Holosun® HS507 PROMAX RD PRS Open Pistol Reflex Sight

The Holosun HS507 PROMAX RD PRS is an open pistol reflex sight with an enlarged competition window and a red Performance Reticle System. The PRS combines a 2 MOA dot with selectable 8, 20, or 32 MOA circles. Its forward-leaning sunshade helps reduce glare, while Solar Failsafe, Shake Awake, memory, Lockout Mode, and a side-loading battery support reliable operation. The 7075-T6 aluminum housing uses the widely supported RMR mounting footprint.

Performance Reticle System

The Performance Reticle System provides a 2 MOA dot that can be used independently or combined with an 8, 20, or 32 MOA circle. The different circle sizes allow the sight picture to be adapted for precise aiming, rapid acquisition, or fast transitions between targets.

Enlarged Competition Window

The viewing window measures 1.18 × 0.98", approximately 30 × 25 mm. Its expanded surface provides a wider sight picture and more space for tracking the reticle during rapid target transitions.

Forward-Leaning Sunshade

The front of the housing extends into a forward-leaning sunshade designed to reduce glare in bright conditions. This helps preserve reticle clarity and keeps the sight picture easier to read when shooting under direct or changing light.

Solar Failsafe and Shake Awake

Solar Failsafe uses the integrated solar panel to supplement battery power. Shake Awake places the electronics into sleep mode after a period of inactivity and reactivates the sight when movement is detected. The memory function restores the previous settings, while Lockout Mode prevents accidental adjustments.

RMR Footprint and Side-Loading Battery

The sight uses the widely supported RMR mounting footprint for installation on compatible pistol slides and adapter plates. Power is supplied by a CR1632 battery housed in a side-loading tray, allowing it to be replaced without removing the optic from the firearm.

Up to 50,000 Hours of Battery Life

The CR1632 battery provides up to 50,000 hours of operation at brightness setting 6. The sight offers 8 daytime brightness settings and 4 settings compatible with night vision devices.

7075-T6 Aluminum Housing

The housing is machined from 7075-T6 aluminum and features an anodized finish. The sight is rated IP67 for protection against dust and water and withstands vibration loads of up to 5,000 G. Elevation and windage adjustments provide a range of ±30 MOA, with each click corresponding to 1 MOA.

Dimensions and Weight

The sight measures approximately 45.7 × 35.6 × 35.1 mm and weighs approximately 48 g. It provides true 1× magnification, unlimited eye relief, and multi-coated optical surfaces.
