Surefire X300U-B Ultra WeaponLight T-Slot Thumbscrew Clamp
The powerful, virtually indestructible X300 Ultra WeaponLight was primarily designed for handguns but is also excellent for long guns and mounts securely to MIL-STD 1913 rail-equipped rifles via its newly enhanced T-slot mounting system. This top-selling WeaponLight features a high-performance LED that generates 1,000 lumens of stunning white light that’s focused by a Total Internal Reflection (TIR) lens to produce a high-intensity beam with extended range yet it provides significant surround light for peripheral vision in close quarters. The highly efficient virtually failure-proof LED generates tactical-level light—ideal for close- to long-range target identification—for 1.5 hours per set of batteries.
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. Optional DG grip switches (for handguns) and pressure-activated XT tape switches (for long guns) permit the X300 Ultra to be activated remotely.
The X300U-B can be securely attached to a handgun or a long gun via its new mounting system which incorporates a tightening screw and a T-slot mounting rail. Universal and Picatinny crossbar wedges are included for simple, foolproof installation. Its high-strength aerospace aluminum body—including the mounting system—is Mil-Spec hard anodized for superior toughness and its O-ring and gasket sealed to keep out dust and moisture.
FITS: The new T-slot mounting system fits most railed handguns (and rail-equipped long guns) but adapter mounts are available for some non-railed handguns.

Excellent, pro-grade light. Very pleased. FYI, I used the "universal" (U) cross-beam adapter instead of the picatinny (P) adapter on my Glock G19 even though it has Picatinny rail mount. Checked with Surefire, and it is correct. Fits perfectly snug.
Simple to install, works great!
I'd stake my life on Surefire products. This weapon light is what I expect from Surefire. The best money can buy, and thanks to Botach it wasn't that much money. Worth every penny.
Another Excellent product from Surefire. When you want Quality choose Surefire......
This light is awesome! Super easy to put on and take off if you want to change it up. Very bright. Best price I've seen anywhere.
Excellent light and excellent place to purchase it from!
I could go on at length about the many reasons I adore the new X300-B; however, I'd, presumably, be telling everyone what they already know. If you want quality, you pay for quality. End of story.
excellent fit and finish and exactly what I was looking for
A great sure fire product but the switch on the cap is too tight.
