The HE407K-GR X2 Green Dot Reflex Sight improves on previous the version by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.
Additional features include Holosun’s Green Super LED with up to 50k hour battery life, a crisp 6MOA dot, and Shake Awake.
