Tuning Need help-Breech O-ring for .22 AA S410?

[JohnL57]

As the title says, I need the size for the breech O-ring for my .22 AA S410. I thought I had measured right, but no dice. Some help would be welcome!

Thanks,

John

they have schematics for the S410 and have what it looks like the o rings and seals you need.

Thanks, I can source O-rings in the US. and the schematic doesn't have the O-ring sizes.

I would think a Harbor Freight O-ring kit would have the right size, but pyramyd air has O-ring kits for the s410, no Vendor is willing to give the real size, just part #

This is what I use on my S510. I think that it’s the same as yours.
