What kind of receiver are you going to use ?

Romanians have chrome lined barrels, they are easy to tell because they have the hand grip on the front grip. I got mine on gunbroker for $105.

Havn't looked at what receiver I'm going to go with. Still researching.

I'm planning on picking up a Romanian parts kit from Gunbroker. I thought about going to the next gun show, but I can't wait. Got a few questions for ya though, if ya don't mind. I apologise if any of these have already been answered, I have ADD
or from the for sale section of both gunsnet.net and falfiles.com screen name "bocefus" I believe he sells the ones with the red saten background on gunbroker as its the same images he uses
Is this the skull bashing collapsable stock I would need?
collapsible stock
nope, plastic adapter. you might as well get a T-6 stock from www.tapco.com as its one piece (plastic) or just get the plastic adapter itself and get a AR stock for WAY less from ebay. ACE stocks sells the diffrent metal adapters but get pricy. but worth it
Also does the mounting for it count as the rear trunnion......I.E. would this be two US parts?
no, only the stock. the rear trunnion is still used with that adapter
But I'm also thinking....do I really need a collapsible stock like this? I like the fact that I could save a little room, but do these really collapse that far? It would save me a little money to just get a 4 piece set.
they colasps a bit

I thought about a folding stock but I'm not sure wether I like them or not.

I noticed in the rifles built on the first page you replaced the stock and hand grip (2parts), fire control (3 parts), and gas tube (1 parts) to make the 6 US parts you needed. But the reciever would count as a US made part wouldn't it? I'm going to get an unbent reciever to save a little money.
yup US reciever counts as a part
On the trigger group, do i need the single hook or double hook? I've noticed most of the time they are the same price. And is "G2" better than anyone else's US trigger groups?
G2 work great. all my shit is single hook and i see nothing wrong

So so far this is what I've got...

part........................cost...............US parts

romanian AK47.........$99.97
gunbroker.com

collapsible stock......$84.95..............2
fl gun works

pistol grip................~$20...............1


g2 trigger group.......$39.................3
tickbitesupply
--or akparts.com.......$37.95 *not listed as G2

Unbent reciever......$24.95..............1
akparts.com

Total...................~$270...............6

I plan on getting a front hand gaurd to match the stock/pistol grip when I get closer to completion, and a birdcage flash hider. And I didn't factor in the screws or other small supplies into the cost. Is there anything you can think of that I'm missing?

TIA for the help!


Edit: I just saw the link to DPHarms above.....

They have a Ewbanks receiver that is already predrilled and folded for $50.....are these any good or should I stay with the unbent recievers?

Ewbanks recievers require some rimming on the little tabs inside the mag well. I have done 4 on those and they work REALY well.

also look at http://www.tapco.com/product_informa...t=214&last=214

$200 includes romanian kit, colapsable stock, fore end, grip, and fire control group.

hey Doc, I just got an M-4 stock and am going to make a piece out of 1" stock like Mac made you. My stock has this piece that I assume is an indexing ring (the threaded portion has a slot in it that a tab in the ring rides in) ... it doesn't look like your stock was like that. Is that where you drilled that hole for the small allen screw in one pic ?

a pic like the stock I got:

my stock has a locking ring also. its just larger. and yup that "tab" area is where i drilled it to lock.
you can buy it here

Funny you should ask
A 2mo an a 16mo don't leave me much time.

Complete build...no.

I did finally get some free time today and got the jig dialed in.
1st one I used 3/16" for the side plates by mistake. So the receiver was 1/8th too narrow.

So I got some 1/4" and remade the sides.
#2 bend was too wide... somehow .25+.25+.75=1.3"
So I had to spend some time with some wet/dry and oil and worked on the side plates.

Finally got the width correct and I measured it before bending a flat.

#3 came out perfect.
I got the trigger guard attached.
Ft trunnion located, mags lock up tight no wobble.
Located the holes, drilled the receiver, front trunnion is screwed in.
Rr trunion located and screwed into place.

Now I need to finish up the barrel & gas block mods I am working on and get all of that put back together.
Then head to the range and test fire.
If everything works ok, disassemble, sandblast, park, and GunCote.

thanks
dale

no they are still the same stocks, nice try but if you cut off the pistol grip on a Romanian lower then yes you could

HOW TO MEASURE THE DEPTH TO DRILL THE FRONT RIVITS !!!!

