Description
Versatile rifle optic combining rapid target acquisition and extended range capabilities in a single, battle-tested package.
Whether defending your home, competing in three-gun matches, or hunting at varied distances, this combo delivers the flexibility modern shooters demand. The HS510C provides lightning-fast target acquisition through its open reflex design and multiple reticle options, while the HM3X magnifier instantly extends your effective range to 200+ yards with a simple flip. Powered by both battery and solar backup, this system ensures your optic stays operational when it matters most, all while maintaining the durability to withstand harsh conditions and heavy recoil.
Key Features
- Three Reticle System: Switch between 2 MOA dot only, 65 MOA circle only, or circle-dot combo to match your shooting scenario—from close-quarters speed to precision at distance
- Dual Power Design: CR2032 battery provides up to 50,000 hours of operation on setting 6, backed by solar failsafe that keeps the reticle illuminated even if the battery dies
- Instant Magnification Toggle: Ambidextrous flip-to-side HM3X magnifier transitions seamlessly between 1x and 3x views without removing from your rifle
- Military-Grade Construction: Aluminum housing with titanium hood withstands 1,000G of recoil, submersible to 1 meter for 30 minutes (IP67), and operates in temperatures from -30°C to 60°C
Important Compatibility Notes
- Rail Space Requirement: This combo requires approximately 3.5-4 inches of Picatinny rail space (the HS510C occupies about 1.6 inches, the HM3X mount occupies approximately 2 inches)
- Height Matching: The HS510C sits at absolute co-witness height while the HM3X includes a spacer for lower 1/3 co-witness. To achieve matching lower 1/3 heights, you’ll need to purchase a separate riser for the HS510C
Why We Carry It
The HS510C earned widespread recognition as a legitimate competitor to optics costing twice its price, often compared directly to EOTech’s holographic sights due to its similar reticle pattern and open design. Unlike true holographic sights that use lasers, the HS510C uses more affordable LED technology while maintaining many of the same advantages. What makes this combo particularly valuable is the factory-matched pairing—the HM3X was specifically designed to work with Holosun’s red dot lineup, ensuring proper eye relief and optical alignment. Professional reviewers and competitive shooters have documented this setup performing reliably through thousands of rounds on platforms ranging from 5.56 ARs to hard-recoiling .308 rifles and 12-gauge shotguns.
Frequently Asked Questions
How difficult is zeroing the magnifier to match the red dot?
The HM3X includes windage and elevation adjustment turrets that allow you to zero the magnified view independently. The process involves zeroing your HS510C first, then flipping the magnifier into position and making minor adjustments until the magnified view matches your established zero.
Does the Shake Awake feature really work with the magnifier?
Yes. The HS510C’s motion-activated technology turns the optic on when it detects movement and powers down after several minutes of inactivity. This works regardless of whether the magnifier is flipped into position or not, as the technology is built into the red dot sight itself.
Can I use this combo on pistol caliber carbines or shotguns?
Yes, the HS510C is rated for 1,000G of recoil, and users have successfully mounted this combo on various platforms, including 9mm PCCs, .300 Blackout, and 12-gauge shotguns. The reflex sight design makes it particularly popular for competitive PCC shooting, where the large window enables faster target transitions.
