The Hi-Viz M-Series Magnetic Front Sight (brand part no. M200) is an ultra-narrow snap-on shotgun sight built around the same two-tone LitePipe fiber optic system as the rest of the M-Series line, in green with a red center dot. This ultra-narrow-base version is sized for tighter vent ribs, fitting from 0.171 to 0.265 inch (4.2mm to 6.7mm), so it covers shotguns whose ribs are too slim for the standard M-Series bases. The magnetic mount clamps straight over the factory bead with no drilling or gunsmithing, and comes off just as easily if you switch it to another gun. Clays and upland shooters running a narrow-rib shotgun get the same bright, two-color fiber optic sight picture as wider-rib guns.
