MPB is a special fiber optic front sight attached directly to the barrel of a shotgun, which does not have a sight rail (pump, automat). This is a very popular and useful pushup fiber front sight used in IPSC competitions (e.g. Mossberg).
The manufacturer is the American company HI-VIZ - a global leader specializing in the production of fiber optic sights. HI-VIZ optical fibers are characterized by excellent absorption of even negligible amounts of light, especially in conditions of difficult visibility (gray, foggy or cloudy days). HI-VIZ instruments are factory assembled by many weapon manufacturers and have been used successfully by hunters and sport shooters around the world for many years.
HI-VIZ fiber optic front sights , thanks to their clarity, facilitate the correct composition and
accelerate accurate firing of the shot, which is why they are great help during sport shooting and hunting.
