Holosun Technologies 407K-GR X2 (Green)


Availability: In stock

We won’t talk in circles. The 407K and 507K are fairly similar, except 407K models feature only a dot, no circle reticle surrounding the dot. The green model, as seen here, might be better for your astigmatism if you have it.

The HE407K-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 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 Green LED with up to 50k hours battery life, and Shake Awake.
