Eliminate the hassle of manually turning on your optic device by ordering the elite micro sight, featuring the Shake Awake technology. Just give your optic a slight shake and it will turn on. When no movement is detected, it will turn off automatically, thus conserving power.

In addition to this, this optic features a new green LED technology 65 MOA green circle dot with the option to switch to the 2 MOA dot and CR2032 battery, allowing it to operate for 50,000 hours and five years. The “U” indicates the location of the battery, which is on its side whereas the “G” indicates the location of the windage and elevation turrets, which is located on two sides.

Featuring 10 daylight settings and 2 NV brightness settings, you can operate the optic during the day and night. Its IP67 rating and shockproof ability allow you to use the optic with your weapon regardless of the weather conditions.

You can equip it with crossbows, shotguns, pistols, air rifles, and standard mounts. To ensure longevity and durability, the manufacturers have designed it using 6061 aluminum. Some notable features include an unlimited field of view, 1x magnification, parallax-free with unlimited eye relief, reduced training time and ammo, and lots more.

The HE503GU-GR Elite is a new micro green dot optic equipped with a 65 MOA circle dot reticle with the option of switching to a 2MOA dot only. The “G” signifies that the battery is side-mounted on the side of the optic. The “U” signifies a housing design that shrouds the windage and elevation turrets on two sides. Employing new green LED technology, the life-time for one CR2032 battery can reach 5 years on the 2 MOA dot. Holosun’s “Shake Awake” technology automatically turns the optic on at the slightest movement. When the optic senses no movement, it will go to sleep.
