The dust cover is designed to be manually closed. Once bolt carrier assembly movement starts rearward or forward the milled out concave area of the bolt carrier pushes against the dust cover detent base and forces it open. The dust cover is spring loaded to push itself open and keep the dust cover out of the way during firing. If it were spring loaded to keep closed then there would be ejection port issues as the dust cover would be in the way and probably not able to open itself up under the speed of the firing cycle.
