I tried searching for 80% and lower and couldn't find anything and I'm assuming this would be the best section since it's technically DIY.  Does anyone know of a good reputable place to get a 80% lower AK receiver?  I got some AR-15 80% and I'm excited to get these started soon.  Knowing this damn country and it's politics, eventually buying these non-completed "paper weights" will become illegal one day.  I'm looking to get as many lowers for everything from handguns to rifles if and when ever that happens.  

P.S. Hopefully it'll be a source for replica Russian AK's.  You know the one that fires in any condition and world renowned throughout history

AK's don't have "lowers" which is why you're not getting any hits on a search. Do a search for Polish blanks and you should find a metric ton of information.

An AK receiver comes in two 80% forms, a bent blank, or a drilled flat.
They are just as the names states the bent blank is bent but needs precise drilling to complete & the drilled flat has the holes drilled in location but needs the two 90° bends done to be complete.
Here are a few reputable places that I have done business with.

I hope this helps

I've done em all and folding a flat is by far the easiest. Need a bender though. If you have a welder and some skills try Jack Squat's Flats. 3-piece weld together design in thicker sheet metal (.064" I think).

Sweet, thanks for the good info guys!

P.S. Any links for info on completing either one of these?  Also which version of the AK is the best?  Seeing that there are many different variations of this model rifle.

Lots of great info here: http://www.ar15.com/forums/t_4_64/141256_The_AK_Buyer_s_Guide___A_Beginner_s_Guide_to_the_AK_Platform__ask_all_new_AK_questions_in_here_.html

I see that this link is all completed rifles.  How do DIY receivers work with these?

The link is a good write up on the different versions of AKs. After deciding what style you think is the "best", you buy a parts kit and build it on your DIY receiver.

Here is one of the better tutorials I have found for building an AK. Unless you have a pretty extensive set of tools, it takes a lot to get one together. Skills such as welding, riveting, drilling, grinding, sanding, heat treating, and painting are required.

Unfortunately I don't have a lot of tools.  I will get the ones required to complete the 80% lower AR-15 receiver which is basically a drill press from what I saw.  I also have a powder coating gun, actually a couple since I got them dirt cheap brand new, so I can powder coat the lowers.  

From what you've said, probably better to get them sent out to be finished?  I know people do that with the AR lower receivers if they can't do it themselves, don't have the tools, and/or don't have the jigs.  Is that possible with AK lowers?

Yes. There are plenty of gunsmiths around the country that would assemble it for you.
