The MG34 Repair and Troubleshooting Thread

Who else has an MG 34 308 conversion kit?
I got my 308 kit today.
The barrel seems a bit skinny, especially compared to the original.
The belt was split into 5 round pieces. What's up with that?
I thought full belts were allowed. Am I wrong?
Any tips or tricks I should know about?

I have the BRP kit that IRunGuns imports - it’s great! A couple of thoughts:
- yes, the barrel is a thinner profile near the middle - probably has to be a bit lighter to maintain the barrel recoil and unlock characteristics with the lower recoil impulse of the .308 round compared to 8mm. I love the German-marked barrel extension - very well made.

- BRP ships this kit to California and other states with magazine capacity laws that apply. In Canada, pre-1945 belt designs are exempt so long as they are not reproductions, so use original German or Yugo belts and you can go 50 or even 200 rounds. Use links like the M60 and you’re limited to 5 rounds in theory. The BRP kit includes a feed tray spacer for links.

Reference: http://laws-lois.justice.gc.ca/eng/regulations/SOR-98-462/FullText.html

Part 4 (3) (2):

“(f) is of the “belt” type consisting of a fabric or metal belt, is not a reproduction and was originally designed or manufactured for the purpose of feeding cartridges into a automatic firearm of a type that was in existence before 1945”

- the BRP kit includes a feed tray adapter for the shorter .308 round that requires drilling - I didn’t install this and have never had a feed problem, so maybe try with the unmodified feed tray and you may be OK.

- you have to replace the rear feed pawl - 5 minute job with a punch - feeds both .308 and 8mm with total reliability after that.

- without the feed tray spacer, you can chance calibers by swapping barrels in less than 10 seconds - it’s awesome.

- older German MG34 belts hold the slightly larger diameter .308 rounds less tightly, so no feed issues. Lightly lube each link with a barrel brush and gun oil.

- you may need the smaller diameter booster cone with .308 - my 11mm cone works as I have the lighter German firing pin spring installed in my bolt.

Enjoy - let us know how it goes...
 
I got my BRP kit from IRG also.
I'm using an original FP spring, and my booster is 11mm also.
I will try using the feed tray without the mod first.
The 308 bullets are against the front of the feed tray without the mod?
The belt that came with my gun is made for 50 rounds. How to tell if its original?
So a WW2 belt is needed to be legal?
Were can I get more spare parts.
Thanks.
 
When I get home I will look in my black book for the load data that I use. If I remember correctly it's the same data published in the Lyman book. I use the imr 4350 and 4064 powders

As for spare parts the only place in Canada that has anything is Marstar. Sometimes you can get stuff off e bay and gun broker but usually are from overseas sellers. Hard to get parts from the US because of the import bs and itar
 
Been out of the thread for a bit -

So cool to see the support from members,

My gun is still back at Wolverine - It was received there July 13th. They are waiting for parts apparently? I have to email them and ask as they never contact me. I'm seriously unimpressed......

Once I get the gun back I will take it out and field test it.

I'm in Ontario for work but I appreciate the offers to help.

July 13? Holy crap that was a long time ago!
Do you know what parts they are waiting for?
Hopefully it's in perfect order when you get it back, sucks to have to wait that long

I contacted Wolverine in regards to parts a couple weeks back and they have no parts and can’t get any. That’s what they told me anyway... :(

Its not them, its N.S screwing us by not giving us warrenty ! and not wanting to import anything to fix these guns! Wolverine is just caught in the middle !

Its a greasy situation all around. parts are obtainable, just takes some time and luck on Ebay, Brp Guns and GunBroker.

I havent spent a dime at Wolverine since this fiasco, As far as im concerned they should be putting a bit more effort in helping us at this point since every single MG34 on this batch has issues due to piss poor QC by TNW.

My TNWs are from over a decade ago from when Marstar was importing them. I just need certain parts that only TNW makes. Tried contacting them directly, and they won’t respond either. They did years ago, but not anymore. Or they just don’t like me.

I’m looking for the new Semi Auto Sear Collar to replace my old style ones.

I figured i would post this picture so everyone can see the difference between the old and new parts (old style on the left). The new style drastically reduces trigger pull weight. Hopefully someone here can hook Desert_fox up.

Yeah. I have the Marstar parts. I’m looking to replace my old style TNW Sear Assembly for the new one on the right of the top pic.

I was out yesterday and put 40 rounds of Russian surplus and 40 rounds of PPU ammo through it.
Toward the end, with every shot, the bolt would lock back behind the feed tray.
I looked to see what might be holding the bolt back but couldn't see anything.
A quick tug of the charging handle was all that was needed to get the bolt to go home.
Any suggestions Greygoose8?
 
Man, you guys are "doing it wrong".

Today I stopped by my range (here is Warsaw, of course) and one of the ROs calls me over to check out the club's "new" MG42! Semi-auto, open-bolt, and converted from full-auto! I see it was also of Yugoslav manufacture and had the Communist Crest on it (just like my K98).

Yes, such guns are perfectly legal to own over here and can be had for about $3,000 Cdn. No TNW closed bolt non-sense over here :D

Did you ever get your revised sear assembly that you were working on perfected?
It looked to be a much better system than what we currently have to deal with
It's good to see you finally post up on here :)

It's possible that maybe the recoil spring is binding a bit. Did you try to remove the metal spacer on the end of the spring and see if it helps?
It could still be dragging against the ejector plate too. You could check it by taking the ejector plate off and paint the underside with a paint pen then put it together and cycle it and see if it's dragging

Also how many rounds total do you have through the gun? They need a good hundred or so to smoothen out
The PPU stuff is good and should work out fine, save your brass and get set up for reloading!
