FB Radom, Fabryka Broni Łucznik in Radom, is the Polish state arms maker best known for its VIS pistols and military rifles. Its MPS, a modular striker fired 9x19 pistol with a polymer frame, was unveiled in 2023, and its slide comes cut for a red dot as standard. Our FB range is built around that cut.
What a plate does
An optics cut is only a pocket in the slide with a cover on top. To mount a red dot you need a plate that fits the pocket on one side and the base of your optic on the other. A good plate holds the optic low in the slide and without play or tilt, so the dot returns to the same point after every shot and keeps its zero.
Two plates by 2BME
We carry two MPS plates made by 2BME from aircraft grade aluminium. One takes optics built to the Trijicon RMR footprint, the other the Shield RMSc footprint. Between them they cover a large share of pistol red dots, because many makers build their optics to one of these two patterns.
RMR or RMSc?
The RMR footprint is found on full size pistol optics, often with a larger window. The RMSc footprint is smaller and is used on slim optics for compact pistols, including many Holosun and Shield models. Look at the screw pattern under your optic or at its specification, then choose the plate with the same name. The brand of the optic does not matter; the pattern does.
Fitting
Take off the factory cover, seat the 2BME plate in the pocket and tighten its screws before the optic goes on top. Use thread locker as the optic maker recommends, and check the zero after the first few magazines.
Both plates are in Optics ready plates for FB, and the Accessories for FB MPS page lists everything for the pistol.
Frequently asked questions
Does the RMR plate only take Trijicon optics?
No. Any optic built to the RMR footprint fits, whatever the maker.
