HOLOSUN 507K X2 – Multi Reticle

4 customer reviews



The HE507K 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 our 2018-2019 LE pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting 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 LED with up to 50k hours battery life, Multi-Reticle System, and Shake Awake.

    I have astigmatism and tried a red dot before getting this one and the dot was not so great to my eyes. I was told to get a green dot with a circle dot and it was the best desicion. Not only I can see it much better but it’s crisp and I can adjust manually to suit my eyes. Tacrig shipped my order very quickly and I got it in 5 days. Considering the order was made on a weekend I was very surprised to receive it so quick. I also got an excellent black Friday deal that beat all other places (and I looked everywhere)

    Love the green clear reticles on my Hellcat specifically since I have a very bad astigmatism
    My eyes easily pick up my point of aim so easy now. Can’t express enough how your products are the best in the market.

    Super fast shipment. Received shipment notification within 24hrs. I bought it to test out if it will help with my astigmatism. It somewhat did but this is my first 508T and so far i’m impressed with the product.
