XS Sights Big Dot Tritium Front Shotgun Sight – Optic Orange (Remington)

Description

The XS Big Dot Tritium is one of the fastest front sights you can put on a home-defense shotgun. That oversized dot demands your eye's attention and lines you up on target in a hurry, which is exactly what you want when the lights are low and time is short. The Optic Orange color reads with strong contrast in bright daylight, and the green tritium vial keeps you glowing when there's no light at all, so you've got a reference around the clock.

What Makes the Big Dot Tritium Different

The secret is XS's patent-pending Glow Dot paired with the tritium. The convex shape of the dot adds surface area, which means it soaks up more ambient light and charges the glow properties harder than a flat dot would. In daylight, orange gives you a crisp, high-contrast bead. As light fades, the color shifts toward yellow with a hint of red so it stays visible even before the tritium takes over, and once it's dark the green vial carries the load. It's a genuine improvement over a plain factory brass or steel bead, especially for aging eyes.

Fitment and Installation on Your Remington

This is the pedestal model (SG-2004-3N) with a stepped bottom made to sit over the factory front bead on Remington barrels that use a bead-on-pedestal setup. It works with a .125 to .140 inch diameter bead. Installation is straightforward: degrease the bead, fill the cavity on the underside of the sight with a two-part epoxy like JB Weld or Brownells Acraglas, set it over your existing bead, and clamp it until cured. The Big Dot itself measures 0.188 inches across, so it stands proud and easy to find.

Keep in mind this is a stand-alone front sight solution and isn't meant to pair with ghost ring rear setups. If your shotgun doesn't already wear a bead in that diameter range, you'll want to add a #6 or #26 front bead first. Backed by XS's 12-year tritium glow warranty, it's a simple, affordable way to make a defensive shotgun far quicker to point and shoot.
