XS Sight Systems XTI2 DXT Big Dot Sight 0.188 in Wide for AR-15. XTI2 sights reduce target engagement time and eliminate magnification adjustment. Our second generation XTIs feature taller bases for easy sight alignment without having to break a standard cheek weld. Additionally the base angle has been increased to accommodate wider lens optics. DXT Big Dot version features a tritium front sight that measures 0.188" wide and a straight-line tritium stripe express sight picture. XTI2 express sights are ideal for 3-gun competitions. XTI2 sight sets are mounted in front of the optic to reduce snagging gear on chest rigs. 3-gun matches cover distances from short to long distances. XTI2 sights are pistol sights designed for pistol length distances where magnified optics make target identification more difficult. XTI2 sights ship with thread locker and a front sight adjustment tool. The rear sight is installed but not sealed in place to allow for easy windage adjustment. Thread locker will need to be applied after the rifle is zeroed.
