In the world of tactical sights for the ar15, people often think of Trijicon sights, how ever I doubt many people think trijicon when reflex sights come to mind. You have eotech and a host of other red dot manufactures out there, and they have a great product, but trijicon does something they don’t, they don’t use batteries in some of there sights. The sight I’m looking at this week is the RX-30A reflex sight. This sight would be at home on any ar rifle and works well in both low light and bright conditions. For situations that demand a rugged optic that must last for an undetermined amount of time, the trijicon sights fit the bill. The tritium last years and is bright enough to be seen in any condition, for the operator, this means an effective sight, and you don’t have to worry about or carry batteries. The sight has a wide field of view and is very easy to get on target. If you’re looking for a tactical reflex sight for your rifle, consider the trijicon reflex as a rugged battery less option.
