According to the manufacturer there is a limited two year warranty on the ATN PVS14-3 Generation 3 Night Vision Monocular. I recommend contacting the manufacturer regarding the specifics of their warranty.
The manufacturer recommends using the ATN PVS14-3 Generation 3 Night Vision Monocular with a red dot sight or a laser aiming device but not a magnified optic.
You would mount the ATN PVS14-3 Generation 3 Night Vision Monocular behind a scope, but I would recommend using a non magnified red dot if you are going to.
In optimal conditions with a quality IR illuminator typically a gen 3 night vision will max out at around 300 yards, also keep in mind there is no magnification with this monocular.
Yes this comes with both a helmet mount and a head mount.
