The XC2-A-IRC is SureFire's smallest, most lightweight dedicated infrared (IR) handgun light. It features a recoil-proof LED that's focused by a multi-faceted reflector to create our broad 850nm MaxVision Beam(TM) perfect for enhancing the capability and the image quality of modern night vision to see clearly and farther into the dark. The XC2-A-IRC's 845nm infrared laser stands out when viewed with night vision devices and, once zeroed, rarely needs re-zeroing thanks to adjustment screws that won't back out from the effects of recoil. The XC2-A-IRC won't weigh down your handgun, making it a crucial addition to concealedcarry pistols among other applications. Its compact body is constructed of lightweight but strong aerospace aluminum with a Mil-Spec hard anodized finish, so the XC2-A-IRC is rugged enough for everyday carry.
