Well why I am asking is becuase I was having a little bit of trouble with my tailcap. I was having to crank it down a little bit more than I wanted to be able to turn it on.So I thought I'd just give this spring a little stretch and of course I pulled it off.So I was able to get the spring to go around the solid center post of the tailcap as I thought that is how it was before but now sometimes when locked out it might flicker on with a hard press.
