Hey everyone, I know Im probably going to get yelled at for this, But if tried to search. and cant figure it out. I Currently own two Surefires. An A2, and a 6P. Is there any rechargable cells that can work in both? I read somewhere (now I cant find it) that the A2 walls are too small to accomodate rechargable cells. I work in a machine shop and have no problem milling out the body. Any help, Or links to threads would be great!!
