The Holosun 509 adapter plate for the HS507C footprint (part no. 509PLT-507C) lets a shooter mount a Holosun 509 optic to a slide already cut for the 507C pattern, extending optic compatibility without a new mill job. Holosun CNC machines the adapter from 6061 aircraft aluminum with a Type III hard anodized finish, built to withstand hard-hitting recoil and rough tactical use. Among footprint-conversion red dot mounts, this 509 adapter favors shooters upgrading from a 507C to a 509 optic.
