Holosun HE407C GR X2 Open Style Red Dot Style Sight – 2 MOA Green Dot, 10 Day / 2 Night Brightness, 50 000 h Potential

Holosun HE407C‑GR‑X2 – Open‑Elite 2 MOA Green Dot Sight with Solar‑Failsafe

The Holosun HE407C‑GR‑X2 is an open‑style reflex sight from the popular 407‑series, designed for compact firearms and rail‑mounted platforms in European sport‑shooting and professional‑style applications. The unit is supplied without a mounting base, allowing flexible integration directly onto Weaver‑/Picatinny‑style rails or pistol slides with RMR‑pattern machining (Glock MOS, Walther P99, soft‑air, etc.). The 7075‑T6‑aluminum body, 50 × 32 × 40 mm footprint and 75 g weight (43 g without mount plate) provide a robust yet compact option that sits low and unobtrusively on the host platform.

Optically, the HE407C‑GR‑X2 features a 23 × 16 mm lens and a parallax‑free 1x optical path with a clearly visible 2 MOA green dot at approximately 505 nm, giving precise aiming at short and medium distances. The sight offers 12‑level illumination modes: 10‑level daytime (including two very dim, night‑vision‑compatible levels) and 2‑night‑vision settings, enabling use in both daylight and low‑light or PNV‑assisted conditions. Brightness can be adjusted manually via the side‑mounted “+” and “–” buttons, or set to automatic mode, where the integrated solar element acts as a light‑sensor and dynamically matches the dot intensity to ambient light. The automatic brightness‑remember function keeps the last‑used setting once the unit wakes up.

Power comes from a CR2032H 3 V lithium battery installed in the base of the housing and supplemented by an integrated solar panel that implements Solar‑Failsafe and Shake‑Awake. In Solar‑Failsafe, the unit can remain functional on solar energy alone when the battery is weak, as long as there is sufficient ambient light, while the solar panel also supports brightness‑adaptation. Shake‑Awake switches the sight into sleep mode during extended inactivity, then reactivates the dot with the last‑used brightness as soon as movement is detected, significantly extending effective runtime and reducing the need for frequent battery swaps. The robust IP67 rating protects the interior from dust and water, including short‑term submersion, and the housing can operate reliably in the –10 °C to +50 °C temperature band.

Mechanically, the HE407C‑GR‑X2 provides 1 MOA‑per‑click adjustments (H/V) with ±50 MOA travel, allowing accurate, repeatable zeroing for a wide range of firearms. The elevation and windage screws are recessed and designed to be adjusted with the included hex tools so that over‑rotation is avoided. The rear‑positioned, slightly recessed buttons also prevent accidental presses when the firearm is holstered or handled, while the button‑lock mode (activated by long‑pressing the “+” button for 3 seconds) blocks unintentional brightness changes during transport or carry. Order the Holosun HE407C‑GR‑X2 without base from Holosun Croatia and integrate a compact, solar‑enhanced green‑dot reflex sight with automatic brightness, 12‑level illumination, IP67 protection and long‑term reliability into your next EU‑market build.

Frequently Asked Questions – Holosun HE407C‑GR‑X2

What is the battery life and power system of the Holosun HE407C‑GR‑X2?
The Holosun HE407C‑GR‑X2 uses a CR2032H 3 V lithium battery combined with an integrated solar panel that supports the Solar‑Failsafe and Shake‑Awake features. Under typical conditions and moderate brightness, this open‑style reflex optic can provide up to 50 000 hours of estimated runtime, significantly extending the interval between battery changes. Shake‑Awake switches the 2 MOA green dot into a low‑power sleep mode during inactivity and reactivates it with the last‑used brightness as soon as movement is detected. This energy‑efficient design makes the Holosun HE407C‑GR‑X2 exceptionally suitable for European‑style sport‑shooting sessions, long‑range blocks, and field‑oriented builds, where low‑maintenance operation and long‑term reliability matter more than frequent maintenance stops.

How does the 2 MOA green dot reticle work in the Holosun HE407C‑GR‑X2?
The Holosun HE407C‑GR‑X2 features a simple 2 MOA green dot at approximately 505 nm, optimized for quick and precise target acquisition. The 2 MOA size is small enough to allow fine‑range aiming but large enough to remain easily visible in dynamic shooting situations. The green illumination provides excellent contrast against many backgrounds and tends to appear brighter to the human eye than an equivalent red dot, especially at lower light levels. The optic offers 12‑level illumination (10‑day + 2‑night‑vision‑compatible levels), so the green dot can be finely tuned for daylight, dusk, or low‑light conditions. As a compact green‑dot reflex optic, the HE407C‑GR‑X2 suits European‑oriented sport‑shooting setups where a clean, uncluttered reticle and fast target re‑acquisition are important.

What are the advantages of a green dot vs red dot in the HE407C‑GR‑X2?
The Holosun HE407C‑GR‑X2 uses a green dot instead of a traditional red‑dot configuration, which can offer several practical benefits for European users. Green light at around 505 nm generally appears brighter and more vivid than an equivalent red dot in normal daylight, especially on foliage‑rich or mixed‑tone backgrounds, improving comfort during long‑duration shooting sessions. The 2 MOA green dot remains highly visible on screens and night‑vision‑compatible viewing, even at the lower brightness stages that are invisible to the naked eye. In many environments, the green dot also creates slightly better contrast than red, which can speed up target re‑acquisition without adding visual clutter. For sport shooters and field‑oriented users, the green‑dot version of the Holosun HE407C‑GR‑X2 provides a brighter, more adaptable aiming reference while keeping the compact, open‑type reflex‑optic form factor intact.

How durable and weather‑resistant is the Holosun HE407C‑GR‑X2?
The Holosun HE407C‑GR‑X2 is built from 7075‑T6‑aluminum and rated to IP67, meaning it is fully protected against dust and brief submersion in water. The open‑style housing is designed to resist mechanical shock, repeated handling, and field‑oriented use, while the 2 MOA green dot remains stable across a –10 °C to +50 °C operating range—covering most European weather conditions. The optic can stay calibrated even after frequent transport and repeated mounting and dismounting, as long as installation torque is kept within recommended limits. This combination of rugged 7075‑T6 construction and IP67 protection makes the Holosun HE407C‑GR‑X2 a reliable choice for wet, humid, or dusty environments, where corrosion‑resistant, sealed‑type reflex optics are preferred. European sport‑shooting users benefit from long‑term reliability with minimal maintenance in typical outdoor settings.

What kind of rail systems and platforms is the HE407C‑GR‑X2 compatible with?
The Holosun HE407C‑GR‑X2 is supplied without a fixed mounting base, which increases its adaptability across platforms. It can be mounted directly onto standard Weaver‑/Picatinny‑style rails commonly used on many European‑oriented optics carriers and rail‑based accessories. The unit can also be installed on platforms with RMR‑pattern screw holes, making it compatible with a wide range of rail‑mounted hardware, including pistol‑style and rifle‑type rail modules, when using the appropriate RMR‑pattern plate. The compact 50×32×40 mm footprint and 75 g weight allow the reflex optic to sit low and maintain a balanced profile, preserving natural handling and visual alignment.
