The HS507COMP uses Holosun's CRS multi-reticle system, offering dot and circle-dot combinations in a bright red reticle. This gives the user clear, adaptable options for different shooting preferences while maintaining a crisp, defined aiming point.
The optic's open-reflex design pairs with an anti-reflective green/blue lens tint to help maintain a clear sight picture. Its matte black housing provides a low-glare finish, and the unit remains lightweight at approximately 1.7 oz with compact dimensions around 1.8 x 1.3 x 1.3 inches.
Mounting is supported by RMR-pattern recoil-lug recesses and rear threaded holes. Adjustment is straightforward with a right-side windage screw marked with an "R" arrow for reference.
Power is supplied by a CR1632 battery housed in a side battery tray secured by a slotted retaining screw, allowing battery access without disturbing the mounting interface. The HS507COMP carries an MSRP of $435.
