The Holosun HS510C & HM3X Combo pairs an open reflex red dot sight with a 3× magnifier, offering added versatility for close- and mid-range applications. This combination provides the flexibility to switch between an unmagnified and magnified sight picture quickly and easily.

The HS510C incorporates Holosun’s Solar Failsafe technology, featuring an integrated solar panel that monitors available ambient light and automatically adjusts reticle brightness. Under adequate lighting conditions, the sight can operate primarily on solar power, while battery power seamlessly takes over as lighting conditions change. This dual-power system helps maintain consistent operation, even if the battery becomes weak or depleted, provided sufficient ambient light is available.

The HM3X magnifier features a convenient side-flip design, allowing users to transition between 1× and 3× magnification as needed. An adjustable diopter provides customized focus, helping deliver a clear sight picture based on individual eyesight.
