I see reviews of these sights where folks complain about them not being bright enough. Let your night vision acclimate and there will be no problem. You have to consider that if they were too bright they would deteriorate your night vision and risk giving away your Location . You will see much improved night shooting with these installed. A must have for serious work.
Pros: dependable, rugged, always on, lasts for years.
Cons: If you are not familiar with AR sight installation use a gun smith.
