Holosun HE515GT‑GR Micro Reflex for Sport Shooting & Hunting 2 MOA green dot und 2 MOA dot inside a 65 MOA circle

Holosun HE515GT‑GR Micro Reflex for Sport Shooting & Hunting 2 MOA green dot und 2 MOA dot inside a 65 MOA circle 

The Holosun HE515GT‑GR is a compact, closed‑tube green dot reflex sight built around a titanium housing and a 22 mm objective lens, making it one of the most versatile 1× optics in the Holosun 515 series. Its side‑mounted external battery compartment, ergonomic control buttons, and flip‑up lens covers keep the interface clean and intuitive, so the user can focus on sighting and observation rather than hunting for switches or panels. The quick‑detach Weaver/Picatinny mount allows fast attachment and removal, while the compact overall dimensions and low profile make it suitable for a wide range of applications, including rifles, carbines, certain air rifles, and crossbows used in European hunting and sport shooting.

Optical performance

The HE515GT‑GR uses a 1× (non‑magnifying) optical system with a 22 mm objective lens and multilayer coated glass, delivering bright, clear images with minimal distortion. The reticle system is Two‑MOA with Circle, offering two main modes:

• A 2 MOA green dot for precise aiming at mid‑to‑long distances.
• A 2 MOA dot inside a 65 MOA circle for rapid target acquisition at close range.

These markings are visible in both daylight and night‑vision‑compatible modes, thanks to 12 brightness levels (10 daylight + 2 NV). The green wavelength (≈540 nm) is easier on the eye than red and provides better contrast against natural backgrounds, which is particularly useful in forested or mixed‑light environments.

Technology & reliability

Powered by a single CR2032 (3 V) battery, the HE515GT‑GR can operate for up to 50,000 hours in the 2 MOA dot‑only mode at moderate brightness. The Shake Awake technology automatically turns the reticle off after a programmable idle period (adjustable from 2 to 12 hours, factory default 8 hours) and remembers the last brightness level, so the sight is ready as soon as you pick it up.

The housing is made from titanium, with a matte black finish, IPX8 waterproofing (submersible up to approximately 30 meters), and nitrogen filling to prevent fogging. The unlimited eye relief and parallax‑free image ensure consistent reticle placement regardless of head position, which is especially useful for dynamic shooting or compact hunting rigs.

Technical Specifications Holosun HE515GT‑GR 

Practical use in Europe

For European sport shooters and hunters, the HE515GT‑GR excels in mixed‑light conditions, where the green reticle stands out clearly against green foliage and low‑contrast backgrounds. The compact titanium body and quick‑detach mount make it easy to swap between different platforms, while the flip‑up lens covers and nitrogen‑filled optics help maintain performance in humid or rainy weather. The unlimited eye relief and 1× imaging fit well with both sport‑oriented shooting disciplines and traditional hunting setups.

Frequently asked questions
What is the battery life of the Holosun HE515GT‑GR?
The Holosun HE515GT‑GR is a reflex optic that combines Holosun’s Green Super LED and Shake Awake technology to deliver an exceptionally long battery life. In typical use, the green‑dot configuration can last up to about 50,000 hours when using the small 2 MOA dot alone, and roughly 20,000 hours when both the 2 MOA dot and the 65 MOA circle are active. The side‑mounted battery compartment allows quick, tool‑free replacement. For European sport shooters and hunters, this efficient power management makes the HE515GT‑GR a reliable red dot sight for long‑duration outings and frequent training sessions without constant battery changes.

What reticle system does the HE515GT‑GR use?
The Holosun HE515GT‑GR features Holosun’s Multi‑Reticle System (MRS), which gives you multiple aiming patterns in a single compact red dot sight. You can switch between a precise 2 MOA green dot for longer‑range precision and a 2 MOA dot inside a 65 MOA circle for faster target acquisition at close to mid‑ranges. The MRS cycles through these patterns with one control button, allowing you to adapt the reticle to different shooting distances and conditions without changing optics. For European hunters and sport shooters, this flexibility means the same Holosun HE515GT‑GR can support everything from careful target practice to driven‑game scenarios in densely wooded terrain, making it a versatile reflex optic for everyday use.

