Springer Precision Docter/Burris Dovetail Mount
This is a one piece aluminum sight base for the XD/XDm/Glock pistol. It uses the rear dovetail to mount the sight to your slide. Hard anodized for a long service life, we also added polymer tipped set screws fore and aft to our mount to make the sight mount much more stable than other designs.
This will not work on the 5.25 models with the factory adjustable rear sight
