Excellent front sight post - Meprolight M16/AR15/A1 Front Sight

A very inexpensive upgrade to any AR. The sight post provides a very visible aiming point at night without the use of batteries. Even if you have night vision equipment, at some point you will run out of a way to power them. When that happens, having an alternative in place and ready to use is a win win. Back in the day (M16A1) the tritium front sight left a bit to be desired in that you either had to be one click high or low on your zero and then had to black out the opposing side to prevent observation from down range. Meprolight has fixed all of that. The part of the post that contains the tritium rotates on the base so that once you get a good zero you depress the detent and rotate the tritium dot into view. And if it cause's a distraction while wearing NVD rotate it one click out of the way and drive on until you need it. I really do like this front sight post and recommend it to everyone.
