I think I finally have this kinda, maybe sorted out on building the AA semi PPSH.

AA will modify your lower receiver, bolt and trigger assembly and will sell you the additional semi parts to install in your completed receiver.

The regulated part of these guns is the center section of the upper receiver so on all parts sets that piece is missing. At the rear of the upper receiver is the catch that releases the upper assembly so it tilts down for disassembly of the gun. As explained below, an old piece of the rear part of the receiver may or may not be in your parts set...the catch will be, but the old receiver piece that it slides on may not be.



Most PPSH-41 sets are now torch cut thru the trunion. On the PPSH-41 parts sets, many times the old rear receiver piece is still in the receiver catch, for example, the OOW PPSH-41 parts sets have it, but, again, they are torch cut thru the trunion.

The PPSH-48 parts sets sold by Nartron http://www.luminet.net/~nartron/prod11.html have the trunions intact, but the rear receiver piece is missing, but the catch itself is included.

To complete the receiver with the parts sets, you have a couple of choices: NOTE: The vendors/suppliers listed below are for reference only, I don't advocate one over another and other vendors that can supply these parts and pieces are welcome to add their names to the list so we have as many choices as possible.
1. If the trunion IS intact you can buy an 80% upper receiver from Prexis http://www.prexis.com/sten/51.htm and weld it onto the old trunion/barrel shroud which will require only one weld. According to James, you want the Prexis upper that DOES NOT have the integral semi rail because AA provides a piece to convert the upper to semi.
2. If the trunion IS intact and you want to do a little more welding and fitting and save some money you can buy a center receiver section and template from stenparts http://www.stenparts.com/Tubes/tubes.html and the rear receiver piece still intact in the rear latch from OOW http://www.ohioordnanceworks.com/parts/ppsh-41.htm and make two welds in lieu of one. With three separate pieces (rear upper, center upper, trunion/shroud) you'll have to take extra care to get everything lined up before you weld, whereas on the Prexis upper you are only aligning two pieces.
3. If your trunion IS NOT intact then you will need to buy an 80% full length upper and a trunion from someone like coldsteel http://coldsteelsolutionsincorporated.com/css,_inc_003.htm and do a fair amount of fitting and finishing. An alternative is to buy just a trunion from coldsteel and do a fancy job of rewelding the torch cut trunion housing and pivot hole.

I just ordered one of the Nartron PPSH-48 parts sets and the rear catch with old receiver piece inside from OOW...stenparts is on my way to work so I can get the center receiver section and template from him.

James at AA says the rest of the semi conversion parts to change the upper receiver to a semi upper are in the kit he's providing.

What I don't know about is the barrel length issue to get the barrel to a legal length of 16". My plan is to permanently weld a tube onto the existing barrel and lengthen it to at least 16" and then with an extra parts set, piece two ventilated barrel shrouds together to accommodate the longer barrel. I think Sten barrels are done this way to get them to legal length, but experts can correct me.

I just sent my parts to AA for modifying so I won't see the conversion parts back for a couple of weeks or so. By the time the parts return I should at least have the barrel shroud pieced together and my parts gathered up for the upper receiver completion.

A note of caution here, if I understand correctly, AA provides the pieces necessary to permanently install in the upper receiver to prevent installation of FA parts. If BATFE regulates the sequence of build on these guns like they do the 1919 then it probably is not a good idea to fabricate the upper receiver and weld it onto the old trunion/shroud without first installing the semi conversion pieces in the upper receiver and lengthening the barrel. Obviously, if we pre-fab the upper receiver with the ejection port and charging handle notches cut and weld it onto the old trunion/barrel shroud before installing the semi pieces or lengthening the barrel, it could be installed directly onto the parts set resulting in an illegal FA...bad ju ju. I haven't seen AA's BATFE letter, but hopefully that is explained in there...if not I would hope AA includes a written statement about the build sequence just as a CYA.

Again, I have not seen the AA conversion kit and I'm sure James will jump in here with any clarifications.

I'm looking forward to building this gun and will post pics when it's done. However, I will only post a pic of the finished weapon and not any detail photos of the build or of any AA conversion parts. I also have a five gallon bucket of sand all ready to test fire a few rounds when it's completed.

