Holosun HE515CT Titanium 20mm Green Circle Dot Sight

Holosun HE515CT Elite Solar Titanium Sight is a 20mm micro red-dot style optic designed for rifle and carbine use. It provides a selectable 2 MOA green dot and a 65 MOA green circle reticle for close- to mid-range aiming references.

This sight addresses durable, low-profile aiming needs on modern sporting rifles and similar platforms. It combines a lightweight grade 5 titanium housing with Holosun’s Multi-Reticle System (MRS), allowing users to switch between a 2 MOA dot and a 65 MOA circle plus dot. Solar Failsafe and efficient LEDs extend usable operation, while Shake Awake preserves battery life. The optic is intended for use as a primary non-magnified sight on carbines, patrol rifles, and range setups.
