The sliding rail accessory mount is designed to mount our accessories to our patented rail system. The sliding rail accessory mount is a double dovetail design. The first dovetail mates with the rail and runs horizontal to the mount. The second dovetail runs vertical on the mount this allows our accessories to be slid on and off easily. This mount works when our rail system is mounted on a vertical plain. The accessory rail mount must be slid on the rail from one end of the rail. The sliding rail accessory mount is made from black UHMW (& Starboard) UHMW is a very tough industrial plastic with Teflon type properties and measures approximately 3” long by 1.125” thick and 1.780 wide.
