Thanks to its sealed construction, the emitter and lenses are protected from dust, mud, and water, ensuring reliable performance in harsh terrain and weather conditions.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eClear image and parallax minimized to an imperceptible level\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe optical system of this model is based on a 20 mm diameter lens, which provides a bright and clear image thanks to multi-layer FMC anti-reflective coatings that ensure optimal light transmission and high contrast. Parallax has been minimized to an imperceptible level in the collimator. This, combined with an unlimited eye relief, ensures high comfort and enables intuitive binocular aiming.\u003c\/p\u003e \u003cp\u003eTransparent flip-back protective covers keep the outer lenses clean and protect them from dirt, scratches, and rain. Additionally, the set includes a removable honeycomb-structured sunshade that effectively eliminates light reflections from the front sight lens, preventing the shooter’s position from being revealed.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eStable power supply and energy-saving system\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe device is powered by a single CR2032 lithium battery, which provides up to 50,000 hours of operation. Energy-saving is ensured by Shake Awake technology, which automatically turns off the reticle illumination during inactivity and immediately restores it to the last-used mode upon detecting movement, eliminating the need for manual control of the sight during use.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eMRS System and Reticle Illumination and Position Adjustment\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe HE515GT-RD model is equipped with the MRS system. It allows the user to choose between two red reticles—a 2 MOA dot or a 65 MOA dot in a circle—without losing zero. The shooter has 12 brightness levels at their disposal, consisting of 8 daytime modes and 4 modes designed for use with night vision devices. The adjustment range of the reticle in the vertical and horizontal planes is +\/- 50 MOA with a click value of 0.5 MOA.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eTitanium body, high durability, and stable optical axis\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe device’s body is made of titanium. This ensures exceptional mechanical strength and corrosion resistance while maintaining a low weight. The design features an IPX8 waterproof rating, allowing the red dot sight to remain functional after submersion in water, and shock resistance up to 1000G enables trouble-free use on high-recoil firearms.\u003c\/p\u003e \u003cp\u003eThe red dot sight remains fully functional in extreme operating temperatures ranging from -40°C to 60°C. The included mount allows for stable mounting of the red dot sight on a Picatinny rail, raising the sight’s optical axis to a height of 36 mm above the rail. This dimension defines the mount profile as Absolute Co-witness, in which the red dot aligns with standard-height mechanical sights.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e\n\n\u003cli\u003eEnclosed red dot sight with a 20 mm tube diameter\u003c\/li\u003e \u003cli\u003eDurable housing made of lightweight titanium\u003c\/li\u003e \u003cli\u003eIncludes transparent flip-back lens covers\u003c\/li\u003e \u003cli\u003eRemovable Killflash sunshade to eliminate light reflections\u003c\/li\u003e \u003cli\u003eMRS system allowing selection of a 2 MOA dot or a 65 MOA circle\u003c\/li\u003e \u003cli\u003ePowered by a high-capacity CR2032 lithium battery providing up to 50,000 hours of operation\u003c\/li\u003e \u003cli\u003eBattery-saving Shake Awake system with memory of the last used mode\u003c\/li\u003e \u003cli\u003e12 brightness levels for the red dot, including 4 optimized for night vision\u003c\/li\u003e \u003cli\u003eParallax minimized to an imperceptible level\u003c\/li\u003e \u003cli\u003eIPX8 waterproof rating ensuring full water resistance when submerged\u003c\/li\u003e \u003cli\u003eHigh resistance to vibrations and shocks up to 1000 G\u003c\/li\u003e \u003cli\u003eStable Picatinny rail mount providing an Absolute Co-witness optical axis\u003c\/li\u003e\n\n\n\u003c\/ul\u003e \u003cp style=\"display: none;\"\u003esplitter\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e\u003ctable width=\"100%\" class=\"product-data-table\"\u003e \u003cthead\u003e \u003ctr\u003e\u003cth colspan=\"2\"\u003eTechnical Specifications\u003c\/th\u003e\u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e\n\n\u003ctd\u003eLight source\u003c\/td\u003e\n\n\u003ctd\u003eLED\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eLED wavelength\u003c\/td\u003e\n\n\u003ctd\u003e650 nm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eReticle color\u003c\/td\u003e\n\n\u003ctd\u003eRed\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eReticle\u003c\/td\u003e\n\n\u003ctd\u003e2 MOA dot\u003cbr\u003e2 MOA dot + 65 MOA circle\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eVertical adjustment range\u003c\/td\u003e\n\n\u003ctd\u003e+\/- 50 MOA\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eHorizontal adjustment range\u003c\/td\u003e\n\n\u003ctd\u003e+\/- 50 MOA\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eClick value\u003c\/td\u003e\n\n\u003ctd\u003e0.5 MOA\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eBrightness adjustment levels\u003c\/td\u003e\n\n\u003ctd\u003e12\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003ePower\u003c\/td\u003e\n\n\u003ctd\u003eCR2032 battery\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eMaximum operating time\u003c\/td\u003e\n\n\u003ctd\u003eup to 50,000 hours\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\n\u003ctd\u003eTitanium\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eWater resistance rating\u003c\/td\u003e\n\n\u003ctd\u003eIPX8\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eVibration resistance\u003c\/td\u003e\n\n\u003ctd\u003e1000 G\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eOperating temperature range\u003c\/td\u003e\n\n\u003ctd\u003efrom -40°C to 60°C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eStorage temperature range\u003c\/td\u003e\n\n\u003ctd\u003efrom -40°C to 70°C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eViewport diameter\u003c\/td\u003e\n\n\u003ctd\u003e20 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\n\u003ctd\u003e68 x 37 x 41 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eWeight\u003c\/td\u003e\n\n\u003ctd\u003e123 g\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003ctr\u003e\n\n\u003ctd\u003eColor\u003c\/td\u003e\n\n\u003ctd\u003eBlack\u003c\/td\u003e\n\n\n\u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"Holosun","offers":[{"title":"Default Title","offer_id":58518576955776,"sku":"1000004263509","price":608.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/3596\/7872\/files\/42635_3.jpg?v=1787435688","url":"https:\/\/sectordefence.com\/en\/products\/holosun-enclosed-collimator-he515gt-titanium-killflash-qd-picatinny-flipback-he515gt-rd","provider":"sector defence","version":"1.0","type":"link"}
