Doc's new Project: 9mm AK-47

usmcdoc14 · 08-24-2006, 05:28 PM

This is for the advance level build your own fucking assualt weapon students

what I am doing is building an 9mm blowback operated rifle using a suomi 9mm sub-machinegun barrel and magazines and ak-47 reciever and fire control group. The project started as a from scratch upper and using a FAL lower but it brought the suck

and what was odd is at the same time I was saying "Fuck it, I will use an AK reciever" is when I saw other nutjobs doing the same thing on gunsnet.net. One person over there made my life a LOT easier but we will get to that later.

Here is a rough mock up of the weapon to show what it will sorta look like when done. Please note that the barrel in the pic is just a chunk of spare AK barrel not the one to be used when its done.

Components:
AlohaRover AK-47 Receievr blank
Romanian AK-47 front trunnion, grip,bolt carrier,Gas tube and rear sight block
milled AK trigger guard
Tapco G3 FCG
FAL front gas block
Tapco FAL picatinny dust cover

(YES it will work)
Suomi barrel and drum magazine
AK-74 bolt

Now I am making a blowback weapon so the gas portion of the AK is being kept for weight (inertia and delay) and for alignment. But the AK is a locking bolt weapon and I need a fixed bolt.
TAAAADAAAAA!!!!! mill out the bolt carrier for the 74 bolt to fit in the locked position.

Now the reason I am using a 74 bolt is its face diameter is 10mm so it will fit and feed a 9mm round perfect. you WILL have to sleeve it to fit the 47 carrier.
here it is is the rear locked position:

And side view:

I also REMOVED the locking lugs inside the front trunion. first by just leaving the flats but then as I fit and finished I found I had to shorten the distance fron the barrel to the feed ramp to assure good feed. I ended up taking a good inch off the back of the trunnion.

The bolt is now guided and kept in track by well...the fucking guide rails

usmcdoc14 · 08-24-2006, 05:43 PM

Now you can go and cut up an old soumi magazine well OR

you can cheat and use this guys'
http://www.lichtenbergresearch.com/index.html
His shit is pimp and very well made and has a feed ramp built in.

and If you slide his right up to the bottom of the guide rails it is a perfect fit and feed

Now here is the distance from the magazine to the barrel position

Now I kept the side part of the trunnion as it will be part of my bolt block that will act as a stop for the forward movement of the bolt and assure correct headspacing and not wear the bolt face.
Here is the veiw from the magwell to the ejector

And this is how much the trunnion is moved BACK !!

so YES I will have to cut down the bolt the firing pin and the recoil spring.

Now for something neat

I had a spare Tapco FAL rail cover and was mocking it near the ak and found that if I add side dust "skirts" it is a FAWKING PERFECT FIT !! So it will have a full rail and will hinge off where the old rear sight used to be. it mates perfectly

so it will hinge on the front and have a solid mount on the rear. The recoil spring will NOT touch the dust cover. And once I find some cheap STEEL picatinny rails I will chop the FAL front gas block and run rail on that AND the gas tube and use AR flip up sights that will co-witness with an EO Tech

That is what I would call "Frankensubgun". It just screams out, "BETCHA CAN'T WAIT TO SEE ME BLOW UP!", though I am confident enough in your work to know it won't.

Fawking sweeeeeet.

I've got a spare AK receiver and a suomi parts kit just collecting dust...

so once you get yours finished I might have to copy it

Frankenyota · 08-24-2006, 10:49 PM

Holy shit Doc, you are definitely to the PhD level of "gunfuckery". I hope the thing works out for ya! I got to shoot a real (FA) AK a couple weeks ago, it was ok but my semi AK pistol is just as much fun, bumping a 75 rd drum rocks.

Awsome tip. Going to have to get one of those and give it a try for my FAK-308 Carbine

Just curious, how does the chubby jesus-lover roommate react when she comes home and finds you sitting at the coffee table with evil black gun parts spread all over, deathmetal cranked on the stereo and porn on the computer screen?

Perfect examples of why I'm single..

0ILBURNER · 08-25-2006, 07:44 AM

Wow - that's some hard-core weapon fab shit right there, man.
So much for interchangeable parts!
I'd love to see a vid when you get it working

I will post pics of the skirting and shit so you have an easy time of it. I am just debating if i want a "flat" ass to the gun to the stock mounting (gonna make it a folder) or if I want to machine a chunk of aluminum to give it a more "tapered" ass like the top end of a MP5 or a G3

dammit, no emotional truma

why do you think I am using a barrel with a near 1/4 thick chamber with pistol ammo

4runner · 08-25-2006, 06:28 PM

I was looking the same direction a couple weeks ago...I love the suomi shroud and comp...

4runner · 08-25-2006, 06:29 PM

oh yeah, the comp...

4runner · 08-25-2006, 06:30 PM

or you could get sidetracked...

I too love that barrel shroud but that fucker is HEAVY !!

so I decieded to slim that heavy pig down a bit.

questions:

a. legality? paperwork necessary?

b. are you using anything more precise than a Dremel for your 'machine work'?

Frankenyota · 08-25-2006, 08:10 PM

One funny coincidence is that a good friend of mine just bought a 9mm AK. I have no idea what pieces or parts are in it, but if you'd like some pics for comparison purposes I'm sure he won't mind.

A) read the "How to build an AK " thread

but to save you that time in its cliff note form = yes legal, no papers needed.

b) is there anything more precise ?

yes dremel

the only machine work that has to be balls on is the barrel and the headspacing. everything else in an AK can be "off" and work just fine...ok it can be bent in an arch and still work

Like I said, I am sitting on the living room floor and doing this build
