DOGTAG also reduces the amount of space between the optic and the slide securing the optic to prevent any movement and removing the possibility of the red dot shifting off zero. Finally the deflection table also doubles as an action point in the event of single hand operation (say in the event of an injury) the table can be used to perform the action versus the optic and preventing damage to the optic.
