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 160g and has dimensions of 69x39x40mm. 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 no parallax and unlimited eye relief, 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 cap-secured slot giving it a running time of 50000 hours at a medium brightness setting.
The set includes a lower 1/3 Co-Witness mount, a low-profile mount, a universal key, a cleaning cloth, a rubber cover, and an installation set.
