I have a the original ATN Ultra Sight, the one you manually control the reticle style and illum. settings. I prefer the manual over the digital because there has been some issues with the digital switching reticles during weapon cycling. However, I think ATN has solved the problem.
Overall, I think the Ultra Sight is great sight. Despite the optical glass looking vuneralbe to heavy use, it is quite stout and tough as all ATN products seem to be. For general use where magnificationis not required, it is a practical and inexpensive quality optical sight. For tatical use, I would not recommend it. Go with the more popular Eotech, ACOG's etc.
A few things that I am not pleased with(nothing major) are as follows:
-To use on the flat top AR platform you must do some modifications to your receiver rail to get you BUIS to fit behind the sight. Or mount the sight foward i.e. scout set up.
-You must remove your ATN sight off your weapon to change battery.
-Snow or bright days, I have problems using the sight effectively and must use BUIS.
-It is easy to forget to shut off unit. No push button on/off switch.
Other than these minor issues, it's perfect for hunting, plinking, low light situations where iron sights are not as effective. I have no problems maintaing field of view or using BUIS with fixed front sights.
ATN Scopes do not get all the good press they deserve, because of the spotty quality of it's Night Vision Products. Dollar for Dollar, I find ATN Daytime optics to be a great bargain with many features you will not find in many high dollar optics. Lifetime Warranty is as good as anybodys as long as you buy form an ATN authorized dealer.
