Surefire X300 Ultra
The Surefire X300U is one of the most widely-issued weapon lights in special operations and law enforcement units. And for good reason. It boasts an impressive track record, is nearly indestructible, and has improved with the times at a steady pace. With SureFire’s recent upgrade to the light, the current X300U-B outputs 1000 lumens on two CR123A batteries for a tactical run time of 1.25 hours. The beam is tight with a focused center and spill on the edges. This means the light can be used at distance very nicely. We highly recommend the X300 series of lights at T.REX ARMS.

Activating the X300 Ultra is done via intuitive, ambidextrous switches—now wider and shorter for improved ergonomics—at the rear of the body. Simply press the switch on either side for momentary-on activation or flip up or down for constant-on activation.
The X300 Ultra is compromised of two models, the “A” and “B”. These signify the attachment system of the light. The A model features Surefire’s Rail-Lock system, a latch attachment. You pull down on the two levers on the side of the light and slide the X300 onto the rail system. It will then lock in place. The B model has a T-slot mounting solution that is tightened by hand, and then turned a half rotation with a flathead screw driver, bullet casing, knife, etc.
