With its enhanced field of view and clear, sharp red dot, the Trijicon SRO® (Specialized Reflex Optic) offers better pistol accuracy for target and competitive shooting applications. It is also designed to survive mistreatment both on and off the range thanks to Trijicon’s renowned toughness. In target and competition shooting applications, the large field of view and clear, sharp dot make it simple for users to locate and follow the dot, which enhances shooting accuracy and speed. There are two LED brightness modes available on every Trijicon SRO: automatic and manual. Furthermore, the CR2032 top-loading battery has a 3-year battery life (at setting 4 of 8).
