The micro-adjust top was designed to fulfill two needs.  First, to provide shooters with a sand filled top with small hard bags and second, provide shooters with a single top for easy adjustment for different width stocks and pressure on the sides.  With this top shooters can shoot a sporter stock then change to a 3" wide stock in a matter of seconds while also setting the amount of side tension on the stock.  Most shooters has two tops: one set-up for the sporter and one for the heavy gun.  This top allows for both and all combinations in between.  The top also has the same tried and true windage adjustment built-in.  Most any rest configuration can be accommodated.
