CROSSBOW Spider Additional Spacer and Screw (ADD ON FOR RAVIN- READ DESCRIPTION)

This spacer and screw will give your Crossbow post an extra inch of height. Some crossbow's including most Ravin's have a very short Picatinny rail on the bottom of the crossbow which means those users will need additional height in order for the post to easily slide into the receiver. 

Note: Another option would be to add a  Picatinny rail extender (sold separately on Amazon) to your existing rail and utilize your current Crossbow post with the standard 0-2 spacers that are included in your Crossbow Kit.
