The Holosun HS510C-FDE Open Reflex Red Dot Sight is engineered for broad compatibility across various long gun platforms. This optic features Holosun’s Multi-Reticle System (MRS), providing the user with three distinct reticle options: a precise 2 MOA dot, a 65 MOA circle, or a combination of both. Reticle selection is managed via a simple button press, allowing adaptation to different shooting scenarios.
Powering the HS510C-FDE is a dual system that combines a CR2032 battery with an efficient solar power backup. This design ensures consistent operation and extended battery life. The optic’s internal components are protected by a durable titanium alloy housing, built to withstand challenging conditions. Its open frame design facilitates an unobstructed field of view, critical for rapid target acquisition. Equipped with a quick release (QR) mount, this sight can be swiftly installed or removed from compatible rails.
As a robust addition to any collection of firearm accessories, the HS510C-FDE is well-suited for applications ranging from competition on the shooting range equipment to practical use with personal defense firearms. This tactical optic offers reliability and versatility for informed users.
