Okay, today my Solarforce parts showed up and to my chagrin they don't add up to a flashlight. I got the tailcap, 1 x CR123A extender and a bezel. I'd thought the Solarforce stuff was basically a Surefire clone but it's not; the bezel fits a 6P but it won't attach to the body sections of the Solarforce. Obviously I'm missing a part, but what part is it?
