Holosun 507 ProMax

Holosun 507 ProMax Competition Red Dot Sight

The Holosun 507 ProMax is a competition-focused open reflex red dot sight engineered around a large viewing window, multiple reticle configurations and fast, unobstructed sight acquisition. Its oversized window provides an expansive field of view while the Holosun Competition Reticle System (CRS) gives the user multiple reticle options to suit different preferences and shooting environments.

Available with Red, Green or Gold reticle options, the 507 ProMax combines a high-clarity aspheric glass lens with 1× magnification, unlimited eye relief and a parallax-free optical system. The optic also features 12 brightness settings, including two night vision compatible levels.

With an RMR-compatible footprint, side-loading CR1632 battery tray, Shake Awake technology and up to 50,000 hours of battery life in dot mode, the Holosun 507 ProMax combines competition-oriented visibility with practical everyday functionality.

Large Competition Window

At the centre of the Holosun 507 ProMax design is its oversized 1.10 × 0.87 inch viewing window. The large open-reflex format provides an expansive sight picture intended to support fast visual acquisition while reducing the amount of housing visible around the target area.

This competition-oriented window design is particularly useful where rapid sight acquisition and maintaining visual awareness around the aiming point are priorities.

Competition Reticle System – CRS

The 507 ProMax features Holosun's Competition Reticle System (CRS), providing multiple reticle configurations including dot and circle options. This allows the optic to be configured according to the user's preferred sight picture rather than being limited to a single fixed reticle.

The 507 ProMax is offered with Red, Green and Gold reticle options, providing additional choice based on personal visibility preferences and environmental conditions.

High-Clarity Aspheric Glass

The optic uses a high-clarity aspheric glass lens designed to minimise optical distortion across the large viewing window. Combined with 1× magnification, unlimited eye relief and a parallax-free design, the 507 ProMax provides a clear and natural sight picture through the open reflex window.

12 Brightness Settings & Night Vision Compatibility

The Holosun 507 ProMax provides 12 brightness settings, consisting of 10 daylight levels and 2 night vision compatible settings. This broad adjustment range allows reticle brightness to be configured for different ambient lighting conditions and compatible night vision applications.

Shake Awake Technology

Holosun's Shake Awake technology helps conserve battery power by allowing the optic to power down when it is not in use and reactivate when movement is detected.

Combined with an advertised battery life of up to 50,000 hours in dot mode, this reduces unnecessary battery consumption during periods of inactivity.

Side-Loading CR1632 Battery

The 507 ProMax is powered by a CR1632 battery housed in a side-mounted battery tray. This configuration allows the battery to be replaced without removing the optic from its mounting interface.

RMR-Compatible Footprint

The Holosun 507 ProMax uses an RMR-compatible footprint, providing compatibility with appropriately configured RMR-pattern mounting interfaces and plates.

Compatibility Note: always confirm the exact mounting interface, screw specification and plate compatibility for your application before installation.

1 MOA Adjustment

Windage and elevation adjustments are made in 1 MOA increments per click, with an adjustment range of approximately ±50 MOA for both windage and elevation.

Durable Aluminum Housing

The Holosun 507 ProMax is built around an aluminum housing designed for the demands of competition use. The optic carries an IPX7 waterproof rating and has a specified operating temperature range of -30°C to 60°C.
