Shake Awake
Another great piece of technology created by Holosun is Shake Awake™. This great feature allows an optic to automatically go to sleep when the unit has not detected any type of movement or vibration in a specific amount of time that is programmable by the operator. However, once the unit senses movement, it will automatically turn itself on and recall the last brightness that was used. This great feature helps promote battery life further and insures the unit is on and ready when you need it!

Super Green LED
Holosun has been a leader in laser and LED technology for many years. The new Super Green LED is our latest advancement in this field. We have created a new green diode allowing it to be as much as 4 times efficient than our standard red diode. Not only does the Super Green LED give the user an option for those who have difficulty seeing in the red color spectrum, but it also gives greater power efficiency when using the optic in high brightness settings.

  1. Billy Clifton (verified owner)

    Kenzie’s is an awesome company to deal with. Customer service is outstanding. I was sent a defective Holosun 403 and they fixed the problem and had a new one sent out and delivered earlier than expected. The new 403 I received works flawlessly. Thank you!
