The Holosun 407K X2 is an open reflex optical sight designed for concealed carry pistol applications. Features include Holosun’s Super LED (green or red) with up to 50k hours battery life, 6 MOA dot only, and Shake Awake. The X2 Series pistol optics feature two improvements. First is the addition of Lock Mode from Holosun’s 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.
