AK 80% build?

1858 remmy · May 4, 2012, 01:00 AM

Hey i was wondering if anyone has ever built a ak from a 80% receiver and how hard it is? Im in the middle of building a 1911 so if its easier than that i think i could handle it

And if any one knows of a place to buy some please let me know

Are all the rivets already done on this '80% receiver?'

80% receivers on AKs usually mean one of two things.. either the recenver is bent and folded with no holes cut or drilled yet, and the end user uses a template to do this... or its a flat with everything drilled and cut that they have to bend with a shop press, and install the rails (usually by spot welding them on)...

thats it, theres really not much more to it, i doubt a 1911 would be easier than that

Ok. the one part im not understanding is where they need to be bent? 'i am estupid' as Schultz would have said.

AK receivers start as a flat piece of metal that is then bent to the appropriate shape.

A bunch of different AK flats:

The dies for bending them:

Or, the flat already bent, but without the holes:

It needs to look like this when you are done (scroll down):

umm.. a shop press works well for bending them.. but i believe a sheet metal break can be used as well.. and there are probably a number of quick and dirt methods to get the job done.. but i dont want to mention anything that could be potentially unsafe... so when bending a flat its good to have one of those tools around...

youd also have to heat treat the receiver, atleast along the bend lines and holes made in the receiver as well...

if you dont want to go through the work of bending it, you can get a pre-bent blank, but youll have to cut and drill the holes in it yourself with a drill press, and other tools... with a steady enough hand i was able to cut the square sections and the magwell out with a dremel following a template

so depending on what tools you already have, one style of 80% receiver could be easier to finish than the other
