The HiViz M400 M-Series Magnetic Front Sight Black | Green With Red Center Fiber Optic Front Sight gives vent-ribbed shotguns a crisp, bright aiming point without permanent modification. This snap-on magnetic sight uses HiViz’s LitePipe technology, combining a vivid green fiber optic rod with a contrasting red center dot to draw your eye naturally to the front of the rib for faster alignment and more confident shot placement in changing light.

Designed specifically for wide shotgun ribs, the M400 fits rib widths from 0.328" to 0.437" (21/64" to 7/16"), making it an easy upgrade for many Beretta, Browning, Mossberg, and Winchester models. Interchangeable green, red, and two-tone LitePipes let you tailor the sight picture to your eyes and environment, whether you are shooting clays, chasing upland birds, or working on fundamentals at the range. It’s a simple, tool-free enhancement that reflects HiViz’s focus on practical innovation for everyday shooters.
