Meprolight USA Tru-Dot Self-Illuminated Shotgun Sight Mossberg 500/590 Green Tritium Front

The Meprolight USA Tru-Dot Self-Illuminated Shotgun Sight brings combat-proven tritium aiming to defensive, duty, and hunting shotguns. This front bead sight is purpose-built for the Mossberg 500/590 platform and threads directly into the factory bead seat on a standard 5-40 thread, replacing the original bead with a self-luminous green tritium insert that glows continuously without batteries or ambient light.

Housed in a rugged steel body with a matte black finish, the Tru-Dot shotgun bead is engineered to absorb heavy recoil and rough handling while delivering a clean sight picture. The always-on tritium lamp produces a bright green glow that transitions instantly from day to night, allowing rapid instinctive aiming under low-light, dim interior, or after-dark conditions where a plain white bead simply disappears.

Designed as a dedicated night sight for shotguns where low-light aiming matters, the Tru-Dot bead draws on Meprolight's decades of combat-proven night-sight heritage, giving the shooter a clear aiming reference any time the shotgun is brought to the shoulder. Tritium technology means no switches, no batteries, and no ambient light required - the sight is always on, 24/7, for the life of the lamp.

Note: This listing is for the front bead only.
