A trigger pack AND a full auto style bolt can enable an H & K semi receiver to fire full auto. The term "registered" needs to be defined. You're using it to include "research" parts made by an SOT, while most people use it as meaning that it is a transferable item, that is, a...

Salt6 lives! Welcome home, friend.

Conversely to the above possibility, it could have been a registered machine gun, and the guy made a semi auto kit that works in the MG receiver. It's perfectly legal to do that, just not the other way around.

A few drops of oil at the pivot points should prevent the trigger group from sticking for years. Glad to hear that all is well.

Someone on ebay.de was selling them several months ago. I suggest you check there.

Picture 3 is a combination tool for ruptured case extraction and extractor changing. I think the tool above it in picture 5 with the handle and L shaped is used to compress the spring for assembling the rear sight. L shaped tool in picture 1 is a bore/chamber mirror. Picture 6 - front sight adjustme...

If someone has the manual (TDV 4933/022-12), I know someone who could translate it.

The charging handle bar is indeed supposed to be straight. Of course, when the bolt is pulled fully rearward, it is caught by the sear in the trigger group. You'll need to look there for the cause of the problem. Of the two tabs that protrude downward from the bolt body, the rearward tab is caught b...

take off the buttstock, buffer and recoil spring, then remove the trigger group and take out the bolt if it will come out. You may have to manipulate the charging handle to get the bolt out. I'm guessing the charging handle is in crooked.

The "rail" with the hooked end that you are seeing is part of the charging handle. It's not in the position it is supposed to be in for a functioning gun. I'm not familiar with UK rules for deactivating guns, so I can't say whether or how your gun should function. The safety won't operate ...

The single best MG42 manual I have would be HDv 241. Each has some details not covered in the other manuals, but for an operator manual, HDv 241 is tops. It covers all the basics that the shooter needs to know.

At my local paint shop, the device they put the color chip into is smaller than a microwave oven. I doubt they'd have something big enough to put the twin mount in.

I'd suggest cleaning the chamber of one of the problem barrels. Put a stainless steel bore brush on a rod, put the rod in an electric drill, and run it in and out for 30 seconds or so while squirting some bore cleaner on it. The shell might be sticking in the chamber causing it to pull apart. I had ...

take a paint chip to the paint store and have them put it in their machine to match it.

Barrels get the headspace checked with each bolt. Check each barrel with every bolt you have. Is that what you did?

Wow, that's a very broad subject. There is likely not a definitive single answer to this question.

It is not legal in the US to have an open bolt semi-auto gun (except for some that were made years ago), but if your laws allow it, the MG42 would be a pretty simple trigger group to convert to single shot from an open bolt. The problem I see is that it would be too easy to convert to full auto, unl...

The firing pin should not protrude from the bolt face when the firing pin is fully rearward. If it does, that's a good place to start for fixing things. Excess protrusion causes blown primers, so you need to check the protrusion. Protrusion should be between 1.35 and 1.65 mm.
