Holosun Technologies 507K-GR X2 (Green)

(10 customer reviews)


It’s screaming buy me. You just bought a new pistol and it’s naked isn’t it? These are the clothes you’re looking for.

Holosun’s 507K-GR-X2 is an open reflex optical sight designed for concealed carry pistol applications. The X2 Series pistol optics feature two improvements. First, is the addition of Lock Mode from the 2018-2019 law enforcement pistol optic models. When activated, Lock Mode locks the buttons preventing inadvertent settings changes. Second, the buttons have been redesigned to compliment the Lock Mode by placing them lower and out of the way. Additional features include Holosun’s Super Green LED with up to 50k hours battery life (on setting 6), Multi-Reticle System, and Shake Awake.

    Product looks great. Didn’t have a chance to mount it yet. But was able to play with the controls and check the reticle. Recital is crisp and clear, love the green sight, very easy to pick up. Shipping took some time, but hunter reached out and explained why. Don’t see that much these days. Will use purchase more products in the future.

    Best price I could get on this ANYWHERE so much that I actually waited a few weeks for it to be back in stock and he personally messaged me to let me know it was back. It also came with a hand written note thanking me for my order. Very personable

    Great optic, love the small footprint. Don’t really have any issues on it other than a very tiny nick in the middle of the glass. (Don’t see it unless your really focused on it close up.) Great seller, got the it delivered quick and great deal will recommend to anyone looking for an optic. 👍
