Would not recommend - Bushnell 2X28mm Digital Sentry NV Monocular Weapon Helmet Mount

I removed it from the box and I was pleased with the robust construction. Heavy plastic gives the appearance of durability. Using it in daylight the objective lens Focus brought the viewer into Crystal clarity. Unfortunately night View is where this little scope falls down. The IR illuminator is not aligned to the bore sight of the scope. It is underpowered and aims to the right of line of sight making it useless at anything over 50 ft. I used the scope on a dark night with cloud cover and without the illuminator it has no visibility whatsoever Outdoors. While the construction appeared solid , the attachment nut is shallow and of light metal. The mounting screw would not tighten on the scope, leaving the scope loose and sloppy . My experience with night vision is 30 years old, I used Generation 1 equipment in the military and was expecting this scope to be an approximate equivalent. It falls far short. I would not buy it again.
