			<description><![CDATA[The Most Advanced DAY/NIGHT RIFLESCOPE SYSTEM IN THE WORLD. 

Superb Accuracy with Ultimate Features at Any Lux! 

The ATN 4-12X80 is a highly accurate daytime sniper scope. 80mm (!) objective and 40mm(!) tube combined with the best, German quality multicoated glass on the market makes this sight the best light-gathering device for shooting in the world.  
An array of features that will dazzle any marksmen include parallax-free construction; 4 to 12 variable Power Zoom, 1000-Yard Bullet drop Compensator with interchangeable cams for six calibers, 1000 Yard Range Finder and a super sharp, illuminated Reticle with 11 light settings. Additional features include 1/8 MOA adjustment at 100 yards, 100% weather resistance and Matte Black mil-spec finish with beryllium powder coating. 

To convert the ATN 4-12x80 to a Night Vision Weapon Sight all that needs to be done is a simple twist of the daytime riflescope eyepiece and replace it with a Night Vision eyepiece converting your scope into a high quality, very accurate night vision weapon sight.  

This ingenious setup allows the shooter in the field to go from day to night in less then 30 seconds without tools, without changes in eye relief and remain zeroed all around the clock. Furthermore the US government just granted ATN with a patent for the feature that prevents Tube burn by the illuminated reticle.
