Not sure what size my DonnyFL SUMO is

[Wannab12]

I'm looking to sale a DonnyFL SUMO that I think is 22/25 but I'm not sure and it's unmarked. I measured the exit end and got 8.79mm. I can't find a chart to be sure, Does anyone know where I can find more info?

Thats .346 inch likely .25cal. Might clip pellets on .30 cal but will shoot.

Thank you for taking time to do that.

I’d email DonnyFL, they have to have the specs.
