The vision holding mechanism is a highly robust and reliable folding mechanism.
The folder is designed to be used between the vision chassis mid section and vision chassis buttstock and will not fit any other accessories.
The folding mechanism is unlocked by the push of a button and locked by folding the buttstock back in position.
The way that the folder is designed makes the folder perfectly sturdy and the buttstock will not move freely unless moved by user, that being said, the folder is not hard for the user to move.
