The Holosun HE515GTGR is engineered as a robust 20mm micro green dot sight, purpose-built for demanding rifle and carbine platforms. Its construction from Grade 5 titanium ensures exceptional resilience across diverse operational environments, establishing it as a critical component in advanced tactical optics configurations.
Key Features
Grade 5 Titanium Housing
The optic features a housing precision-machined from Grade 5 titanium. This material selection provides superior durability and impact resistance, ensuring zero retention under rigorous field use and mitigating potential damage from concussive forces.
Multi-Reticle System (MRS)
The integrated Multi-Reticle System (MRS) offers operational flexibility with a crisp 2 MOA Green Dot or a 65 MOA Circle reticle, both projected by a Green Super LED. This capability allows operators to select the optimal reticle configuration for specific engagement distances and target profiles.
Advanced Power Management
Power efficiency is managed through a comprehensive system incorporating Holosun’s Solar Failsafe technology, enabling autonomous operation via ambient light, and Shake Awake technology, which conserves battery life. This system contributes to an operational runtime of up to 50,000 hours on a single CR2032 battery. The side-mounted battery tray facilitates tool-less replacement for rapid field maintenance.
Environmental Resilience
The HE515GTGR carries an IP68 certification, confirming its waterproof and dustproof integrity. This rating ensures consistent operational performance in adverse weather conditions and challenging environmental settings, from precipitation to particulate exposure.
Integrated Mounting and Protection
Included with the optic are integrated clear, removable, and rotating lens caps for objective and ocular lens protection. The unit is supplied with a Quick Detach (QD) absolute co-witness (1.41″) mount, facilitating rapid integration and deployment on Picatinny rail systems.
