The Ares Red Dot comes with a custom optical system with minimal power draw and Shake Awake motion sensing technology. The dot will automatically shut off after one hour and re-activate instantly upon movement, providing tens of thousands of hours of battery life on a single battery, up to 10 times longer than LED powered red dots. Comes with a parallax free circle cross reticle with a 2 MOA center dot. Electronically controlled illumination with multiple levels of intensity up to daylight bright. Integrated picatinny recoil lugs compatible with picatinny mounting platforms, built to withstand both large caliber rifle and shotgun recoil.
