Holosun HE515CT-GR 20mm MRS Green Solar Titanium Red Dot Sight
The Holosun HE515CT-GR is a 20mm micro red dot sight engineered for demanding tactical and competitive applications. This compact optical solution provides a precise aiming point across a range of firearm platforms, optimizing target acquisition speed for experienced shooters in sport, defense, or professional contexts. Its robust design integrates several critical performance features, leveraging advanced materials and power management technologies to ensure reliability in the field.
Key Features
Multi-Reticle System (MRS)
The MRS offers user-selectable reticle options to adapt to varying operational requirements. Users can select between a precise 2 MOA dot for enhanced long-range accuracy or a 65 MOA circle-dot reticle for rapid close-quarters target acquisition. This versatility supports accurate target engagement whether deployed on a precision rifle or a carbine used for personal defense.
Solar Fail-Safe Technology
This integrated power management system utilizes ambient light to power the reticle, enabling operation without primary battery draw in suitable lighting conditions. In conjunction with highly efficient LEDs, the CR2032 battery provides an extended operational life of up to 50,000 hours (approximately 5 years), ensuring sustained readiness.
Titanium Housing
The optic is constructed with a CNC-machined titanium housing, providing exceptional structural integrity and resistance to extreme environmental and operational stresses. This material selection ensures consistent performance and reliability under harsh field conditions, making it a robust choice for mission-critical optics.
Shake Awake Technology
To conserve battery power without compromising readiness, this system automatically enters a sleep mode during periods of motionlessness. Upon detecting movement, the reticle instantly reactivates to its last used brightness setting, mitigating activation delays.
Integrated Accessories
The HE515CT-GR includes removable, non-obstructing, clear flip-up lens covers for immediate optical protection against debris and impacts. Additionally, an anti-reflection kill flash is integrated, effectively reducing glare and minimizing the visible signature of the reticle to observers downrange.
