Holosun - Enclosed Red Dot Sight HS515GM - Multi Reticle - Black - HS515GM

The Holosun HS515GM is a closed-body red dot sight designed for use in demanding conditions—from humid forests to sandy firing ranges. Thanks to its compact design, the sight’s weight is barely noticeable on the firearm, yet the device still offers very high mechanical durability. Minimized parallax is virtually undetectable during use, making the HS515GM an excellent choice for dynamic shooters.

Shake Awake Technology – Energy Saving and Instant Readiness

In situations requiring an immediate response, every second counts. The HS515GM red dot sight is equipped with an intelligent Shake Awake system that eliminates the need to manually turn on the sight. Upon detecting inactivity, the device automatically enters sleep mode, conserving energy.

The collimator wakes up immediately upon detecting the slightest movement, restoring the last-used settings. Thanks to this solution and an energy-efficient LED, a single CR2032 battery provides up to 50,000 hours of operation, which translates to years of use without needing to replace the battery.

MRS System – Full Control Over the Reticle

The HS515GM red dot sight is equipped with the Multi-Reticle System. This allows the user to choose between three red reticle display modes without having to re-zero the device.

The 2 MOA dot ensures precision at long range, the 65 MOA circle facilitates instinctive aiming at close quarters, and the dot + circle combination combines these two features. 12 brightness levels, including 4 modes for use with night vision, guarantee the reticle’s visibility in various lighting conditions.

Uncompromising durability—high waterproof rating and rugged materials

The HS515GM model stands out from the competition thanks to its use of 7075 T6 aircraft-grade aluminum. This material is significantly harder than standard alloys, which, combined with shock resistance up to 1000 G, makes the collimator an exceptionally durable design. The sealed housing, meeting IPX8 waterproofing standards, protects the emitter from damage even after the device is fully submerged in water.

Quick installation and compatibility with magnifiers

The red dot sight comes with a Picatinny rail mount equipped with a Quick Detach lever. This allows for instant removal or attachment of the sight without tools, which is essential for frequent changes in weapon configuration. The HS515GM model features integrated lens covers and a removable honeycomb filter that eliminates light reflections that could reveal the shooter’s position.

The 41 mm mounting height (Lower 1/3 Co-witness) was selected to ensure compatibility with Holosun red dot sight magnifiers, such as the HM3X or HM6X. With this model, the standard Lower 1/3 Co-witness height allows for the use of mechanical sights, visible through a window in the lower part of the red dot sight mount, without the need to remove it.
