Holosun ELITE enclosed Reflex Red Dot Sight HE512T-RD with switchable reticle and titanium housing
Holosun HE512T-RD Red Dot Sight: Advanced Performance for Tactical and Sporting Demands
Engineered for shooters who expect precision and reliability under pressure, the Holosun HE512T-RD brings a new level of versatility to the red dot category. Unlike its green-dot counterpart, the HE512T-RD leverages Holosun’s signature red Super LED technology, offering a classic aiming solution that excels in both bright sunlight and low-light scenarios. This sight is built for those who move between dynamic environments—whether that’s hunting in unpredictable weather, competing in action shooting sports, or leading tactical teams.
Distinctive Features and Technology
- Titanium Enclosure:
The HE512T-RD’s housing is machined from Grade 5 titanium, providing a rare combination of lightweight handling and exceptional resistance to impact, corrosion, and harsh field conditions. - Red Super LED System:
The sight’s high-efficiency red diode delivers a crisp, daylight-bright reticle with minimal battery draw. This makes it ideal for shooters who prefer the traditional red dot’s visibility and contrast, especially when engaging targets at speed. - Multiple Reticle Selection (MRS):
Instantly switch between a precise 2 MOA dot, a bold 65 MOA circle, or a combined circle-dot reticle. This flexibility suits both fast target acquisition and precision work at distance, without the need for re-zeroing. - Dual Power with Solar Failsafe™:
The integrated solar panel automatically powers the sight in strong light, seamlessly switching to the CR2032 battery when needed. This redundancy ensures your reticle is always on, even during extended sessions or unexpected battery depletion. - Shake Awake™ Motion Sensor:
The optic automatically enters sleep mode when stationary and wakes up the moment you move your firearm, preserving battery life and guaranteeing readiness. - User-Oriented Controls:
Large, tactile buttons and a side-loading battery tray enable easy adjustments and battery changes, even in the field or while wearing gloves.
