I have a brand new Surefire M6 with the larger military only Combat Bezel. The light retails for $425. I have the Light a 250 lumen and 500 lumen bulb and tactical holster. The 500 lumen bulb is supposed to come with the light when you purchase it, however it has been on backorder for 8 months and you receive a certificate for it when it is available. This is the second brightest light Surefire makes second only to the $5500 Hellfire light. This light is intended for operators to mount on a M4. Im interested in trading it for any glock in NC FTF.
