Holosun Technologies HE510C-GR (Green) Flat Dark Earth


Availability: In stock

Green means go. FDE is Canadien for fuckin’ dope, eh?

The HE510C-GR Elite is Holosun’s flagship Open Reflex optic. Now equipped with Holosun’s highly efficient green reticle, the HE510C-GR Elite has an open frame for a wide sight picture. The HS510C Elite is powered by Holosun’s new, Advanced Super Solar Technology as well as, a CR2032 battery. Utilizing our multi-reticle system (MRS) this unit features three reticle choices. The HE510C-GR can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only, all at the push of a button. This optic is protected by a titanium-alloyed hood. And remember, the same emitter means no need for re-zeroing when switching which dot setup you’re using.

An absolute co-witness QD mount, T10 L key, user manual, CR2032 battery, and lens cloth all come in the box.

    this is my 2nd time ordering from here. I got a heartwarming handwritten letter thanking me! I felt loved. I will order 2 or more in the future. the prices can’t be beaten and if you find it anywhere else cheaper they promised they’ll beat it as they advertised. sorry I’m not good with words, but know that they are real caring people here! thanks a bunch
