Holosun HS403B 20mm Micro Red Dot Sight with 2 MOA Dot
The Holosun HS403B is a compact 20mm micro red dot built for rifle and carbine use, featuring a crisp 2 MOA dot reticle and 12 brightness settings (10 daylight and 2 night-vision compatible). Shake Awake technology helps extend runtime by powering the LED down when the optic is motionless.
This optic uses a CR2032 battery in a side-mounted tray and is fitted with a Picatinny/Weaver mount.
