Troy Industries’ Tritium BattleSights™ are designed to eliminate the poor sight orientation that is typical in twilight. Tritium is a form of hydrogen that emits a continuous light source when batteries or electricity are not available. The front post is centered between two Tritium points of reference to allow proper alignment.
Durability and dead-on accuracy make Troy BattleSights the hands-down first choice of Special Ops and Tactical Users Worldwide. Troy’s M4 Front Folding BattleSight is easy to install and deploy, with no levers or springs to fumble with. No tools required for adjustment.
Troy Tritium M4 Front Folding Sight
Overall the sights are very well built, but for the price I paid I was really hoping the tritium would be a little bit easier to pick up on when looking down range. It’s worth noting that the trium is only on one side of the 4 sided front sight post, so you better hope it aligns with your zero. I’m also slightly disappointed that the sights do not flip up with assist from a spring. They are built like tanks and I have no doubt they will serve me well, but I would hope that if Troy were to look to enhance the features down the road they would consider enlarging the tritium and adding a spring assisted opening mechanism.
