Ibex Armament


Holosun Technologies 510C (Red)


Availability: In stock

If you lived in New Mexico and this was a breakfast burrito, the server would ask you red or green, referring to your sauce choice, not dot color. If you were a professional you’d answer, “Christmas.” Go ahead, order both the red and the green.

The HS510C is an open reflex optical sight designed for rifle and carbine applications. Features include Holosun’s Super LED with up to 50k hours battery life, Multi-Reticle System, Solar Failsafe, and Shake Awake. The optic has an open frame for a wide sight picture. It is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.

The box comes with your absolute co-witness QD mount, T10 L Key for mounting, a user manual (if you can read), CR2032 battery, and a lens cloth.

    I bought this optic for an amazing price on Jan 23 and had it in my hands on the 31st, excellent shipping times. The item came in perfect shape and had a hand written note from the website owner. It put a smile on my face. Can’t reccomend this seller enough! The optic itself works amazing and I’m very happy with it. Was a quick 1 minute install. I look forward to ordering from Ibex in the future.

    Ordered on 1/23 for a great price, and received on 2/1 in excellent condition. This is the second 510C that I have purchased, but the first time buying from Ibex. There was a hand written note from the owner as well as a note on the brown paper wrapping covering the Holosun box. I’ll spend more money at Ibex in the future.
