Specna F249 Hop Unit compatibility

[Hudson]

I recently acquired one of these second hand, and I'm wanting to know from anyone that might have had one what hop units (if any) are compatible, should I decide it's worth it to upgrade at a later date.

They look different and smaller to the usual A&K style ones, So I'm wondering if they'll still be compatible with the available aftermarket units or not.

I think the Novritsch one is compatible.

I might have one spare if you want it, i'll have a look.

The standard A&K one is absolute dogshit.
