3 MOA Green Dot Reticle
The 3 MOA green dot reticle provides a distinct aiming point while maintaining a clean sight picture. Green reticles can be particularly noticeable in bright daylight conditions, making the Thrive HD a useful option for shooters who prefer a green dot sight over a conventional red dot.
The 11 brightness settings allow the reticle illumination to be adjusted according to the surrounding conditions. As with any green reticle, visibility can vary against backgrounds containing dense vegetation.

Shake Awake Technology and Battery Life
The ZeroTech Thrive HD uses a motion-sensing Shake Awake system to activate the optic when movement is detected. Auto Sleep helps conserve battery power when the sight is inactive, while Auto ON provides quick activation when the optic is moved.
A side-loading CR2032 battery makes replacement straightforward without requiring the sight to be removed from its mount. Maximum stated battery life is up to 50,000 hours, depending on brightness and operating conditions.
Low and High Mount Options
The Thrive HD Green Dot Reflex Sight is available with Low and High mounting configurations, providing flexibility when choosing the sight height for your setup.
The High See-Through Mount is designed to retain visibility of compatible iron sights beneath the optic, making it suitable for configurations where a co-witness or backup sighting system is required. The Low Mount provides a more compact sighting position where a lower mounting height is preferred.
Both configurations use a Picatinny-compatible interface.
Rugged ZeroTech Reflex Sight
Built for demanding shooting conditions, the Thrive HD is shockproof, waterproof and fog proof. Its compact body measures approximately 45mm in length and 28mm in height without the mount, with an approximate weight of 88g including the battery.
A moulded rubber cover is supplied to provide additional protection during storage and transport.
Clear Multi-Coated Optics
The Thrive HD uses multi-coated lenses with an anti-reflective (AR) coating designed to reduce glare and minimise image distortion. The 28mm x 20mm objective lens provides a clear sight picture through the compact reflex optic.
