Gun set sight for Smith & Wesson M&P Model - MEPROLIGHT

It really "shines" when other viewpoints are useless. No switch to turn on, no batteries to wear out. Both front and rear blades have their own green light source tritium gas and provide a green / green, 3-dot sight image. Some models is also available in yellow / green and green / orange. The front sight is always green in contrast to the rear sight. Unaltered by time, gun solvents or oils. Used by NATO, the United States and the Israeli armies. Also ideal for law enforcement and others that require precision in low light conditions. Contains both front and rear sight. Rear sight or replacement of the original rear completely or, like the S & W revolver, a new rear leaf, screw and nut are provided. Viewfinder or replacement of the original (1911 automatic); slip over and are stuck to the original blade (most other cars); or replace the factory colored insert (Autos S & W). Factory warranty on TRU-DOT places to the original purchaser for 12 years.
