Huge shout out to @surefire_llc for being one of the best companies out there! Lost my locking bar for my x300 being an idiot and fiddling with my light in between swapping it from my firearm to the force on force Glock at the low light class I attended earlier in the month. I was sure I was gonna have to search the web and purchase a replacement but I figured I'd contact Surefire first. The dude was super helpful and sent out a new pair of them for free. Didn't even have to pay shipping and got a free sticker! Dude, you guys rock Surefire!
