My next dream AK build - Finally done

[beanz2]

Not having the talent that some of you exhibit here, I will have my next AK build done by Mario Fraire from Piece of History Firearms. I have queued up for my turn and now it is time to accumulate parts.

My goal is to have an East German SBR AK with a folding stock. It has to have a factory DDR look. My wish is to have the one in the middle of this picture:


I have been told that the model designation is incorrect in the picture, so I won't call it "AKMS-K" or "MPi AKM-K"

I'm starting with a fixed stock East German AKM kit:


Then I'm adding a Palmetto State Armory FN barrel, cut to length.

For a stock, I'm going for an East German wire folding stock from Apex:


A JMac Customs GBC-13 gas block will complete the looks:



I need to source the receiver still. I will have Childers make me one with matching serial numbers. My questions are:

1. Which receiver? I think the Polish stamping AK47.

2. What stock cut? I am thinking a Fixed Stock cut is what the wire folder is designed to work with. Am I correct?

3. Trigger humps? Do EG guns have trigger humps?

4. Selector notches? Straight or angled?

5. Reinforcement plate? Do EG guns come with reinforcement plates under the grip?

6. Spot welds? Do EG guns come with spot welds on the front?



I guess there is a lot of research I need to do before I order the receiver, but by posting this I hope to shorten my work a bit

Fixed stock is what you want. The Polish is probably your best bet. Not sure what you mean by trigger humps. No reinforcement plate. 3 spot welds

Selectors very by years

Make sure your donor barrel does not come with a gas port already drilled as the jmac block might not cover up an AKM angle drilled hole.
Also make sure your builder will recontour the barrel for the Jmac block as a proper AKM barrel won't be profiled far enough back for a 90 degree block.

Your Integrated Front Sight Base / Gas ( FSB / GB ) block may be an issue.

Your parts kit features a 45Degree GB. The GBC13 GB is a 90 Degree unit.

The gas port may need to be corrected.

What I did in a similar situation ( modifying an AMD65 into a Krink lookalike ) was to take two standard separate pieces ( GB and FSB ) and have them modified by a gunsmith - It was cut and welded the Sight Tower onto the Gas Block; in order to mimic the Integrated FSB / GB look.

JMAC used to also sell the flash hider as well. I still have one to go with the gas block.

[SVT-40]

That EG folding stock looks like the 5.45 version.

Yes there is a difference. It's in the size of the sling loop and finish.


The 7.62 folder has a smaller loop and a duller finish.

[AKSOG]

[Yup the 74s were painted and the 47 were blued. Same with the recievers

Thank for you for the answers! That saves me a bit of research.

By trigger humps I mean these:

Also make sure your builder will recontour the barrel for the Jmac block as a proper AKM barrel won't be profiled far enough back for a 90 degree block.

Hmmm, not sure if PSA sells them undrilled for a gas port. I have basically two choices:

and
https://palmettostatearmory.com/ak-1...ome-lined.html:

I'm not sure what the differences are. The gas port locations seem to differ a lot. Maybe it's worth ordering both and comparing them side by side?

When guys convert guns by using the Bulgarian combo FS/GB, they don't have to reprofile the barrel, right? I probably should ask JMac.

I guess if I have to, I can go for the look of the third gun I posted above:

But that combo front sight/gas block looks great to my eyes.

Hmmm, I have another wire folder I bought a while back, but, alas, I can't seem to find it

Yes, I'm going to have POHF blue the gun. I heard blueing is one of their specialties.

You need a 100 series (103 or 104) barrel to use the 100 series jmac gas block.

You do have to reprofile to move from an AKM to a 100 series gas block on many barrels as well as close up the AKM angled port because part of the port peeks out from in front of the gas block.
I have one such job on my shelf right now.

You do not need to reprofile when re-working a Saiga as a Saiga already has a 100 series gas block.

Thanks, Randall! I opted for the 103 barrel. Hoping PSA will stick to true 100 series specs.

Here is a side by side comparison of the two different EG side folding stocks. The 7.62 is the small sling loop. This stock has a almost parkerized look to it's finish, as compared to the 5.45 which almost looks powder coated and shiny. The actual metal block that fits into the receiver also has different casting.

[SVT-40]

A pic I found on the web... Actual rifles not clones. No bumps, at least on the left side below the trigger pin. Are you going to get a optics rail?

I coundn't find any pic's of the selector markings for the exact rifle you want... But most of the 7.62 selector notches look to be "straight" meaning parallel to the top of the receiver.

[beanz2]

Awesome reference, SVT-40! Ok, no trigger hump then.

Yes on the side rail. Those OG optics rail will be hard to find. I have nothing that looks like them, the closest I have are Bulgarian rails, but the central depression will not be oval like those in the picture.

The external appearance on the stock hinge looks close enough. If needed, I can see if I have a suitable sling swivel donor. I still need to find that missing wire stock, dang it

[SVT-40]

The one you are looking for is the most common type.

[beanz2]

Without going through and cannibalizing my parts kits, these are the loose optic rails I have:


So it seems like the MPiKM-K uses a rear trunnion rivet pattern like in the lower two rails in my pic? Aren't those an AK74 rivet pattern, not AKM?

The last rail on my picture look like the MPi-74N rail pictured on akcollectorssource.com. So at least I can use that one.

These Russian AK-74N rails seem to have the correct oval-shapes as in your picture above:

A pic I found on the web.

The more I research, the more I am confused
