Holosun HE512T-RD Red Dot Sight Red Reticle

Built for hard-use long guns, the Holosun HE512T is an open reflex red dot sight that delivers a fast, confident sight picture while standing up to real field abuse. Its Grade 5 titanium housing keeps weight to 9.17 oz yet provides exceptional strength and corrosion resistance for duty, training, and harsh environments.

The large 0.91 x 1.26 in window helps you track targets quickly, while Holosun’s Multi-Reticle System lets you switch between a crisp 2 MOA dot and a 65 MOA circle-dot for speed up close and precision at distance. Solar Failsafe keeps the reticle running when light is available, and Shake Awake extends runtime by powering down when the optic is idle—backed by up to 50,000 hours on a CR2032 battery. Dial in zero with 0.5 MOA clicks and a generous ±50 MOA windage/elevation range.

The HE512T-RD is at home on carbines, PCCs, and shotguns, and includes an absolute co-witness mount (1.41” dot height) for a straightforward setup with iron sights. IPX8 submersion rating and a -30℃ to 60℃ operating range reinforce Holosun’s reputation for optics engineered for professional use.
