Holosun HE510C-GR Open Reflex Green Dot Sight & HM3X 3x Magnifier Tactical Combo - HE510CGRHM3X

Product Description

Equipping a modern sporting rifle, tactical carbine, or home-defense platform for fluid transitions between close-quarters indexing and mid-range precision reveals an immediate visual and mechanical bottleneck: optics compromise. Running a standalone 1x reflex sight lacks the target definition needed to confidently identify targets past 100 yards, while traditional magnified scopes introduce narrow eye-boxes and slow down close-range response splits. The **Holosun® HE510C-GR and HM3X Magnifier Combo** completely eliminates these operational limits, packaging a professional-grade open reflex green dot sight and an unyielding, flip-to-side 3x magnifier into a single, factory-matched tactical engine built for complete situational authority.

Precision-engineered from premium materials to withstand intense firing schedules, the foundation of this pairing begins with the iconic **HE510C-GR Open Reflex Sight**. Shielded inside a ruggedized **titanium alloy protective hood**, the sight features a massive panoramic window that enables effortless both-eyes-open tracking. At the core of its optical engine is Holosun's high-efficiency **Green Multi-Reticle System (MRS)**, allowing operators to instantly cycle between a precise 2 MOA center dot, a wide 65 MOA CQB speed ring, or a combined circle-dot layout. Utilizing a crisp green laser diode, it leverages human visual physiology to speed up physical indexing while drastically reducing eye strain under harsh sunlight. Powered by Holosun’s advanced Super LED matrix, it features an extraordinary **50,000-hour battery life**, reinforced by a failsafe **Solar Failsafe™ ambient panel** and ultra-responsive **Shake Awake™ sensor logic** that instantly wakes the reticle from sleep mode upon the slightest movement.

To seamlessly extend your tactical tracking envelope downrange, the package includes the battle-proven **HM3X 3x Magnifier**. Wrapped inside a durable, non-reflective matte black anodized aluminum housing, this magnifier features premium multi-coated, nitrogen-purged glass lenses that yield exceptional light transmission and edge-to-edge optical clarity. The HM3X features a highly forgiving **2.75-inch eye relief** and tool-free internal windage and elevation centering dials, keeping your green MRS reticle perfectly squared in your field of view. Mounted on an unyielding **Flip-to-Side Quick-Detach (QD) mounting block**, a simple physical slap toggles the magnifier into position for intermediate precision or flips it completely out of your primary sight line for close-quarters panoramic engagement.

*Armorer Bench Notes & Technical Assembly Guidance: The Holosun HE510CGRHM3X combo arrives factory-calibrated to mount natively onto any standard MIL-STD 1913 Picatinny receiver rail. Out of the box, both units are configured for an industry-standard **absolute cowitness height (1.41 inches)** from the top of the rail to the optical centerline. However, the HM3X retail package includes a specialized spacer shim and matching extended hex screws on your workbench. If you intend to elevate your layout to a lower 1/3 cowitness profile, you must install this spacer block beneath the magnifier mount to perfectly realign the optical axes. When securing the components on your bench, adjust the quick-detach cam-tension nuts until the mounts clamp flush onto the rail without side-to-side wobble. Apply a micro-drop of medium thread locker to the magnifier hinge pins to prevent backing out under heavy cyclic recoil forces.
