THIS IS THE SCOPE! 1ST GENERATION DOES NOT GET ANY BETTER THAN THE ARIES 390 PALADIN. WE SET OUT TO DESIGN THE BEST 1ST GEN SCOPE ON THE MARKET AND WE SUCCEEDED. 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 new detachable, most powerful in the industry 450mw Infrared Illuminator with dedicated windage and elevation adjustments. Our new Aries 390 Paladin is the best 1st. generation scope on the market
