Optics ready plates for FB

The FB MPS (Fabryka Broni Modular Pistol System) is a Polish service pistol with an optics-ready cut on the slide. Plates bridge the factory recess to standard red dot footprints, allowing direct mounting without modification to the slide itself.

The reason to mount an optic on the FB is speed and consistency — a slide-level dot is faster to acquire than irons and stays in your sight picture as the gun cycles. The plate is the bridge: it mates the gun's mounting interface to your red dot's footprint and holds the optic low and rigid so point of aim does not wander.

Compatibility is set by the FB's mounting cut on one side and your optic's footprint on the other — both have to match the plate. Where a co-witness iron matters, look for a plate with an integrated rear sight. Always confirm the exact fit on the individual product page before ordering.
