Shoot and enjoy it until it stops working . In the mean time keep looking .

 

Agree with @swede - unless you are missing the springs - keep shooting until theres an issue - if you desperately want to get spare springs you can get them here - Recoilspring Ag m/42 New

Thank you very much!

 

I don't think it was issued after it was refurbed. there are no wear marks in the receiver. Bore measures at 6.48.

 

I recommend installing the home-made gas block regulator. You will need an M4 x.5 screw and nut. M4x .5 is hard to find since M4 x .7 is the common size. "Swede" has some M4 x .5 lock nuts.

 

They are not lock nuts . Just a plain plated nut . Had a bag of 25 , but all gone now . Sorry !

Oops! The nut is used to lock the gas port screw in place.

Wow! Looks like there are more AG42b shooters out there than I imagined.

 

or do something like this - https://www.gunboards.com/threads/ag42b-gas-port.1236643/

 

That's very slick!

I'd be interested in that but I don't have the tools for that. if you have any extra I'd be interested.

 

If/when you get your 12 mm screw and nut, remove the cap screw on the top of the gas block. If it resists, don't force it or you'll cheese the slot. Give it a good soak overnight with penetrating oil if needed.

Straighten out a paper clip and put a slight bend at the tip. Insert this into the hole and feel for the opening of the gas tube. Mark that on the paper clip, or just bend it. That is your reference for the screw adjustment.
Start adjusting the screw to just above the top of the gas tube opening, then test fire with 1/2 turns until the ejected brass lands where you want it. You don't want to block the gas tube too much because hand ejecting a fired round can be a bitch. Bring along a piece of 2x4 and a rawhide mallet to the range. If you need to, give the clip guide a swat.

 

The gas screw is staked in place . So , make sure you use a hollow ground gunsmiths screw driver blade to avoid buggering up the slot . You need to have the rifle on a solid bench and use a lot of downward pressure to turn the screw .

 

Thanks!

I really need some of those anyhow, so I don't bugger up other things.

 

Midway has a set of Chapman Gunsmith screwdriver blades for $45 . Some with more blades . Price is up to you . I did find out that the rolling block screws have a much narrow slot than most screws and I had to thin the blades on some just to be able to disassemble a Swedish rolling block . You can search the internet for many brands & number of blades to suit your needs .

Thanks Swede!

 

I ordered some hardware and will have some extra m4 x 0.5 nuts if anyone was in need, should be here within a few days.
