Seamlessly integrate your favorite optic into the FN P90/PS90 using our low profile mounts. 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 up to 4.0oz (factory 1913 rail is 5.9oz, HBI mounts are 1.9-2.0oz depending on model). Our mounts DO NOT use the threaded holes on the left/right side of the receiver; all four of these holes remain open (two left side, two right side) for mounting lights/IR/1913 rails/switches/etc…

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).
