Holosun 509 Adapter — Picatinny Low Rail Mount

Holosun 509 Adapter for Picatinny Low — an adapter/mount that converts a Holosun 509 optic interface to a Picatinny low rail. It provides a secure low-profile mounting option for optics designed for the 509 footprint.

This adapter is intended to allow installation of a Holosun 509-series optic onto firearms or platforms equipped with a Picatinny low rail. The mount is focused on providing a stable, corrosion-resistant interface between the optic and Picatinny rail while minimizing added height.

The adapter addresses the need to place a 509-pattern sight on a Picatinny-equipped slide or rail interface without fabricating custom parts. It is suitable for range, duty, or other applications where a low-profile Picatinny mounting solution is required. The design emphasizes secure attachment and resistance to recoil-related loosening.

• CNC-machined from 6061 aircraft-grade aluminum for structural rigidity.
• Type III hard-anodized matte black finish for surface durability and corrosion resistance.
• Stainless steel Torx-head M3 screws for secure, wobble-free attachment.
• Low-profile design that minimizes optic height above the Picatinny rail.
• Engineered specifically for Holosun 509-pattern optics to interface with Picatinny low rails.
• Corrosion-resistant construction suitable for regular use in field or range environments.
• Limited lifetime warranty against manufacturing defects (manufacturer-provided warranty).
