description Representing the latest advancement in Night Vision optics, the ATN PS40-4 gives your Daytime Scope Night Vision capability in a matter of seconds. The ATN PS40-4 mounts in front of a Daytime Scope to enable nighttime operation. No shift of impact, no need to rezero nor change of eye relief occurs. The ATN PS40-4 uses the latest in image intensifier tube technology for outstanding resolution and performance. Precision optical alignment is essential for a Front Sight System to work properly. This is why each ATN PS40-4 is individually tested and aligned on an optical scale by our engineers to provide perfect alignment. The ATN PS40-4 is one of the most compact and lightweight NV systems in its class, at only 840 grams.
