Looking over the mg13 parts set and cut reciever IMA currently has available this one looks like a fairly straight forward build as the fcg is a very simple hammer/ trigger /sear assembly.

My current thoughts on using the atf approved demilled rec scrap to build a new semi reciever are as follows, first to machine a cylindrical bushing to go in the forward most piece of the scrap that the bbl extension/bolt carrier rides in and weld solidly in place eliminatuing the ability to insert the original fa carrier/bbl ext. Important to do before rejoining to any other scrap. Since ATF seems happy with the filling of one bolt rail cut in the reciever in the bren and rpd it might not hurt to do this also, or it might suffice alone as it does in the other approved designs, Both these mods can be completed before any pieces are rejoined and once done, then welded together it would be impossible for the original bbl, bolt, or bbl extension/bolt carrier to be inserted so I believe it ould not be an mg rec at that point, although without atf approval there is no definite answer, but the redundancy of using both methods should show plenty of effort on the builders part. And the reduced ID bushing would not be accesable for removable once all welded up.

The mods to the carrier/bbl extension would then involve the removal of the teat that trips the auto sear in the original lower. After the all important semi mod to carrier has been completed  it would be time to then remove the rail that mates with the rail welded up above and the front cylindrical portion would have to be turned/ground to insert in the new bushing. Likewise the bbl od will have to be turned to to fit the reduced ID rec.

 

So far this all the thought I have put into the project

things still to be addressed are

possible mods to upper to block the auto sear/trip in lower from bieng introduced into reciever if some knumbnutts tryed tempting fate, might be neccesary to increase the width of the lug on the bottom of reciever that lower clips on , so an unmodified fa lower cant fit period, maybe just welding the pivot hole up and drilling a smaller size or a combination of both? I believe redundancy on these issues never hurts.

Compliance parts count? not sure if it applys but since its mag feed and not ground mounted/heavy I imagine  922r applies. Maybe we can just squeze american ar/ak/fal fcg in place to cover a few parts, mag fllower and floor plate look simple enough. No flash hider or threaded bbl, unless bbl jacket bushing counts.

Not sure which factory parts in the lower have to be bobbed, chopped, or  tossed , havent studied fcg at all, surely somebody here has though.

My understanding is if the gun is not on the list then it does not have to comply.  Like the MG42.

OK I stand corrected EZFEEDS' explanation makes sense.  I quote him below:

yep, and the 1919 is not a 922R applicable weapon either.

The only reason the RPK is because it qualifies as a "rifle" and not a "firearm". There are big diffferences in these classifications. "Firearm classification" is just a general classififcation that is set aside for weapons that do not fall into any other clasification.

Here's a short and quick list for you:

  1. "rifles" (only semiautomatic) all weapons in this classification alone are 922R applicable 
  2. "SBR", "SBS", "firearms", "pistols", "AOW", weapons in this category ARE NOT 922R applicable.

Weapons that are belt fed, fire from a tripod, are heavy, and all aspects of a ground gun are usually classed in the general category as "firearms". 1919's, M2's, Maxims, Vickers, MG-34/42, and RPD are classed as firearms due to heir weight and impracticality of being SHOULDER FIRED and that aspect is necessary for a weapon to be classed as a "rifle" since a rifle is defined as a shoulder fired weapon.

MG-34/42's are not 922R applicable because they are not "shoulder fired" but rather "shoulder supported" weapons. THERE IS A DIFFERENCE!!!!!!!!

The RPD, specifically our copies of the RPD will NOT require 922R compliance parts. Dont believe me???????

Look here. Go to the RPD section and click on the ATF letter at the bottom of the page.  http://www.vectorarms.com/indexframe.html  (note, the requirements for marking are not required for homebuilds, only commercial manufacturers)

Weapons like the RPK, Bren, Madsen, etc,,, that are light magazine fed weapons are all 922R applicable because they are classed as "rifles" namely due to their ability to accept a magazine.

You guys need to learn this and teach others the same. Only through  education will our hobby ever be sucessful and survive.

Pull together guys and spread what you learn. :)

This one ought not to be 922R applicable because it can be considered a ground gun and not shoulder fired.

Should have an awsome amount of room in that lower for a simple replacment FCG like PBB said.

Is this thing hammer fired? If so it might be possible to just eliminate the components in the FCG that facilitate FA fire, plane one side of the original FCG down, add a shim to the inside of the trigger housing to prevent unmodified parts interchange, and then be able to utilize the original setup in a modified form.

Yep its hammer fired, looks like an ak hammer and sear except a few extra parts, I think just a matter of eliminating the fa trip and a block welded in place. But I've not taken enough time to look it over.  If I knew the 922r status for sure I would move this one up on my list of projects since it should be nearly as easy as assembling a fal.  I know the mg13 was originaly a different gun with diff designation and  fitted with a huge water jacket and fired off a tripod, was then fitted with a light jacket/bbl and rebaged the mg13. Its def not on the non importable list, but it does use a conventinal magazine.

anybody that appreciates over engineered over machined german MG's should really jump on one of these while IMA has the sets with rec scrap. Other than bieng a little ragged from poor storage these things are awesome.

I missed the kits from IMA w/receiver scrap.  Anyone have a kit they would like to get rid of for cash or trade?
