MP40 0-Ring Size

[jbeanz24]

Hi there does anyone happen to know the size of the O-Ring for the MP40 wet side ? Mine has somehow stretched and no longer fits . I know eco tech sells them on their site but I’m trying to avoid shipping costs if I can .

How much did it stretch?
Little dow 111 and try to fit it back in.
