Great site. I found lots of info for the AK-47, but what about the AK-74? I was hoping to find dimensions/blueprints for the AK-74. Maybe blueprints for milled receivers for the AK-74. Any case if anyone could direct me to the right location I would appreciate it.
PS if I post this in the wrong spot.. sorry..
Edit: Found the magwell dimension which is a start..
AK-74 ejector tip should be 0.580" from the outside left side of the receiver on standard width receivers.
I have some fairly good drawings of an AK-74 receiver somewhere. Only thing I don't like about them is the total length is 10.25" which I find is about 1/16" longer than factory receivers. The references on the drawing on very good though.
I would appreciate a copy. I'm looking for references of the receiver around the location of the magazine.
This is a great post. If any of you guys have online links to blueprints of the Ak-74 please do feel free to share the goods.
Haven't looked around much yet have you?

My buddy just told me that someone is releasing very easy to follow blueprints for an AK-74 in the future. Did anyone else hear that?
WTF does "very easy to follow" mean? Or are you just trying to bump up your post count?
Building an AK using a blueprint is at best a "nice try". I have given up on them. The only reason they exist is to facilitate the hole-less receiver shells. The unfortunate truth is that there is no "accurate" template because the kits we receive ALREADY HAVE THE HOLES DRILLED! Thus a blueprint is never going to be accurate. Period.
To rebuild a kit, you really just need to have a good mechanical aptitude and you don't need no stinking blueprint. If you really don't have a clue, then you can look at sites such as mine that walk you through the conceptual assemblies which will help you understand the necessary steps. If you understand the basis of the assemblies, then you will know that you need to start with the trunion holes. Once you get those properly drilled and assembled, you proceed to the trigger guard holes. Once that is fit, you can go on to the rear stock tang. The top rails of course need to be trimmed, and the internal rails need to be welded. Everything else is a non-drill operation. So what EXACTLY would you have a problem with that you need a blueprint?
No Hope For Me
YOU WILL NOT FIND A SET OF COMPLETE BLUE PRINTS FOR A MILLED RECIVER AT THIS TIME THEY ARE NOT OUT THERE. YOU CAN GET TEMPLATES OF A STAMPED RECIVER TO LAY OUT ALL THE HOLES BUT ITS NOT A MANUFACTURES BLUE PRINT. THE SIMPLEST WAY IS TO JUST TRANSFER THE HOLES FROM A GOOD QUALITY FLAT.
A AK,S ALL DIFFFER SLIGHTLY FROM COUNTRY TO COUNTRY AND MODEL TO MODEL SO EVEN IF YOU HAD A MANUFACTURES BLUE PRINT IT WOULD NOT COVER ALL AK74 MODELS PERFECTLY.
NOW WHAT ID LIKE TO SEE IS A CNC PROGRAM THAT LEST YOU PUT A BLOCK OF STEEL IN A MILL AND HIT A BUTTON AND SPIT OUT THE RECIVER AND OTHER PARTS. IF SOME HAD THAT YOU CAN BET THEY WOULD NOT GIVE IT AWAY.
TAKE THE ADVICE FROM HC,S POST ABOVE. A STAMPED RECIVER IS NOT A BIG DEAL TO MAKE WITH OUT ANY PRINTS OR ANY THING ELSE IF YOU HAVE A FLAT OR BENT BLANK. I BUILD MINE FROM SCRATCH FROM TIME TO TIME WITH A SHEET OF 4140.
Well, Ohio Rapid Fire's code is probably for sale... I bet there was a copy of the code still in the CNC machining center when it went off for auction, too.

On the other hand, you're still going to need some custom-made cutting tools, and you'll need a large CNC mill to have the throat distance to reach in and do the locking lug cutouts. And when you're done... you have an AK receiver that doesn't have any rivets. Frankly, I'm not seeing any advantage to a milled receiver to start with.
