ATN® PS40 - 2 Day / Night System enhances your scope with 2nd Gen. night vision capability.
The PS40-2 mounts in front of your daytime scope, allowing you to convert your scope into a high quality, very accurate night vision weapon sight. This ingenious setup lets you go from day to night in less then 30 seconds without tools or changes in eye relief, all while remaining zeroed-in around the clock.
The PS40-2 is a complex optical-electronic system with the latest 2nd Gen. image intensifier tube technology... the same technology law enforcement and tactical operators rely on for serious night imaging. It fits scopes from 47 mm to 58.7 mm, and each PS40 unit is individually tested and aligned on an optical scale to provide pinpoint-perfect alignment.Specifications:
