Offered in seven variants, each compatible with a different popular mounting footprint (Aimpoint Acro, Aimpoint Micro, Holosun AEMS, Holosun SCRS, Primary Arms SLx, Trijicon MRO, Trijicon RMR), once installed, the FN P90/PS90 Low Profile Optic Mount from HB Industries replaces the Belgian carbine’s top-mounted M1913 Picatinny rail.
Not only does this considerably reduce the associated optic’s height over the bore—providing a more ergonomic cheek weld—but, in the case of the Trijicon MRO version (shown), it also cuts the weight of the PS90 by more than 4 ozs.
Each mount is machined in the U.S. from billet 6061-T6 aluminum that is then hardcoat-anodized, and the installation process is reversible.
MSRP is $104. For more information, visit hbindustries.net.
