance demands without sacrificing reliable semi-automatic cycling will find the inertia system the preferred approach.

The black alloy receiver provides a clean, modern aesthetic that contrasts effectively with the walnut stock and forend — giving the NEO a classic-yet-contemporary appearance that suits both field hunting and sporting clay use. CNC-machined for precision fit, the receiver is light enough to reduce carry fatigue while providing the structural rigidity required for sustained use with standard and magnum loads. The 3-inch chamber accepts both 2¾-inch and 3-inch factory loads without adjustment.

Five interchangeable choke tubes — Full, Improved Modified, Modified, Improved Cylinder, and Cylinder — are included, covering the full spread of hunting and sporting applications. The ventilated rib aids heat dissipation during sustained firing and provides a consistent sighting plane. The NEO sits between the entry-level CY Synthetic and the premium Italian brands in this collection, offering the inertia system advantage at an accessible price.
