Meprolight M22 Bullseye 3.5/40 MOA Red Dot Sight - Matte Black

The Meprolight M22 Bullseye is a self-illuminated reflex red dot sight engineered for 24/7/365 operation in any weather condition. Because it runs on a fiber-optic light collector by day and Swiss-made tritium vials at night, the M22 needs no batteries - it is always on and always ready the moment it is mounted.