1) you need a pair of calipers or a depth micrometer to be "accurate" you can eye fuck it and still be fine.

look at the front of the front trunnion right where the barrel sticks out.
see the trunnion? see the barrel?
That is the the max depth you can drill before hitting the barrel because neither the barrel or trunnion taper easy as fuck huh?
Just take a drill, put the point of the drill on the barrel, slide a stopcollar till it hits the trunnion and thats it.

ya need a picture ?

[usmcdoc14]

oh and as for "accedentaly" drilling into the barrel

big fucking deal look how deep the cross pin slot is drilled into the barrel and that is factory

[aloharover]

Was able to get some more time in the garage this morning. Here is some more of my progress.

The die parts

[aloharover]

Lining up the retaining plate and flat with a couple 1/8 punches

[aloharover]

everything bolted down tight

[aloharover]

Starting the bend

[aloharover]

Little heat and 8oz ball pean to de-stress the corners

[aloharover]

Bending the top rails

[aloharover]

A pair of bent flats (flats I made my self )

[aloharover]

The FAK-47 is starting to really come together

[morpheus]

nice work man! You making your own rails too?

you going to heat treat them?

Yes, probably from some 1x1x1/8 angle

Yes

looks like from a FAL. Try tapco. Looks like the $.99 break


I'm going to use a shortened STG58 break on my AK.

yep, brit FAL...slides on, held on by a little wheel pinned to the bbl...LOL

hope he threaded it or pinned it on...I have watched them fly downrange with the bullet...

Yes, Tapco.
FAL parts.
Brake, gas block, gas regulator, and gas block plug. Most of this stuff is a buck or two from Tapco so I ordered a bunch of parts.
Thats why I call it the FAK-47
Barrel is cut down. FAL gas block actually is a press fit over the brake and then the brake is a press fit onto the barrel. It will get drilled and pinned.
Inside of the gas block gets reemed for the piston, stock is threaded for the FAL gas tube. Regulator is going to be functional. Barrel is 16.5". With the folding stock its going to make a great little truck carbine.

My next build is going to use a FAL barrel, piston, and gas tube. 7.62 nato AK

All I can say is if you don't have a variable speed dremel yet get one.
I use a fiber disc to cut off the heads of the rivets, then pry the receiver off the trunion. Makes it easy to determin the exact size of the rivit and its center prior to drilling.

Use the fiber wheels and smaller cutting wheels to do all the openings and trim the rails.

Carbide cutter for general shaping, finish with sanding drums, or files.

They make an attachment for the Dremel so you can use a drill bit thingy for cutting sheetrock and stuff, kinda like a Rotozip.
That attachment actually makes a perfect depth gauge when used with the cut off wheel for triming the rails. Makes a perfect straight cut.

Polishing wheels and bonnets to clean up feed ramps and stuff (ok mostly for the 1911s)

similar style as aloharover:

cut off rivet heads with 4.5" grinder not giving a fuck if I chew up the receiver leftovers a little

pry off receiver stubs

sand rivet stumps smooth to the trunnion with the dremel sanding disks

center punch the rivets

drill a guide hole in the rivet using a small bit

drill out rivet to a few sizes smaller than what i will be tapping/riveting it to

remove rivet bits or grind them out the rest of the way with THE GOD OF ALL DREMEL BITS !!!
the tungsten carbide cutter !!
(large image so you may worship it)


The rear trunnion rivets I keep drilling larger till they "get stuck" on the drill bit and then pull them out using the bit.

I've seen the sheet rock thingy. But I bought an already made reciever for my 1st build. My 2nd parts kit I got is way worse than my 1st, so I'll make the reciever for that and have it be a beater rifle

The idea is from Sangrun's thread over at gunco
http://www.gunco.net/forums/showthread.php?t=18008
BTW the link is a pretty nice write up with lots of photos.

[aloharover]

OK, here is the current state of the FAK-47.
Passes the functions check.
16.5" bbl but thing still almost feels like a pistol. I really like the balance.
Going to make the perfect truck carbine. Thinking about saving up for an Eotech site.

Only a few items left on the to-do:

1- drill and pin the front gas block
2- make and install the cross support
3- drill holes for rear trunion.
4- heat FCG holes and rails.
5- order an ace skeleton side folder (will use old wood until it arrives)
6- finish the gas tube heat shield/rail mount (that can wait)

I might just be able to test fire it this week end.

Then can disassemble, blast, and paint.

ps. I only photochopped the background so as to not further offend Doc.
