Additional features include our MRS (Multi-Reticle System) with Super LED, 10 daylight and 2 night vision compatible reticle intensity settings, Shake Awake technology, and up to 50k hour battery life.

Granite Ridge's Take

The Holosun 515GM is a durable 20mm micro sight designed for rifle and carbine use. Its 7075 aluminum housing, removable lens caps, quick-detach lower-third mount and multi-reticle system make it a more feature-rich option than a basic micro red dot, especially for shooters building a hard-use or general-purpose rifle.
