Just checked out AWoO's Gun Broker auctions and he says that they run smooth without a bullet guide no matter what mag you're using. They are asking $110.00 for a 28 round mag. I'm assuming that they are using the M76 mag follower in the MG13 mag to get 28 rounds in a 25 round mag. I'm sorry, it just looks right in that rifle. I want at least one whether I build or buy one.

 

im interested in this mod as teh MG13 is a cool gun.

 

Here's a GB auction with a pic of one of their M76's with the MG13 mag installed. It just looks right.

Thanks Pookie!!! I shot him a PM to see if he could expound a little on modding the mag/mags for his build. I'm assuming either welding and grinding to profile both front and rear locking lugs, or fabbing the lugs on a plate, and spot welding the plate to the mag.

I did the former on some Lahti mags for my Tabuk clone PSL build, but I'm not real impressed with how it came out. One mag doesn't work, and the other will only feed about 75% of the time. If I try this mag mod, I want to make sure that the end result is going to be satisfactory, otherwise I'm just pissing money away.

Reverse-engineering a mag is tantamount to fitting a square peg in the proverbial round hole. It is an art, not a skill. It takes careful observation, time, and patience.

 

we used to convert MG 13 mags for our g-43s without modify anything but we had a small nub spot welded on so the mag would lock up properly and they did
I seem to remember a old old thread on mag conversions here

I've converted them to run in the hakeem.. not in a M76 yet.. they are like $25 bones at Suplus sights.. B2B

 

Thanks guys. I appreciate the help.

 

IMA-USA has them for $25.00, so I'll probably buy a couple and try it out.

 

2ndamndmnt, get in touch with me ,I can't send e-mails messages or anything on here yet.I need almost everything.Send me a list,morayman.....

 

Morayman, Im going to say this publically, not because I'm mean, but because something seems off and I want everyone to know. If you are a fellow enthusiast, then welcome to Gunco. If you're not a fellow enthusiast, but some sort of troll, then piss off. Something about your frantic urgency seems wrong to me, and I don't feel comfortable giving you my e-mail, especially since you have not offered your own as a means of contact. If you are truly interested in building a legal semi PPS43, then most of what you need can be had by purchasing this kit:

Again, if you truly are a gun enthusiast and I have offended you, I apologize, but something just doesn't feel right about your posts. Sorry, it's just that my gut is telling me to "leave this one alone".

 

Hrm not sure what a PPS 43 has to do with an 8mm build? Anyway... the magazine tabs can be done two ways... first, you can sand the mag at the proper spot to remove any phosphate, then simply start welding a bead. Let it cool down. Weld more. Repeat until the bead is big enough to grind to shape.

You can also use a 3/16" square rod (like from the metal rack at Home Depot) and cut it to about 3/4" long. Grind the rod on both ends to make a thinner area above and below the locking area. In other words, look at an existing AK magazine's locking tab from the side, and grind it to that approximate shape. Then weld the thinner sections top and bottom. Grind the tab to the final shape.

Either way, go slow and don't use too much heat, because welding on sheet metal is painfully difficult. If you burn through you will need to sand it smooth on the inside. Get it so hot the sheet metal warps, you can throw that one away.

I have done both ways on my caliber conversions and either way works.

To fit it, you need to load a mag into an AK and eyeball the way the feed lips sit in comparison to the feed ramp and the rails. The mag needs to ensure the bullet touches the feed ramp (not too high!) so the feed ramp can do its job of guiding the bullet into the chamber. Use a sharpie on the degreased mag body to get the approximate location of the magazine. Do the same with your normal AK. Using that as your guide, you can approximate where the tab needs to be located. If you grind the tab less than you should, you should have enough meat to fit it precisely. The good thing is you can weld more metal onto the tab if you grind it too much

As I recall my MG13 mag has a locking tab on the back. You can reasonably compare an 8mm build to building a PSL. Cut that mag opening in the receiver to shape and notch it in the back for the BHO.

8mm pressures are surprisingly lower than you'd expect for a full-size cartridge. Should be able to use a 7.62x39 bolt that is converted with little effort. Safety should be OK with a x39 parts. SHOULD be I don't have one because I simply can't talk myself into building an 8mm AK. I have tons of 8mm but it is devoted to my MG42.

