The ATA Neo 12 Gauge Shotgun is an inertia-operated semi-automatic shotgun designed for performance and ease of use. Utilizes a simple inertia system with three main parts: the bolt body, inertia spring, and rotating bolt head, allowing for quick cycling and cleaner operation. The lightweight construction contributes to its balance and performance, making it one of the lightest semi-automatic shotguns available. It can accommodate both standard and extended shot shells, providing versatility for various shooting needs. The inertia system allows for easier cleaning compared to gas-operated shotguns, thanks to the absence of gas and residues.
