C-More 8 MOA Dot Module for Polymer SightC MORE Systems red dot sights encapsulate the light source in a separate diode module. These modules are interchangeable in all C MORE full size sights (NOT STS or RTS2), providing each sight with the ability to utilize different size dots for different applications. They also produce super efficient current consumption which extends battery life to 300 1500 hours of continuous use from a single 3 volt lithium battery. C MORE Systems red dot sights
