The RMR Type 2 is designed with a patented housing shape that absorbs impacts and diverts stresses away from the lens to increase durability. It’s suitable for military, law enforcement, concealed carry self-defense, target shooting, and hunting applications. All RMR Type 2 Adjustable LED sights are compatible with night vision devices, with the 3.25 MOA dot size being the most popular. The 3.25 MOA dot is the most versatile and popular of all RMR dot sizes. The dot is small enough to allow accurate shooting at range while also being big enough to locate quickly.
