The RMR is designed with a patented housing shape that absorbs impacts and diverts stresses away from the lens to increase durability. It also offers redesigned and upgraded electronics that have been proven to perform when mounted on slide ride pistols and other small arms. It's suitable for military, law enforcement, concealed carry self-defense, target shooting, and hunting applications. All RMR Adjustable LED sights are compatible with night vision devices, with the 3.25 MOA dot size being the most popular.Specifications and Features: CR2032 Battery 2ea #6-32 x1/2" Torx Head Screw 2ea #6-32 x .380" Torx Head Screw Hex Wrench RMR Manual Trijicon Sticker (PR15) Warranty Card RMR Sealing Plate (RM63)
