The SureFire X300U-B Tan Weapon Light (SureFire part no. X300U-B-TN) is the thumbscrew-clamp version of the X300 in a tan finish, producing 1,000 lumens. A T-slot thumbscrew clamp attaches it securely to the Universal and Picatinny rails found on most handguns. A custom TIR lens makes a smooth, far-reaching beam with a larger center spot and surround light, which works for close- to medium-range engagements. Integral ambidextrous switching gives instant activation without changing your grip. Operators in law enforcement and the military have trusted the X300 family for years.
