Description

Mini-sized closed red dot sight made by Holosun.
CNC machined from 6061-T6 aluminum alloy oxidized with matte black coating, this mini-sized sight weighs 138g and has dimensions of 71x36x69mm. An IP67 rating makes it water and dust resistant as well as shock-proof.
The 20mm lens glass is covered in anti-scratch and reflection multi-coating. 2 MOA-sized red dot with a 65-sized circle and a 1/2 MOA adjustment value is available. An LED provides two NV modes and ten brightness levels and is adjustable by a side knob. With less than 1 MOA of parallax, unlimited eye relief, and 50 MOA of windage and elevation adjustment range, HS503R guarantees quick and accurate target acquisition in all weather and light conditions.
The power is provided by a single CR2032 battery in a screw-secured tray giving it a running time of 50000 hours at a medium brightness setting. It also features rubberized controls and a "Shake Awake" system that helps conserve the battery. The additional solar panel on top and the "Solar Failsafe" system amplifies brightness settings.
The set includes a lower 1/3 Co-Witness mount, a low-profile mount, a cleaning cloth, a rubber cover, and an installation set.
