The Truglo Tritium/Fiber Brite Site Handgun Sight - Ruger LC Front/Rear Green is made for the Ruger line of handguns, and it features the latest in technology. Fiber optics are used to find targets in brighter light conditions, while Tritium technology will find your target in low to no light conditions, and both do the job without the target knowing they are being sighted. It is made tough to last from rugged CNC-machined steel, and it requires no batteries. The snag-resistant design makes it compatible with most standard holsters.