The receiver when in blank form will have to have the receiver block attached before finishing. The barrel lenght is fixed via a tube that you will sleave and weld onto the end of your barrel, it is supplied in the kit. If you have a complete torch cut receiver from back in the day you will want to be vary cautious in how you finish it and we will try to make not of the proper way to do so with a big fat disclaimer. Keep your nose clean and everyones happy ;) !

Talk about confusing! Luckily I have 3 of the CFS PPSh-41 kits and will have my 3rd PPSh-48 kit from Nartron hopefully in a week or two...hopefully with these kits my bases will be covered.

Loboslanding, thanks for you very informative post and I will read it again later when my brain isn't so fried!

lobo, can you post a pic of the end piece of the receiver that comes from oow. I need 5 of them and was curious as to how much overlap i will have with my other pieces.

Realise that the only reason the PPSH-41's that are in have torched trunnions is due to the importer opting for the primary issued demil from the Bureau.
Alternate acceptable demils can be obtained other than the standard 4 cut method. Nartons are demiled in saw cut fashion via torch by removing and destroying the complete center section as illustrated in Lobo's schematic.

The muzzle support must also be cut as well.

xmarine, here's a pic...only about 1/8" of the old receiver chunk sticks out in front of the catch. The center section from stenparts (that would weld to the chunk shown inside the rear catch) is about 12" long so if you opt to use his you will have plenty to work with and about 2" to spare.

Catch is included, but not the rear receiver piece on the Nartron set. Re-read my original post for the details.

Ppsh 41/48

SO...does anyone have an extra "Rear receiver piece" that they could spare. Not the catch cover...just the tail or rear of the receiver.....
Thanks

Those are really hard to find and I think when folks figure out that the OOW latch still has the piece in it and that they will sell just that latch by itself, they will get gobbled up at $35. I don't know anyone selling individual parts for PPSH except for OOW.

The following is a new source of Ppsh41 "kits". Send your Rubles to Putin (A former KGB agent, by the way) , as he is the contact man. He is also a good friend of the Alphabet boys (who have received most of their training from him), so there should be no problems. LOL

A rough translation of the first post is:

Уважаемые Коллеги!
При содействии нашего постоянного участника Антипа Глымова из большого количества макетов ППШ было отобрано сегодня 8 образцов с разными клеймами.
Все они весьма интересны и заслуживают внимания.
В процессе расшифровки клейм нам не удалось выяснить абсолютно всё,что мы хотели узнать,а именно - завод-производитель того или иного отобранного нами ППШ.
Поэтому мы с Глымовым очень надеемся что многоуважаемые специалисты Ганз.Ру помогут нам в определении мест "рождения" этих ППШ.
Будем крайне благодарны за дополнение этого собрания информацией по другим клеймам иных,не представленных ниже,заводов-производителей ППШ.
Я пронумеровал на картинках ППШ от 1 до 8,чтоб было более понятно и наглядно.
Для начала фото многоуважаемого хозяина всего этого богатства.
И фото, собственно,богатства.


Which means (roughly):


Respected Associates! With the assistance of our permanent participant in Antip glymov from a large quantity of mock-ups PPSH were selected today 8 models with the different marks. They all are very interesting and noteworthy. In the process of the interpretation of marks we did not succeed herself in explaining absolutely everything that we wanted to learn, namely - the plant- producer that one or other selected or another by us PPSh. Therefore we with The the glymovym greatly hope that the respected specialists To ganz.Ru they will help us in the determination of the positions of the "generation" of these PPSH. We will be extremely grateful for the addition of this meeting by the information on other marks of others, not represented below, plant- producers PPSH. I numbered on the pictures PPSH from 1 to 8 so that it would be more understandably and it is clearly. For the beginning of the photo of the respected owner of entire this wealth. And photo, strictly, riches.

I have a bunch of images that I have collected over the last 5 years. I will post most if interested, including detailed schematics I downloaded from somewhere.

The following link provides some more info as well as the link to the diagrams, one of which I posted here.
There is also a link on how to load the Ppsh41 drum:

http://www.ppsh41.com/Drumload.html

There is also a Ppsh41 forum that has been around a long time that I have posted to, but it is not that active right now:

http://p211.ezboard.com/fppsh41ppsh41forum.html

It would be nice if vendors and those interested in building a Ppsh41 would start posting there questions/information/sugestions on that forum also.
