Re: MG blew up in my face! Need help

I am asking for measurements, if you can measure your good working Yugo barrel that will help me a lot. There is a reason why this forum is kind of dead, people get told to use search all the time then why even bother posting anything anymore, everything has been discussed. When I was training with ...

I asked for few measurements and you don't want to do it. My hands are tied

Can anybody give me this measurement of your Yugo barrel?

Re: MG blew up in my face! Need help

As I too have said before, messerschmittfan is absolutely correct. This problems is caused by the back of the chamber being drilled out and missing. I am not talking about MG3 barrel anymore, I am talking about my green mountain 8mm barrel that has identical chamber to my original Yugo, so that is ...

Re: MG blew up in my face! Need help

You're shooting a rimless cartridge, and measuring headspace with the rimmed cartridge method. It doesn't work that way. Really? You are treating me as a noob but you forgot that I joined this forum only one year after you. So I have been around. I have successfully built and headspaced two Yugo M7...

Re: MG blew up in my face! Need help

If it's too much trouble for you to look for it when you're the one who wants the information, then it's too much trouble for me to find it for you. I don't care to read a bunch of stuff about headspace just to be able to find what YOU want, when you won't do it for yourself. I did search, but unde...

Re: MG blew up in my face! Need help

On my 8mm green mountain barrel, checking headspace visually. I removed the extractor and with bolt facing down on the barrel I get no visual clearance with rollers fully locked up, when I turn the barrel around now bolt hangs down there is a 0.5mm gap and I can see the light, rollers are still lock...

Mine ended up about 1/4 in. short and functions flawlessly. Was having issues until I changed to good ammo. Shorter will likely only require less gas presser to operate, not that one should stray from proven blueprints.


Only bad 8mm ammo out there is 80s Yugo brass?

Re: MG blew up in my face! Need help

I was talking about the recuperator's head vs recuperator tube, (the recup itself) not the barrel and its relation to the recuperator. I was talking about recup head vs recup tube. Booth of mine do compress to the end, it will appear that it stops about 5mm to the end but if I put my whole weight b...

Re: MG blew up in my face! Need help

8mm shells look near ready to blow. Did you check headspace? I checked it face of the bolt to the barrel has 0.5mm clearance with rollers fully locked, the same as my old yugo. If headspace was bad then it would show on first 10 rounds? Do you have automotive feeler gauges? Can you take your best b...

Re: MG blew up in my face! Need help

That sounds about right...recups of all types including the MG3, the head does not fully compress flush with the tube. The question on them always is if the spring rate is still in spec. According to the manual it should be flush and barrel should be stopped by the cam and not the recuperator. http...

Glad you are OK BTW.


Also I got two recuperators, both Yugo and they don't compress flush, the plunger stops with about 5mm still to go.

Re: MG blew up in my face! Need help

messerschmittfan is absolutely correct. With that much of the chamber missing, I'm surprised the first three shots didn't blow too. Looks like that barrel is scrap. Where did you get it? At the gun show. The cut seems to be factory, have you ever seen mg3 barrel like that? What is your opinion on m...

MG blew up in my face! Need help

I bought all of the parts to get my M53 semi shooting 308. I also bought some new german 7.62 ammo. 3 rounds barely held the pressure and 4th one blew up, blew open the breech door and busted out extractor from the bolt, I felt the pressure against my face, good that I wear protection. Now what is g...

I'm only stating what nozzles I've got in the 1/2 dozen or so Yugo kits I've bought over the years, plus many nozzles and parts I've bought separately. . thanks for the information. Can you post a photo of your Yugo springs. I want to count the coils. Have you seen different size barrel bushings fo...

Re: Pricing of semi MG/M53 now in 2017?

I also have about 6 Yugo booster nozzles ranging from 10mm, 11mm, 11.5 (most common),12mm 13mm and 14mm. Sizes (gas) can be used to tune the gun for ammo variances, but in the field I assume varied sizes were for temps (freezing) tightness of gun, dirt, etc. Yugo gunner's 256 page field manual does...

Re: Pricing of semi MG/M53 now in 2017?

The recoil spring Is supposed to reach from the rear of the receiver to the front edge of the feed tray, according to the manual. It does not make any sense. Springs measure around 16 to 17 inches and from rear of the receiver to the front feed tray is about 14.5 inches. Give me exact measurements ...

Re: Pricing of semi MG/M53 now in 2017?

do you have the metric specs of the MG42 receiver? I can't seem to find solid answer. What main spring lengths are out there?
