First off, I am an amateur, by now means up to the level of Bklyn C and M1lk, so I am not the guy to ask for definitive AK knowledge. That said, I did a screw build underfolder AK. Would have preferred rivets, but do not have the tooling or the funding for it. Parts kit came from ak-builder.com, polish underfolder with new headspaced barrel. Again, don't have the equipment to press a barrel. Their customer service was great, everything in the kit was great except the handguards, which did not match and were both in pretty bad shape. Build only took about 2 days at a constant but leisurely pace. Here is the result, and sorry to the traditionalists. Down the road I may try my hand at a red Tantal build with all classic furniture. By the way, if anyone is interested in building an underfolder, prepare yourself mentally. I debated moving to a free state to utilize the stock when it came time to fix it.

very nice sir.

it's good to see folks showing that an ak build, while more time consuming than an ar build, is not unapproachable.

and if i may be so bold with the op's indulgence. i recommend imho that no member lists his firearms collection in his sig tag or any centralized posting. everyone is watching everything you type.

this being said i always make sure to give the finger to traffic cameras as i go by. at least this way when they rig the things to send tickets to every tom, dick and harry when budget shortages dictate, you have a memento worth framing.

Definitely doable. I have a little metal working knowledge, gunsmithing for certain weapons, and a big DIY mindset. If only I had the funding and the shop.

Awesome!!!  I always liked the look of the underfolders best. I was thinking about trying a 74 build in the future.  What is involved in a stripped-receiver-up build?  I didn't realize that they could be screwed together.   Were any other special tools needed?  Thanks!

Good work!
Don't feel bad about the screws. Some time back it was the common way to build an AK before the correct rivets and rivet tools popped on the market. If you ever decide to rebuild it or replace some major parts that's when you will appreciate the screws. But for now just keep an eye on them and don't let the loose.

It is fairly simple....

1.The trunnions and trigger guard on the kit still have the old rivets in, these need to be drilled out. Takes some time, oil, and good drill bits.

2. After the old rivets are removed and the holes of cleaned up, the trunnions need to be installed. I built on a Nodak polish underfolder receiver, the only holes that had to be drilled on the receiver were the ones for the front trunnion. I made a template for these by rubbing a post-it with greasy fingers on the receiver. I then installed the trigger guard, lined up the barrel and front trunnion and tested for mag fit. My front trunnion protrudes from the front of the receiver just a hair, thats where I achieved best lock up/least mag wobble. I marked and positioned my post it template accordingly and drilled each of the 3 holes out with a 1/8 bit. I drilled each hole out progressively bigger, eventually filing to ensure it was lined up with the trunnion hole. I drilled the 3 holes on the left side first and tapped the receiver and trunnion with a 10-32 tap. Installed the button head screws, and then marked the position of the trunnion compared to the receiver on a 2nd post-it. Removed the left side screws and made a second template for the right side holes. Reinstalled the left side screws, and then drilled, filed and tapped the right side. It may have been a little overkill, but I was dead on with my holes, and all this with a hand drill.

3. On tapping the holes, this is probably the hardest part of the whole affair, and again it is not hard but mostly tedious. Lots of cutting oil, going a 1/4 turn at a time and going back, after each complete turn removing the tap and cleaning it. USING NEW GOOD QUALITY TAPS!!!

4. All screws got a healthy dose of red Loc-Tite at the end, after everything was thoroughly cleaned and degreased.

5. The underfolder stock was not hard to install, though it very well may have more moving components than the rest of the AK. Here is a link to instructions with pictures. http://www.novarata.net/ak-underfolder/AKbuild3.php

6. Weld stock, weld brake, grind down bayo lug.

7. At this point all that needs to be done is install the internals, gas tube, and handguards.

8. I opted to DuraCoat, installed a steel ventilated top cover gas tube, a tri rail lower, and Primary Arms red dot on MI mount. I also did a paracord wrap on the left arm of the stock to provided a cheek weld that wont melt my face in the summer and stick to my face in the winter.

Like I said, this is my first AK build, do not use this as a guide! Check with Bklyn C before doing anything with an AK!
I am typing this on the go, I may have left things out, but it is atleast the general idea.

Where did you get your parts from and did you fold the receiver or buy a striped receiver? Bottom line what do you have in the complete package not counting your labor of love.

Great job!!!  I did both a screw build and rivet build AMD65's, and I like my screw build better.  Like BKLYN_C said I like the ability to rebuild it or replace some major parts and every now and then I do a complete brake down, inspection and cleaning.

Yes, if having more than a weeks worth of food makes you detain-able indefinitely as a suspected domestic terrorist. What do you thing listing your entire lengthy collection of firearms in your signature makes you in the eyes of "Big Nanny"? :derr

Sorry for hijacking the thread... uh, I don't think i should have said that.

Funny you should ask. After grabner's goal last night i was telling Big J. That you know you should put this all down in writing. You know give us some guidelines. I don't know if it was the coors he was two fisting all night but he told me the truth is he just asks b/c what to do each step.
