I left the extra O-rings from my P16 in my bedroom, and my girlfriend tossed them away while she was cleaning. 
I have 2 new 16340s which are slightly smaller than the IRC123s that came with the device. So, the battery is sliding around slightly.
What size are the O-rings? Can they be bought at a hardware store?
Thanks.
Gary
