The Holosun 507 Gold Multi-Reticle Open Lens Solar Shake Awake 7075 Aluminum Miniature Pistol Reflex Sight is a versatile, fast-acquisition pistol optic built for competition, duty, and everyday carry use. It features a multi-reticle system displaying a gold 2 MOA dot, an 8 MOA circle, and a combined 2 MOA dot inside the 8 MOA circle, letting shooters choose the reticle configuration that best suits their preference and shooting situation. The open-lens design offers a broad field of view with unlimited eye relief and parallax-free performance at typical handgun distances. Constructed from durable 7075-T6 aluminum with a hard-anodized finish, the sight includes Shake Awake technology to conserve battery life and solar-assisted power management to further extend runtime—often providing thousands of hours of use from a single CR2032 battery. With precise 1 MOA windage and elevation adjustments, an IP67 waterproof rating, and rugged construction, the HS507C-GD-X3 delivers dependable performance for a wide range of pistols and shooting applications.
