The standard saddle is a bit small and the screw on the saddle marks your dovetail bar as it is the only part in contact with the dovetail bar.
This simple replacement/upgraded saddle from ADM increases the length of the saddle and grips using the whole surface area rather than just the screw head!

The upgrade takes less than 10 minutes to install, see my post on SGL for pictures of the steps needed:

If your scope was expensive then this upgrade is just for you!

This is a fantastic piece of kit and I would recommend that every AZGTi owner upgrades to this.

Very easy to fit, takes 5 minutes, and you only need a Phillips head screwdriver and an Imperial allen key.

The slowest part of the inmstallation is the careful removal of the plastic cap that covers the 4 screws holding the original saddle.
