We started by improving the optical configurations which lowered the F-stop factor and increased optical resolution. By doing this, more light travels through the lens to the tube. More light and better resolution simply means brighter and sharper image.
Then we added our precision "Red on Green" aiming system, easy push button operation, reticle brightness adjustment and our detachable most powerful in the industry 450 mW Infrared.
Windage and elevation adjustments are an amazing 1/4 inch at 100 yards. Our ATN Aries MK 390 Weapon Sight is the best 1st Generation scope on the market. The ATN Aries MK 390 easily mounts onto any U.S. standard 7/8" weaver or Picatinny rail.
