I've got both the AK Interactive and the Ammo from Mig range. On that, make sure you're looking at Ammo from Mig, and not the different Mig Range. Loooong story, but Ammo and AK have the same pedigree, though they are seperate companies.
They're marketed as for both airbrush and conventional brush, which is true. Both use a very fine pigment, which doesn't take long to separate from the carrier liquid and will need shaking before and often during use.
Both ranges also have what they call "scale effect", so their colours have been optimised for use in scale models so may not appear to be a 100% perfect match with a colour swatch.
What attracted me was for their WW2 range they sold colours with perfectly matched tones, for example their russian green dark base colour through to the russian shine paint (final highlight colour) is both colour and tone matched all the way. As an airbrush painter this is a God send as I don't have to mix graduating tones and I can do an army without needing to mix more colours part way through, getting the same colours across several painting sessions.
The paints work well straight from the bottle to the airbrush, but I can and do thin them. They all dry super quick in Sydney's dry weather, so have found I use smaller amounts in smaller cups to make sure I'm not shooting thick gunk. Thinning it doesn't seem to impact the fast drying.
The colours and tones sets are really good as conventional brush paints, and if I want to brush on specific armour colours they would be my first port of call. They have a broad range of colours and colour sets from WW1 to modern day Ukraine. I've got both companies products, though discovered the AK range first so they are the bulk. Mig Jiminez split from AK acrimoniously and started Ammo from Mig, but they emulate each others range for the most part. Ammo paints often come with ball bearing shakers in their acrylics, a nice touch.
Both have had some poor batches come through, I haven't the links but do some research as I know AK changed labels to indicate the new and improved acrylics.
Their enamel washes, filters, weathering effect paints are the stuff of dreams. I would recommend these with no hesitation. They are amazing.
Sorry for the long reply, but definitely do a thorough bit of research on both and get a variety of opinions as I know they've got their plusses and minuses. Apart from the drying issue and needing to give them the shakes often, as an airbrush painter I'm happy with the paints. As a coventional brush painter they're really good. And I adore the enamel wash and effect range.
