Most Helpful Positive Review Awesome light
Obviously there is a little sticker shock with this light. However, once you see the quality construction and the power in this light, justifying the price becomes easier. I got the “B” model and I do like the thumb screw. It allows for just enough retention.
Most Helpful Negative Review Works great but color is way off.
This light fits nicely and works great. However, I ordered the tan color to somewhat match the FDE on my FN FNX Tactical. The light is not tan, it is more gray and doesn't look right at all. I do not recommend the tan color as it seems whoever it is at Surefire in charge of colors must be color blin...

X300U-B, used box, stiff controls, cheap weight.

by Henny, Verified Owner from NC, United States Written on September 15, 2025
$300+ for a used product package, missing screw, and the on/off/momentary switch is stuck, takes 3x a trigger pull to manipulate it. I’ve been wanting an X300 variant for a year now and finally “pulled the trigger”, the box arrived obviously previously opened, the selector switch takes 10psi to move, and no such thing as momentary/strobe. 1/10 what I expected.

The “Go To” WML

by CG, Verified Owner from NJ, United States Written on February 4, 2025
I got my SureFire X300U-B as a weapon mounted light for my HK Mk23. It works and SureFire is known as a good light. However, I believe many of their competitors are catching up at a fraction of the cost of a SureFire. I had one issue with the battery lid in that one of the tabs came broken in delivery. I emailed Surefire’s customer support and there hasn’t been an answer in about a week. Replacement caps are $40. I guess I was expecting everything to be perfect out of the box. I’ll be going to Streamlight from now on.
Pros:
  • None
Cons:
  • Poor customer service
Best Used for:
  • Handguns and rifles
Would recommend: No
