The 41PX has launched the Arctic No. 1 as the successor to the Antarctic series, priced at ¥54,800 including tax. This model features a 6.5-inch M-LOK handguard and a lightened receiver, resulting in a total weight of 2.0kg. Despite its lightweight profile, the full-metal construction maintains structural rigidity. The exterior is finished in Tactical Gray and includes a custom side plate designed by Osumi, which depicts a polar bear and the North Star.

Internally, the Arctic No. 1 is equipped with a brushless motor, pre-cocking electronic circuitry, and 12:1 high-speed gears for rapid response. It also incorporates the Lancer Tactical New Chamber to manage flight trajectory. Each unit is assembled in Akihabara, Japan, by 41PX mechanics who select and install both the internal and external components. This limited-production model is designed for immediate use without additional configuration.