What is the difference between green and red dot on the HE515GT‑GR?
The Holosun HE515GT‑GR uses a green‑dot version of Holosun’s Super LED, which often appears brighter and more vivid in many ambient light conditions, especially in daylight and under green‑tinted foliage. Green light can also be easier to see for some users with red‑green color challenges, which is helpful for hunters and sport shooters who need quick, clear target acquisition. Compared with a standard red dot sight, the green dot of the HE515GT‑GR can provide better contrast against certain natural backgrounds and in some low‑light situations, although both green and red reflex optics remain effective across typical outdoor conditions. The choice between green and red usually comes down to personal preference, but the HE515GT‑GR’s green‑dot design is particularly popular in European hunting environments where green landscapes dominate.

How durable and weather‑resistant is the Holosun HE515GT‑GR?
The Holosun HE515GT‑GR is built around a robust 7075‑aluminum housing designed for field use in demanding outdoor conditions. It is rated to withstand strong vibration and shock, with a working temperature range of about −30 °C to +60 °C and an IPX8‑level of water and dust resistance, meaning it can even be submerged in water and still operate reliably. For European hunters and sport shooters, this means the reflex optic can handle rain, snow, bumps from rough handling, and long‑term use in the field without noticeable loss of performance. When paired with a quality mount, the HE515GT‑GR functions as a dependable green‑dot sight that performs consistently in the varied climates and terrain found across Europe.

Is the HE515GT‑GR compatible with common mounting platforms?
The Holosun HE515GT‑GR is designed as a compact micro‑red‑dot sight with a standard footprint, making it compatible with widely used mounting platforms found on many European sport and hunting setups. It typically comes with or can be paired with a quick‑detach (QD) riser or Picatinny‑compatible mount, allowing it to attach to rail or rail‑style interfaces without needing a fully custom adapter. As part of Holosun’s 515 micro‑optic family, many existing mounts and accessories for this series are compatible with the HE515GT‑GR, increasing its versatility for both gunsmiths and end users. Holosun Croatia, as an authorized Holosun dealer, can advise on suitable mounts and help ensure proper eye relief and co‑witness setup for your specific configuration.

What warranty does Holosun offer in the EU?
Holosun provides an official EU warranty on its optics, including the Holosun HE515GT‑GR, through its European network and authorized dealers. The standard warranty covers the glass, LED illumination, and electronic components for several years from the date of original retail purchase, provided the optic is used under normal personal‑use conditions. As an authorized Holosun dealer in Croatia, Holosun Croatia can handle warranty claims, service support, and inspections locally, so you do not need to ship the reflex optic outside the EU. This gives European sport shooters and hunters peace of mind, knowing that any manufacturing‑related issue with their Holosun red dot sight can be resolved through an official EU‑based service channel and supported by the official EU warranty.

Is the HE515GT‑GR suitable for hunting in Europe?
The Holosun HE515GT‑GR is well suited to European hunting scenarios thanks to its compact size, bright green dot, and multi‑reticle system that adapts to different shooting distances. The 2 MOA dot provides precision for longer‑range shots, while the 65 MOA circle‑and‑dot combination supports fast aiming in close‑quarters or driven‑game situations typical in European forests and mixed‑terrain areas. Its robust construction, IPX8 rating, and broad temperature tolerance allow it to perform reliably through the variable weather Europe can present, from cold winter mornings to humid spring days. For hunters who value speed, durability, and optical clarity, the HE515GT‑GR stands out as a practical green‑dot reflex optic for a wide range of European game and cover types.

Can the HE515GT‑GR be used effectively for sport shooting?
Yes, the Holosun HE515GT‑GR is an excellent choice for sport shooting disciplines that require fast, repeatable target acquisition. The 2 MOA green dot delivers fine precision for target practice and accuracy‑oriented drills, while the 65 MOA circle supports rapid transitions between targets during speed‑oriented courses. Shake Awake technology keeps the reflex optic ready and efficient during long training sessions, reducing the need to toggle illumination on and off manually. As an officially supported Holosun reflex sight in the European market, the HE515GT‑GR is a versatile green‑dot optic that can grow with a shooter’s skill level, from recreational plinking to more structured, competition‑style training.
