Holosun HE403B-GR Elite Micro Green Dot Sight 2 MOA Shake Awake
The Holosun HE403B-GR Elite Micro stands as a compact enclosed green dot sight tailored for pistols, shotguns, crossbows, and air rifles on Weaver/Picatinny rails, featuring a crisp 2 MOA Super Green LED dot at 540 nm for superior visibility in low light or foliage-heavy environments. Its parallax-free 20 mm multi-coated lens with unlimited eye relief enables rapid both-eyes-open targeting at close to medium ranges, ideal for hunters, airsoft players, and tactical shooters needing lightweight precision. The internal slide-out battery tray houses a CR2032 for tool-free access, paired with top-mounted brightness controls and dual Weaver mounts (low/high) for versatile setups.
Advantages deliver elite performance with 50,000-hour battery life through Shake Awake motion activation and memory recall, IP67 dust/water sealing for all-weather reliability, and green LED 4x more efficient than red—outshining competitors in contrast and runtime at competitive prices. The 6061-T6 aluminum housing with MAO finish resists corrosion better than anodizing, weighing just 121 grams for minimal bulk.

Frequently Asked Questions
How long does the battery last on the Holosun HE403B‑GR green‑dot sight?
The Holosun HE403B‑GR green‑dot sight runs on a single CR1632 battery and offers up to 50,000 hours of runtime on the mid‑brightness settings under typical European sport‑shooting and hunting use. This impressive battery life is achieved through an efficient LED emitter and Holosun’s “Shake Awake” motion‑detect system, which powers the sight only when movement is detected and enters low‑power standby when idle. For European users, this means the Holosun HE403B‑GR reflex optic can often remain installed for months or even years without needing a battery swap, reducing maintenance and downtime. The combination of a long‑life power source and a solar‑aware design makes this Holosun HE403B‑GR 2 MOA green‑dot sight a practical, low‑maintenance red‑dot‑style reflex optic for regular range sessions, hunts, and outdoor training.
What kind of reticle does the Holosun HE403B‑GR use?
The Holosun HE403B‑GR green‑dot sight features a 2 MOA central green‑dot reticle designed for fast, intuitive target acquisition with a clear and uncluttered sight picture. Unlike some Holosun models that use the Multi‑Reticle System (MRS), the HE403B‑GR is built around a single, fixed 2 MOA aiming point, which stays consistent across different lighting and environmental conditions. The 2 MOA dot is small enough for precision at medium distances yet large enough to deliver a fast, visible reference for close‑range work. For European sport shooters and hunters, the Holosun HE403B‑GR 2 MOA green‑dot reflex optic combines a familiar open‑reflector layout with a high‑contrast green‑dot‑type reticle that performs well in mixed‑light European conditions, making it a straightforward alternative to a classic red‑dot sight.
Does the Holosun HE403B‑GR use MRS like other Holosun reflex sights?
No, the Holosun HE403B‑GR green‑dot sight does not use Holosun’s Multi‑Reticle System (MRS). It is a dedicated 2 MOA green‑dot reflex optic without selectable dot‑plus‑ring or multiple reticle‑pattern modes. MRS‑equipped Holosun models allow switching between several configurations (for example, 2 MOA dot, 6 MOA ring, or both), while the HE403B‑GR keeps operation very simple with a single clean aiming point. This simplicity suits many European sport shooters and hunters who prefer a no‑nonsense, one‑reticle setup for training, club sessions, and field use. You still get the benefits of a bright, easy‑to‑see 2 MOA green‑dot‑style ring, but without the need to change patterns or memorize additional modes on the Holosun HE403B‑GR reflex optic.
What is the difference between a green‑dot and a red‑dot sight like the Holosun HE403B‑GR?
