Low-profile aluminum mount uses the factory rear sight dovetail to mount a Burris FastFire or Docter red dot sight on the slide of your Springfield XD/XDM pistol.  Easy-to-install, no gunsmithing required. Simply insert into the dovetail and tighten the two steel Allen head screws, front and rear, for a secure hold. Polymer-tipped Allen won’t mar the slide finish and help create a stable, balanced sight platform. Mount is contoured for a perfect fit to the sight body, also using two Allen head screws. One piece machined aluminum construction, hardcoat anodized for additional strength and long service life.
