The ATN Dovetail Helmet Mount is a professional-grade, precision-machined interface designed to securely attach ATN PS31 series night vision goggles to a standard helmet shroud. Utilizing the industry-standard dovetail interface, this mount offers a more stable and "slop-free" connection compared to traditional bayonet-style mounts, which is critical for maintaining optical alignment during high-movement activities. It features a versatile flip-up mechanism with an integrated auto-power-off function, automatically cutting power to the goggles when stowed to preserve battery life and prevent "green splash" on the helmet. With multiple adjustment points for vertical height, tilt, and fore/aft eye relief, it allows users to customize the position of their dual-tube system for a perfect, ergonomic fit.