 

Thanks for the info Pookie. Yeah, I have done the "build up with weld, and grind to shape" method with Lahti mags for my PSL, but I think I'm going to do something similar to the steel Galil mags. They have small machined plates that have the lugs as part of the plate, then the plates are spot welded to the mag body. Like you said, heat and distortion is the enemy, so I think this will be the safest method. By the way, this is for my M76. I'm not building an 8mm AK. But thanks for that info.

Now, as to the gentleman above and the PPS43 parts, he has been going to any thread where I have posted and hounding me about selling him some parts. Something about it just doesn't seem right, and I wanted to publicly answer him, so others would know.

 

Ah OK the M76 - it just clicked what you mean. I have seen mags for sale for them, but they are always a bit on the pricey side. My friend from Serbia used to carry one.

 

IMA-USA has the mags on sale right now for $15 each - better hurry!

 

Thanks for the heads up. Got some!!!

 

That sucks, by the time I got to them, they were $30.00!!!!!!!!!!!! I still ordered 2 each. Numrich had them for $15.00, but they're out of stock.

AWoO is now selling them for $130.00 each on their recently updated website!!!!!!! Nice mags. but dang thats expensive. If I can make 2 for $70.00, then I will definitely be pleased.

 

Does anyone that owns a AWO modified mag care to post close up and detailed pics. Follower, latch area etc. I'd like to start modding the ones I got for $15 a pop. Hopefully not too complex., A little welding and filing???

 

Here you go:

 

AKblue, I wound up having to cut the spine off the back about an inch and a half down from the top, then I cut the bolt hold open "fork" off the back of the follower. Then I welded a rear lug plate that I drilled off of a rusty PSL mag body. A little trimming/fitting, and viola!!! Unfortunately the other pics I took of the process are too big to upload. I have got to figure out the settings on my camera phone. Hope that helps.

This pic was actually before I had welded the plate on the back. I had just left a small piece of the spine to act as a lug when I was cutting the upper spine off. You could actually probably do it that way, but it just felt too flimsy since the spine is partly hollow for the bolt stop fork to travel through it. It did feed ok like that though.

I also removed about a quarter inch of material at the front top of the mag to clear the bolt lugs in the receiver. About 1/2" to 3/4" back, and 1/4" down. The front lug sits just fine once this material is removed. If anything it could maybe be built up a little for additional strength.

 

2ndAmenican,
Thanks for the narrative. I'll start to look and compare your words to the mag. Any pics you can take would be a great help as well. I'm working on a M76 project rifle and this would crown the build.

 

I have some pics from various angles to show what I've done, but I'm still in a position that the pics are too large to post, and I can't download a program to shrink them on my work computer. Most of my meager internet time is done while I'm at work, on my breaks of course. If someone is willing to shrink and post them, I can e-mail them the pics.

 

More pics:

 

I should have welded the lug on the rear about 1/8" higher, and shaved the front lug off and welded a bead back on 1/8" higher. It works the way it is, but would have been less trouble, less grinding, bending, profiling, etc... if I had done it that way. Then the mag would have sat 1/8" lower in the receiver, which would have been perfect. Might have even dropped it 3/32" in the front.

For the front lug, I would grind the factory one off, and weld a bead across the front right where the top edge of the original lug was. This should drop the front of the mag down far enough. You can see in the middle pic how much material I had to remove at the front of the mag to clear the underside of the rails/locking lugs. It was roughly 1/2" down, and 1/2" back, with a gentle radius. I wanted to leave some of the bullet guides on the front sides of the mags. Push a cartrige out of the mag, and you can see what I'm talking about. There are little pieces that protrude into the path of the bullet to gently guide it toward the centerline. I left just a tiny bit of these, just in case. I don't really think they are needed anymore, and I may shave them off, but until I take her out and fire it with these mags, I'm leaving them.


On the rear I used a PSL rear lug that I drilled off of a couple rusty mags. I lined the whole assembly just a hair above the top of the feed lips on the MG13 mag. Maybe .020" above the feed lips. BUT that's where it needs to go at least 1/8" higher on the mag, so that the mag will sit low enough to clear the bolt without much filing to fit. Mine was hitting the ejector tip so hard that I had to roll the lips over more to get some more clearance, as well as thin the locking lug on the rear thinner than what I would've liked. It's still nice and solid, and it's not going anywhere, but I would have rather it been thicker.

 

2ndAmerican,
Thanks for the pics and added information on modding a MG13 mag. This should help a lot. I hope to get on it n the next month or so. Will follow up as I proceed.

Cool. You're very welcome. Good luck.
