Holosun Lower 1/3 Co-Witness QD Mount

Holosun Lower 1/3 Co-Witness QD Mount

This is a purpose-built mounting solution for Holosun 503 and 403 series red dot sights. The quick-detach lever allows rapid attachment and removal from standard Picatinny rails without tools—a genuine advantage in dynamic shooting situations.

Key Features

• Quick-Detach Lever: Enables fast optic mounting and removal
• Lower 1/3 Co-Witness Height: Positions your red dot to align with iron sights for redundancy and enhanced accuracy
• Durable Construction: 6061 T6 aluminum with hard-anodized finish resists corrosion and impacts
• Complete Package: Includes spacer, four installation screws, and Allen wrench

Design and Function

The mount's lower 1/3 height is a practical choice. Your iron sights remain visible through the optic window, giving you a backup aiming system if the red dot fails. This redundancy is valued by serious shooters who demand reliability.

The hard-anodized aluminum finish provides genuine corrosion resistance—important whether you're shooting in humid conditions or storing the rifle long-term. The engineering is straightforward and proven: no unnecessary complexity, just solid functionality.

Ideal For

Tactical training, competitive shooting, hunting, and any application where you want quick optic changes and iron sight backup.
