Love this sight - TROY HK Folding Tritium BattleSight

Has a robust mechanical feel when flipping up. Target acquisition when looking through this sight is excellent. Great for older shooters whose eyesight is not as good as it used to be. Takes up minimum space on the pic rail when folded. I like that they copied the HK style as it is a very successful design. Heck, they even copied the hefty HK price tag too. This is a great sight for those like me who intend to use iron sights on a regular basis. I would recommend getting the matching rear sight as I made the mistake of buying a cheap rear sight and ended up reducing the effectiveness of this wonderful front sight. Definitely worth the money.
