Description

The Holosun HSCQD1 is a two-piece quick-detach mount for Holosun 403 and 503 series micro red dot sights. It clamps to any standard Picatinny or Weaver rail and, with the included spacer, sets the optic at a lower 1/3 co-witness height so AR-height backup iron sights appear in the lower third of the window.

Machined from 6061 T6 aluminum with a hard-anodized finish, the HSCQD1 uses a quick-detach lever for fast installation and removal with reliable return-to-zero, positioning the optic 1.63″ from the rail to the center of the lens. Four installation screws and an Allen wrench are included.
