Holosun Technologies 509T-GR-X2 (Green)

(4 customer reviews)


Green is Great.

The Holosun 509T Elite Green Dot Sight uses both Solar Failsafe technology and a high capacity lithium battery to power the optic, ensuring you’ll always have a reliable point of aim while out in the field. These optics are designed with Shake Awake technology that senses motion to power the sight on and off, and last setting recall ensures you don’t lose your customized options once the unit powers down. This model offers up to 50,000 hours of battery life. Holosun’s Multi-Reticle System (MRS) gives the option of a 2MOA dot only, 32MOA ring only or ring with dot reticle. All versions are projected from the same LED, so no re-zeroing is needed when changing reticles.

The Holosun HE509T Elite Green Dot Sight provides a large field of view paired with useful features that will help you stay on target while greatly reducing target acquisition time. In addition, the fully enclosed housing provides enhanced environmental protection and shock protection that cannot be found in an open reflex form factor.

    The HE509T X2 GR is a great sight for the money. Wish the adapter plate was lighter, it’s a bit heavy since it’s steel, but aluminum replacements can be found. The optic is parallax free and not distorted at all. The image is bright and quick to pick up. A+

    I’m very happy with my order from Ibex armament. I’m usually a little skeptical of online sites but it came with good word from gun deals on reddit and a quick google check showed that there was no issues. They have excellent prices, email them to see how good they can do on any of their products. The RDS i got was a holosun 509Tg x2. I’m happy with the quality and i have no doubts of authenticity. I’ll be putting it through it’s paces soon. I’ll buy from ibex again.
