⚙️ Product Details

Extend your effective shooting range with the Holosun HS510C Open Reflex Red Dot Sight and Holosun HM3X 3X Magnifier Combo, the perfect pairing for any shooter looking for accuracy, versatility, and convenience. With this combo, you get everything you need—no need to worry about finding compatible optics, magnifiers, and riser heights.

The HS510C Open Reflex Circle Dot Sight offers a wide sight picture thanks to its open frame design, making target acquisition fast and easy. Powered by both solar cells and a back-up CR2032 battery, this optic can run continuously in any lighting condition. The Multi-Reticle System lets you quickly switch between a 65 MOA circle with a 2 MOA dot or a 2 MOA dot only, and because both reticles are projected from the same LED, you don’t need to re-zero when switching between them.

Paired with the Holosun HM3X Magnifier, this combo lets you quickly transition from 1x to 3x magnification with its flip-to-side design. The HM3X provides generous eye relief, an adjustable diopter for a custom focus, and a quick-detach mount with a spacer for compatibility with both absolute and lower 1/3rd co-witness red dot mounts. Together, the HS510C and HM3X magnifier deliver a versatile and durable solution for shooters who need to switch between close-quarters combat and longer-range engagements.

HS510C Features:

Multi-Reticle System: Switch between a 65 MOA circle with a 2 MOA dot or a 2 MOA dot only at the push of a button—no re-zeroing required.
Dual Power Supply: Solar cell for normal usage and a CR2032 battery for low-light conditions, offering long-lasting performance.
Parallax-Free Design: With unlimited eye relief, this optic offers fast target acquisition and precise aiming, no matter your position.
Durable Construction: Shock-resistant titanium alloy protective hood and CNC-machined 6061-T6 aluminum housing ensure durability.
Quick Release Mount: Adapts to Picatinny and Weaver rails with ease, making installation simple and secure.

HM3X Magnifier Features:

3X Magnification: Extend your effective range with this 3x magnifier, perfect for mid- to long-range engagements.
Flip-to-Side Design: Quickly switch between 1x and 3x magnification with the easy-to-use flip-to-side mechanism.
Adjustable Diopter: Customize your focus for clear, crisp views with the adjustable diopter ring.
Durable Build: Built with aluminum housing and a matte black finish, this magnifier is made to the same rugged standards as Holosun’s red dot sights.
QD Mount and Spacer: Quick-detach mount with a spacer allows compatibility with both absolute and lower 1/3 co-witness optics.

Upgrade your shooting setup with the Holosun HS510C and HM3X Magnifier Combo for unmatched versatility, precision, and durability. Whether you're shooting in close quarters or at extended ranges, this combo provides the perfect balance of technology and performance to enhance your accuracy and effectiveness.
