4UAD SmartAirsoft

4UAD SmartAirsoft is a Taichung, Taiwan team that began as an airsoft testing lab and YouTube channel, running measured experiments on hop-ups, buckings and other parts and publishing the data. It also offers custom test fixtures, product filming and grading for other companies. Out of that testing work came its own parts line, sold under the 4UANTUM Industries name. The range covers Magnus Pro precision hop up chambers for VFC HK416, GHK and VFC AR gas rifles, the APFG MCX and Hi-Capa or 1911 pistols, Friction Pro buckings for AEGs and gas blowback guns, and a flat custom trigger for Glock-pattern pistols. There is also a set of pen-tip workshop fluids: a grease lubricant, a gear lubricant, an axle oil, an airtight sealant and two thread lockers, plus the Fogg-Off anti-fog spray. Players buy these through airsoft shops that stock the brand, or direct from 4UAD's own web store, which also sells patches, keychains and stickers and takes wholesale and collaboration enquiries.
