A compact solution for people who spend long hours outdoors due to their profession or love for hunting. Compatible with most standard mounts, pistols, shotguns, air rifles, and crossbows, you can pair it with any of these firearms.

Equipped with a CR2032 battery, LED lights, and shake awake technology, the micro sight will not let you down in the field, as it can operate for 50,000 hours on a single battery and will turn off automatically when not in use.

A product of Holosun Technologies, this optic features 2 MOA red dot size, decreased training time and ammo, an unlimited field of view, and parallax-free with unlimited eye relief. Its waterproof and shock-resistant quality ensures your optic remains operational under extreme weather conditions. You can also operate it during the day and night due to the 10 daylight and 2-night vision brightness level settings it offers.

When you order this optic, you will also receive a low mount and 1/3 co-witness mount. To improve durability and longevity, the manufacturers have designed it using 6061 aluminum. If you are searching for an optic you can depend on for years, you are looking for the micro sight. It is easy to install and use with your firearm.

The 403GL is a small compact red dot sight with side battery housing and H/L adjusting turret options. Employing Holosun’s LED technology, the lifetime for one CR2032 battery can be up to 5 years. 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.
