FAQ

Which optics fit this plate?
It’s designed specifically for the Holosun 509 ACSS Primary Arms edition, not other Holosun or Trijicon models.

Does this adapter plate include a rear sight?
Yes. It comes with a steel dovetail rear sight so you maintain backup aiming capability.

Is steel better than aluminum for an optic plate?

Do I need a gunsmith to install it?
