Holosun HE503RGD Red Dot Sight 2 MOA Gold Dot 65 MOA Circle

The Holosun HE503RGD delivers precision targeting with its dual reticle system featuring a crisp 2 MOA gold dot and 65 MOA circle for rapid target acquisition. This enclosed red dot sight combines Holosun's advanced LED technology with rugged construction to provide reliable performance across multiple shooting disciplines.

What Makes This Different

The HE503RGD stands apart with its gold reticle option, offering enhanced visibility against varied backgrounds compared to standard red dots. The enclosed design protects the LED emitter from debris and impacts while maintaining the open sight picture shooters prefer. Solar failsafe technology extends battery life significantly beyond conventional red dot sights, with up to 50,000 hours of operation on setting 6.

Key Features

• Dual reticle system: 2 MOA gold dot with 65 MOA circle for versatile aiming options
• Solar failsafe with side-loading CR2032 battery compartment

Field testing demonstrates consistent zero retention through temperature extremes and heavy recoil. The gold reticle proves particularly effective in bright sunlight and against light-colored targets where red dots can wash out. Competition shooters benefit from the large circle for rapid close-range engagement, while the precise dot enables accurate shots at extended distances. The sight maintains zero through thousands of rounds across multiple platforms.
