Read on DJI USA's product page on 2026-10-19: "Osmo Dual-Direction Quick-Release Adapter Mount", compatibility "Osmo Action 6" and "Osmo Nano", 44.4 x 18.2 x 29 mm, 16 g, one in the box, and the page showed it out of stock that day. DJI's compatibility list ticks it for the Action 6 and crosses it for the Action 5 Pro. The Action 6 manual lists it in both combos and says its clips go into the camera's quick-release slots and are fixed with the locking screws. A maker-only part: the link is not tagged and earns nothing.
