The XS ShotRail with Ghost Ring Rear and Tritium Front Sight is a complete rail-and-sight package for the Mossberg 500, 590 and 930 shotguns (XS part no. MB-4001R-4). The anodized aluminum rail mounts to the receiver and carries a precision-machined ghost ring rear sight with elevation and windage adjustment, while a tritium front sight on the barrel gives a sight picture that works in low light. The rail accepts Weaver or Picatinny rings, so it can also serve as an optic mount. The kit includes its own hardware, from the apertures to the threadlocker.