Green‑dot and red‑dot reflex optics both project an illuminated aiming point, but the human eye generally perceives a green‑dot‑type target as slightly brighter in shaded or low‑light settings, especially against dark backgrounds. Red‑dot sights usually work a bit better in very bright daylight and may consume marginally less power, extending theoretical runtime by a small amount. The Holosun HE403B‑GR green‑dot sight uses a 2 MOA green‑dot reticle that behaves like a green‑dot‑style optic, providing strong visibility in mixed‑light forests, at dusk, or on overcast days while still maintaining efficient battery use. For European hunters and sport shooters, this Holosun HE403B‑GR reflex optic feels closer to a green‑dot‑type sight for perceived brightness, yet retains the low‑maintenance, red‑dot‑style convenience and ease of use they expect from a modern Holosun red‑dot‑style green‑dot sight.
Is the Holosun HE403B‑GR 2 MOA green‑dot sight durable enough for outdoor and hunting use in Europe?
Yes, the Holosun HE403B‑GR 2 MOA green‑dot sight is built as an open‑reflex optic with a rugged aluminum housing and an IP67‑rated sealed design that resists water, dust, and mechanical shock. This level of robustness makes the Holosun HE403B‑GR well suited for demanding outdoor conditions typical of European sport‑shooting and hunting environments, including cold, wet, or dusty terrain. The green‑dot sight maintains its zero under repeated recoil‑like vibrations and rough handling as long as the mounting hardware is correctly torqued. For European users, its IP67‑style sealing, shock‑resistant build, and robust internal electronics make the Holosun HE403B‑GR green‑dot reflex optic a dependable, field‑ready choice for repeated seasons in the field without frequent recalibration or maintenance.
What durability and environmental specs should I expect from the Holosun HE403B‑GR reflex optic?
The Holosun HE403B‑GR green‑dot sight is engineered with an IP67‑rated, sealed housing and an open‑reflex layout that resists water immersion, dust ingress, and impact. It operates reliably across a wide temperature range and is built to withstand the vibrations and bumps typical of active outdoor use. The 2 MOA green‑dot reticle is supported by a durable lens and robust electronics, ensuring long‑term clarity and stable performance for both hunting and sport‑shooting sessions. European shooters can treat the Holosun HE403B‑GR as a fixed‑mount, short‑to‑medium‑range reflex optic where the main maintenance tasks are regular cleaning of the front aperture and occasional checking of the zero after transport or hard handling. The combination of an IP67‑rated build, efficient battery system, and strong housing makes this Holosun HE403B‑GR 2 MOA green‑dot sight highly suitable for long‑term use in tough European field conditions.
How well does the Holosun HE403B‑GR 2 MOA fit on different platforms in Europe?
The Holosun HE403B‑GR green‑dot sight uses a compact, low‑profile footprint compatible with many common European‑market mounting standards, allowing straightforward installation on a wide range of sport‑shooting and hunting setups in most cases without proprietary adapters. The open‑reflex design keeps the sight low over the platform, which helps maintain the option to use existing backup mechanical sights if they are available on the same setup. As an official Holosun retailer in the EU, Holosun Croatia (and Professional Optics in Split, Croatia, acting as an authorized Holosun dealer) can advise on suitable mounting hardware and alignment techniques, ensuring a secure, repeatable fit across different platforms while avoiding misalignment or cant. This versatility makes the Holosun HE403B‑GR 2 MOA green‑dot sight a practical reflex optic for European sport shooters and hunters who use multiple shooting or hunting configurations.
What warranty cover does the Holosun HE403B‑GR green‑dot sight have in the EU?
The Holosun HE403B‑GR 2 MOA green‑dot sight is covered under Holosun’s Limited Lifetime Warranty, with the metal housing and core optical system typically protected for the life of the product when purchased from an authorized Holosun dealer in the EU. The illumination system, including the LED and “Shake Awake” circuitry, is commonly covered for an extended multi‑year period, in line with EU‑based practices for premium optics. When you buy the Holosun HE403B‑GR green‑dot sight from an official EU retailer such as Holosun Croatia or Professional Optics in Split, you receive full access to this official EU warranty, complete with local support and a streamlined service process instead of shipping the Holosun HE403B‑GR reflex optic back to non‑EU locations. For European sport shooters and hunters, this combination of robust green‑dot‑style performance and a long‑term official EU warranty makes the Holosun HE403B‑GR 2 MOA green‑dot sight a reliable investment for active outdoor environments.
