Great sight picture with a big dot - XS Sight Systems Big Dot Tritium Front for AR Mil-Spec

I mounted this sight post on a Troy hk style front sight and it works and looks great. Gives an excellent sight picture esp for CQB with the big white ring to put on the target, but without overwhelming your eye when making a precision shot. The tritium is bright enough to be seen well even in very low light but without any bloom in complete darkness. Highly recommend.
