The XS Sights SG20033 Big Dot Tritium Front Sight is a shotgun sight upgrade designed to cut through dim light and fast-moving scenarios where target acquisition matters. This tritium front sight mounts over your existing bead, pairing a self-illuminating dot with a bold white ring that anchors your eye and speeds focus when seconds count. Whether you're hunting low-light conditions or running your shotgun on the range, the high-visibility design bridges the gap between instinctive shooting and precise aiming.
Installation is straightforward: the sight epoxies directly over factory front beads ranging from .125" to .140" in diameter using Brownells Acraglas Gel, then hardens in place. If your shotgun bead sits outside that range, you can swap it with a standard Brownells replacement (sizes #6 or #26, depending on your barrel threads). The plain barrel model features a cupped bottom designed to seat securely on round shotgun barrels. Machined from steel with a matte black finish, the Big Dot itself measures .161" (4mm) across—large enough to pick up fast in low light but small enough to maintain usable precision at reasonable shotgun distances.
XS Sights tritium sights are built for hunters and shooters who need dependable sight acquisition when ambient light fades. The green/white tritium combination delivers contrast that works in dawn woods, evening marshes, or indoor shooting situations without batteries or external activation. This is a no-fuss upgrade that bolts onto the sight picture you already know.
| Brand | XS Sights |
| Model | SG20033 |
| Sight Type | Shotgun front sight, tritium with white ring |
| Material | Machined steel |
| Finish | Matte black |
| Dot Diameter | .161" (4mm) |
| Tritium Color | Green/White |
| Bead Diameter Compatibility | .125" to .140" (3.2mm to 3.5mm) |

| Installation Method | Epoxy (Brownells Acraglas Gel) |
The SG20033 is designed for Remington shotguns with round barrels and front beads in the .125" to .140" diameter range. If your bead sits outside that tolerance, you can replace it with a standard Brownells bead (size #6 for 3-56 threads or #26 for 6-48 threads). Some barrels may require drilling and tapping to accommodate the #26 bead; check your barrel specs or contact a gunsmith if needed.
Yes. Tritium is self-illuminating and requires no batteries, switches, or power source. It glows continuously and will remain visible in low-light conditions, though brightness will gradually diminish over a 10–12 year lifespan.
The SG20033 installs using Brownells Acraglas Gel epoxy. You fill the cavity on the underside of the sight, press it over your front bead, and allow it to cure fully. Acraglas Gel is sold separately.
The plain barrel model is designed for round shotgun barrels. If your shotgun has a vent-rib or other barrel profile, verify compatibility before ordering or contact XS Sights for alternate models that may suit your setup.
