Holosun 507-PROMAX Red Dot PRS RMR pistol reflex sight, black (SKU: HS507-PROMAX-RD-PRS / 48861) is an open reflex sight designed for sport shooting. The enlarged 30 × 25 mm window facilitates viewing with both eyes open. An integrated, forward-leaning sunshade reduces glare, while multilayer optical coatings support light transmission.

The PRS (Performance Reticle System) offers eight red reticle configurations using a 2 MOA dot, 8, 20 and 32 MOA circles and their combinations. Brightness can be adjusted automatically or manually. There are 12 illumination levels: 8 daylight settings and 4 compatible with night vision devices. Lock Mode locks the buttons to prevent accidental setting changes.

The CR1632 battery sits in a side tray, allowing replacement without removing the sight. In automatic mode, the Solar Failsafe panel provides backup power under sufficient lighting. Shake Awake turns off illumination during inactivity and restores it when motion is detected, retaining the last brightness setting. According to the manual, the stated battery life is up to 100,000 hours with the dot only at brightness setting 6.

The housing is made from hard anodized 7075-T6 aluminium. The sight has an IP67 ingress protection rating and a stated vibration resistance of up to 5000 G. Its RMR footprint is compatible with a matching mounting interface or a suitable adapter plate selected for the specific pistol.
