Description
The Holosun KPLT-FN509 adapter plate lets you mount a Holosun 407K or 507K micro red dot on an FN 509 optics-ready pistol. It creates a secure, properly aligned interface between the compact K-footprint optic and the FN 509 slide, so you can run a Holosun K-series sight on a platform that doesn’t natively accept it.
Machined from aircraft-grade aluminum with a protective hard-anodized finish, the plate keeps the optic low to the slide for a natural sight picture and snag-free carry, and is engineered to maintain zero under recoil. All installation hardware is included.
