The XS Sights SHOTRAIL provides a versatile platform for a variety of sighting solutions. The set consists of an anodized aluminum rear Picatinny rail, an adjustable ghost ring sight, and a front tritium dot sight. The rail is compatible with Weaver or Picatinny mounts, allowing the shooter to add their desired red dot or optic. The low profile ghost ring has a tough steel aperture, making an ideal backup sight. XS banded front sight allows the shooter to add a front sight without extensive gunsmithing work. It has adjustable elevation blade to account for variation between shotguns and ammunition. It is ideal way to upgrade to rifle sights without having to solder on a ramp and refinish the barrel. The band fits only barrels with diameter 0.840" - 0.875" (it does not fit on heavy barrels). The standard dot tritium at the top of the elevation blade provides high visibility in all lighting conditions
