I did get the nose pieces swapped and that nearly eliminates the bind. There's still a little when I remove the recoil spring and slide the bolt all the what to the rear, but not enough to cause malfunction. I had a very successful outing with the MG42 SA and my father the other weekend. We put arou...

The damn stickies! I read through them a few years ago but had forgotten all about them. Thanks for the reminder...very helpful. According to the sticky, the other two buffers don't have the groove cut near the threads like the German buffer one I posted above does. The German one also has a bit lar...

I'll buy that. Your pic shows nice clean dents or caving in. The case on the right in his pic looks like it was crushed head on, sort of like it didn't clear the ejection port and the bolt ran into it or rammed it into the ejection port.

That is a Steyr butt stock. Pardon my lack of knowledge, but what marking is this on the buffer? Is that a Yugo mark? 20180729_160211.jpg If so, what do you mean that the Yugo buffer won't fit the stock? It assembles just fine. I have two other buffer and butts in various parts kits laying around. T...

That's a significant taper! Not that I've seen a lot of semi converted MG42's, but mine doesn't have that much length ahead of the spring. I suppose I could reduce the diameter a little, but I'd rather leave it original if possible. And is that end piece of my buffer thru hard or case hard? I think ...

Another mostly successful day at the range. Fired ~50 rounds between two different ammunitions and it behaved near perfect. I did have two F2eject. This was caused by binding between the bolt carrier extension and buffer. It seems that I have excess clearance allowing for some rocking of the buffer....

High speed photography would solve this question immediately. Try putting a rubber pad (piece of radiator hose or similar) on the front of the trigger guard to see if the brass is twirling into it upon ejection. That's what it was on mine, the rubber pad worked well. I also had the bolt moving pret...

Thanks for that link robertmcw. I've been there several times in my various searches working on this project and didn't notice that was the grip stick. It definitely doesn't work with the original safety or panels as it sits. I'll have to see if I can modify it to accept a safety. I really don't wan...

I have not tried a different recoil spring but I'll see if I have another one for SA. I guess I was worried about the excess speed because, like you mentioned, most MG42 SA rifles have the opposite and I don't want it to beat itself up. Would a worn recuperator allow excess bolt speed? Mine takes ab...

Getting closer. I don't get to spend a lot of time on this project. To clarify, I've actually spent a lot of time on it, just much time consecutively, more like a day or two this month and a day or two the next month. I got some good advice from BRP in that my bolt is running too fast. He gave two o...

Are there any reasons this wouldn't work in semiauto? Have you done any testing in a semiauto 42?

What about shimming the barrel extension to increase chamber length or machining the barrel's shoulder shorter to decrease chamber length to make it headspace with the various bolt heads?

I was somewhat surprised to see some bulk Wolf and Tula 8mm and even 308 that is relatively cheap. Over the years I have seen posts speaking badly about some ammo and I just want to make sure that what I shoot is worthy of my 42. I appreciate any thoughts in finding the best and cheapest ammo for f...

Thanks for the tips on the ammo. I will steer clear of the Tula...probably in all firearms, it's not worth it. The extractor seems fine for now, I pulled it and cleaned it really well. I used a small vice grip to compress the keeper out of the way, seems to work well. I dug out another 8mm barrel wh...

Pretty quiet around here. I checked headspace on the 7.62 x 51 barrel using .308 gauges. It checks good...the go gauge goes, the nogo gauge does not. The 8mm is a different story. The nogo and field gauges both go in all three of my bolts. In fact, the field gauge goes with an additional .012" ...

Did you figure out what's going on yet? If not, is the FCG brand new? With your gripstick out and starting with the hammer forward and finger off the trigger, slowly move the hammer back and watch the two surfaces indicated in the pic as they pass each other. Do they touch or is there a gap? The gap...

Hammer follow arrears to be solved! This was the best outing with the semi MG42 to date. Not perfect, but got to run through a few different ammunitions and really begin to see how much a role ammo can play in reliability and safety. From my last outing, I found another firing pin laying around that...

Heading to the range tomorrow for another round. As far as 8mm ammo, all I've got is current production PPU (which I'm beginning to think has thin brass and soft primers) and a case of Turkish ammo. I plan on trying some of both tomorrow even though the Turkish is said to be a no-no. I do have the p...

I reworked the bolt by welding a plate on the bottom towards the front of the bolt carrier and filing down the bump at the rear. The result is that the hammer, when held by the disconnector, only touches the bolt where this plate is, and has a lot more time to float and settle on the underside of th...
