The Post Family helps the Lock Family hold everything together. The Round Post M-Lok(RPM) and the Round Post M-Lok Mini are both M-lok compatible and typically used to attach rifles. The Quick Detach Post attaches with a flush cup hole, is toolless, and is used in applications from cameras and rear bags to rifles and tripods. While the Anywhere Post gets its name from the places it can be used. The Anywhere Post needs only a tiny hole in a strap or a 10-32 threaded hole to find a home.
