How do they function and did TNW do a good job on the semi-auto conversion parts? I guess what I really want to know is did TNW detract at all from the gun long term reliability by not engineering the semi-auto conversion parts as good, and at the same quality level as the original design?

I really want to avoid buying a gun that I have to struggle to get 10 rounds fired w/o a jam, or that I have to keep sending back to the manufacture to get stuff fixed.

Someone else will have to comment on TNW's complete SA MG34's but you can look at the quality of their receiver at the following link:

Your Question is worded perfectly.I have a US Ordnance 1919A6,Vector Arms RPD,BRP MG42SA and the TNW MG34SA.

THe TNW gun is beautifully made but mine has been one trouble after another since I got it. I blame it on how they designed the Semi-auto conversion and poor quality control in welds in the rear bolt section.If you are willing to live through troubleshooting potential problems you will end up with a nice piece.Just my expierience.You may get a great one out of the box.

My 1919 and RPD have been perfect from day one.The MG42 took a little breaking in and finding the belts it likes.

Yours has welds in the rear bolt section? The only welds I see on my TNW bolt is where they filled in the slot for the FA sear.

My firing pin is one piece as well. Have you tried any of your one piece pins?

Overall my gun has had issues too. Here are the things I have had to fix.

1. Feed cover TNW installed was too loose; it caused feeding jams. I have replaced the cover and it feeds fine.

2. The sear wore out causing it to either fire bursts or simply not stay cocked after the first trigger pull. I replaced that and it works good.

3. The small screws to the ejector plate both broke off in the receiver. I managed to get them out and have replaced them both.

4. The front half of my bolt had a breakage near the firing pin retainer.

I never expected this gun to work forever and not have any breakdowns. So the above issues have not ruined my fun level with this gun. I got it in 2002 so my one year warranty expired long ago. All these troubles I have fixed myself. That has been part of the fun.

Thanks for the respnses guys.


Please excuse me while I post a few more times in this thread so I can get to my 5 posts, so I can see some of the other posts on this board.

Who made your semi-MG42? Are you happy with it?

BRP made my MG42SA. I am very happy with it. Once I broke it in a little and realized its preferance for WW2 dated belts in has run great.

My post above about the MG34 welds.The ring that holds the sear assembly in the back of the bolt is welded in. The welds failed and the ring moved,putting the sear assembly out of adjustment.Ring moves forward,firing pin doesn't cock.You would think it would slam fire but instead it throws off the feed cycle somehow and the gun stops running.First time I sent the bolt back they replaced the sear.When it happened again I was the one who noticed the sear retainer ring that was welded inside the bolt had moved. TNW replaced the back half and its been fine since.
