First the size of 2 MOA in relation to the threat when viewed is a non-issue. The multiple brightness settings of the CompM3 and CompM4 allow you to adjust the brightness/size of the dot based on your needs.
The performance of the CompM4/M3 is optimized for use with all generations of night vision devices (NVDs), but is especially suited for 3rd generation night vision technology. Aimpoint’s unique band-pass coating on the front lens reflects select frequencies of red light at near 100% efficiency in order to give the highest possible dot brightness with the smallest amount of energy while transmitting nearly 100% of light in the Infrared and near-infrared part of the spectrum to provide the clearest, brightest image possible when used with a 3rd generation NVD.
Some things that needs to be considered when purchasing a combat optic that you’ll trust with your life is durability, reliability, simplicity, and life cycle costs. The intent is not to create a debate about which optic is the best but to compare life cycle costs of combat optics based on Apples and Apples as best possible, thus I used only the data provided by each manufacturer for their optics that are NVD compatible for military use, GRTactical retail price (where possible), as well as an approximate battery cost based on a Google search. I used 80,000 hours as that is life of a CompM4 constantly on at setting 7.
