XS SIGHT SYSTEMS Big Dot Tritium Yellow Night Sight for Bead on Plain Barrel Remington Shotgun (SG-2005-3Y)

The XS SIGHT SYSTEMS Big Dot Tritium Night Sight offers the best front sight visibility in all lighting conditions, combining tritium with XS' patent pending glow dot. Upgrade a home-defense shotgun to a high-contrast front sight that absorbs light and glows in less than ideal conditions. Optic Yellow is the best option for low light and has the brightest glow intensity. Primarily based on the white light spectrum, optic yellow is very reflective and will excite the photoluminescent properties of the dot faster than any other color. The increased surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot.

The sight require a .125 - .140" diameter bead. The kit comes with replacement bead for Mossberg shotguns. If current shotgun bead is not in that diameter range and is not a Mossberg, Brownells #6 or #26 front bead will need to be purchased and installed before XS Big Dot. Installs with any two-part epoxy, like JB Weld.
