Description
The Holosun 509PLT-FN509T adapter plate lets you mount a Holosun 509 or 509T enclosed red dot on an FN 509 optics-ready pistol. It creates a secure, properly aligned interface between the 509 footprint optic and the FN 509 slide, so you can run a Holosun enclosed sight on the FN 509 platform.
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.
