EFW3 Filter Washers, filter fit

[jamiesmithnc]

Hi-

I got my EFW3 a couple months ago, the 7x50.8mm variety.

I finally got my filters in (still no mount), and after panicking for 20 minutes found the screws and washers.

I got everything mounted, but those washers sure seem kind of small.  All of the filters seem to be in place, and I am not hearing any sort of rattle, but some of them really seem like the washer doesn't even extend over the edge of the filter recess.

Has anyone else had experience with this?  I would hate to get to the dark site and have a $$$ filter come loose and break. 

Are there slightly larger washers available? I have it direct-mounted to a 16200 if that matters, wouldn't want them to get in the pictures.

Thanks,
