Theres only 4 articles in the krinkov section and none answered my question when I read them, does a krinkov take a standard ak reciever or des it have its own size?  Do I need a stamped or milled?

Plan on using a side or under folder? The the receivers are the same other than the cut for what ever stock you plan to use. Side folders have to have the back of it cut for the folder parts and also the front of the receiver gets cut and drilled for the folding stock latch. It is the same for the side folder AK74. I built a AKS74 and that side folding stock was a pain in the arse to get right.
Most I have seen built are on stamped receivers but there are some milled one running around out there too.

A standard AK receiver is used for Krinkovs.  You can build one on stamped OR milled depending on your budget.

The only thing with building on a milled receiver is that you will not be able to install the side folding stock.  There are no milled receivers currently made for the side folder.  Firing Line makes U.S. made milled receivers for standard and underfolding AK variants.  They are allegedly working on a side folder.  Check with them for the status...

If you go with stamped, you will need to track down the template for the rear block (underfolding or sidefolding).  I have been cleaning up a couple of the drawings that have been circulating and will try to get them posted for you.

Krebs Customs has U.S. made gas pistons that will fit the Krink.

Any U.S. made fire control group will work in the Krink.

I want to do a AK74SU style like Osama's only with a underfolder, I like how the underfolders look and feel compared to the side folders.  Another question, if you use a american made reciever does the parts count thing still apply?

Yes, the US made parts still apply with a US made receiver. Just ones less US part to add to it.
Are you planning on going the short barrel rifle route or using an bartrel extension of some sort?

I haven't seen any 74s with an underfolder so go for it. Can't wait to see pics.

Im gonna go SBR if I can, Im going to contact some people in my county to see how the reg's are before I go ahead with the buildup.  Otherwise I might end up with one of those fake silencers, Im trying to avoid that though.

SBR is a pain in the ASS.  IIRC you need.

Sig. from local CEO doc.

Another form with $200 tax stamp (didnt we go to war over tax stamps?)
send it off, and wait 3-6 months.

Check out Uzitalk.com these guys do this stuff all the time, seeing they own large numbers of SBR, F/A and Suppressers.
