I want to get a good representation of the different Hungarian AK variants that were/are available in the US.  What do I need to add to my list?

SA85m fixed stock
SA85 Kassner Underfolder
TGI AMD 65

Is that all?  Is there a variant I would need to build like an SA85M with an AMD fore arm etc?

I don't know much about the Hungarian guns but am trying to learn.  Thanks for the help.

Gordon Tech SLR-100h might qualify...

It's a milled receiver type-3 AK. They were built on Bulgarian receivers using Hungarian parts so I suppose you could argue which country it gets to be. As far as factory built rifles go you've got it down with the Kassnar and KBI SA-85M's and SA-2000's. All the SA-85's are called SA-85M by the way.

Then there is the AMP-69 which you will only find if you're lucky. Built from a parts kit of course, not factory.
