Meprolight ML31615 Green Front Night Sight for AR15, M16, A1, A2 Rifles. This sight has a round front post, which is much narrower than the square post currently coming on the AR rifles. This thinner post gives more accuracy since it does not cover as great an area of the target at distances. The ML31615 front sights is two-piece for alignment. Once the rifle sighted in for a particular distance, should the tritium light source not be facing you, depress the detent and rotate the sight to align the light source.
