Holosun HS403A Red Dot

This high powered scope no longer has a bump for the battery! The PARALOW HS403A Red Dot scope has no external battery housing: The battery is hidden in the base of this night vision optic where it is rarely needed to be changed. This elegant design allows this night hunting scope to be simply, a tube, allowing the maximum field of vision. This night optic provides the option for aiming with both eyes which is now just a reflex; allows you to have maximum situational awareness.  This night vision optic includes 50,000-hour battery life, is parallax free, and has a durable PEO/MAO finish.  Add to this an auto wake feature that automatically turns on the scope when it is moved and an adjustable 8-hour auto-shutoff and you know you have a powerful night vision optic.  This scope comes with two mounts, a low profile and an AR height lower 1/3 mount.
