What Are Fiber-Optic Sights?
Adding a sight to your weapon is one of the most useful upgrades you can invest in. Sights increase your accuracy and shooting range in a number of ways. Fiber-optic sights pull this off by using an optical fiber that is transparent and flexible, often made of thin threads of plastic or glass about the size of a human hair. This optical fiber is able to transmit light along its fibers, making fiber-optic sights a great choice for a handgun or pistol.
