O-rings for Twisted Tip

[BiffRocko]

The button on my PV got pushed while it was in my pocket and the LR atty I had on at the time trashed the o-ring on my twisted tip (510 sized). Does anyone have a lead on the size and where to get replacement o-rings?

Thanks in advance!

The Danco #47 Orings at Home depot or a 009 at Harbor Freight are 2 that I know of...Thanks
