Seamlessly integrate any optic using the Trijcon® RMR/SRO footprint into the FN P90/PS90 using our low profile mount. Our optic mounts are designed to reduce the height over bore issues typically associated with the P90/PS90, provide a more natural/comfortable cheekweld, and reduce the weight of the gun by 3.9oz (factory 1913 rail is 5.9oz, HBI RMR mount is 1.98oz).

All of our P90/PS90 optic mounts are optimized using computer analysis (FEA) and tested using multi directional high impact loading. They are suitable for hard/professional use. Our mount utilizes the factory threaded holes in the receiver and is a drop in/direct fit part. Machined from billet 6061T6 aluminum and hard coat anodized to MIL-A-8625. Mounting hardware has been standardized to use a 3mm hex driver (all FN and HBI screws on P90/PS90 are 3mm drive, single tool).

This mount is compatible with the following optics:

Trijicon® – RMR, SRO
Holosun® – HS407, HE407, HS507, HE507, & HE508 Series (HE507K requires additional plate)
