Meprolight AR-15, M-16A1 & A2 Tru-Dot Night Sight. Front sight only

The ML31615 is a front sight only for use on AR style A1 and 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 you have the rifle sighted in for a particular distance, should the tritium light source not be facing you, all you do is depress the detent and rotate the sight to align the light source. MEPROLIGHT sights, like our other self-illuminated products & devices take maximum advantage of tritium light sources - the fail-safe, maintenance-free light sources that don€t require any external source of energy and provides up to 15 years of usable light under all weather conditions. MEPROLIGHT continues to offer the strongest guarantee in the industry for the usable light of our TRU-DOT sights.
