The 403B is a small compact micro red dot optic. Employing Holosuns LED technology, the lifetime for one CR2032 battery can be up to 5 years. This optic features our Shake Awake technology that powers the optic on with slight movement of the 403B. It may be installed on various firearms such as shotguns, pistols ,air rifles and crossbows. The HS403B is compatible with standard mounts.

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!

"This sight is amazing, I have owned mine for over 5 months and have not needed to change the battery, it lasts for ever.

Pros
Runs easily available batteries
long battery life
Great price for an amazing red dot
dot is clear
easy windage and elevation adjustments, no screwdriver needed just use the cap
Comes with riser for hard lower face masks
Changes intensity based on inside or outside

Cons
uses a tiny torx screw to secure battery
uses torx for securing to picatinny

Other than that this sight is amazing
