Decent product for the $$ - Sightmark Photon Digital Night Vision Rifle Scope

The scope works well in daylight with the included shade-cap. At nighttime the scope (as per its digital roots) will need some light, either a 3/4 to full moon, or you turn on the IR. The scope under both conditions will require some turning of the contrast control to get a clear picture.

As per the earlier reviewer, I also installed this on an AR and was getting 2" groups at 50 years with the red dot covering the 4" black circle on my paper target.

As a minor complaint, the unit can turn on relatively easily if the contrast control is rotated at all, which will then run the 2xAA batteries dry. My bigger issue with the scope is the shade-cap comes off far to easily, so that moving around with it on during the day is not advisable unless you run a strip of electrical tape around its edge to fully secure it to the scope. On one occasion I had to backtrack 200 yards down a path in the middle of the day trying to locate it, after it just dropped of the scope.

I also purchased the Sightmark CVR640 Digital Video Recorder which works with the Photon and Pulsar series of scopes. My review of this item for the high price that it costs, is not as glowing as the Photon scope. I would rate it 2 out of 5 stars, as its buttons are a bit finicky, build quality just seems cheap, a decent rain shower would likely destroy its internals (not waterproof), and its small LED's that indicate if its on and recording are just too small.
