Our sights offer a quick target acquisition by using a dot over dot pattern like the number 8 using a 6 o' clock hold. Easily adjust your sights for windage by lessening the set screws. T.A.S sights are meant to be used with both eyes open, just like you would with an electronic red dot sight. All T.A.S TJ sights are designed for fast target acquisition, greater accuracy, low profile and a very simple installation process.
