Help with Broken Bolt Damaged Receiver M1 Carbine

[a1parrothead]

Painter777,

I looked at the diagram on page 76. I cannot quiet tell what I am seeing in the area where my damage is, but I can certainly see mine is chipped/broken. I have posted picture again with arrow pointing to the damage and my main concern.

Also, I looked at the picture you posted of the other guys broken receiver. Yes, that is where mine broke exactly, though not quite as deep of a chip. I read his old thread and it sounds like I am in deep doo doo.

Also, Sounds like its not a repairable area per CMP and Fulton.

Is that your impression of the damage? I guess I am grasping at straws hoping this can be repaired. No way I can afford a replacement receiver and bolt. No way. If it cannot be repaired the things a paper weight!

Jeff, Here are (2) pictures of my Underwood receiver. I was concentrating more on the RH locking area, which I thought looked "odd" on your picture. The LH side on mine looks marred up a bit, too. Hope this helps. - Bob

Bob,

I see what you saw on the right side of my receiver. I have inspected that area and am sure its just a scratch.

Look at the picture I posted above with the arrow. There is a CHUNK taken out of the left side of mine.

Thanks for posting the pictures.

Jeff, Make sure you read those other two links I PM'd you with. Good info in there. - Bob

I believe it probably can be repaired if you can find someone who does micro laser welding. Which can be used since it does not use a lot of heat to get the weld to hold in critical areas of the receiver. The damaged areas can be built up and machined down. I of course would proof test the carbine before any continued use. I hope everything works out.

Are M-1 carbine bolts "drop in"?
I seem to remember that they are not "drop in".
Any feedback appreciated.

They are to the point they'll work but all should be headspace checked.

Yes the receiver is damaged and it may have been the cause of the bolt letting go. The left lug is supposed to lift up but the damage to the receiver can catch it and prevent it from lifting in proper timing. The extra strain is now on the right hand lug and the lug fail at the weakest point the area of the extractor. If you were to replace the bolt now and continue to shoot it the new bolt is bound to break too. That is why you have to fix it first. Good luck with it.

Thanks for all the replies. I am talking with several qualified gunsmiths to determine if it can be safely repaired.
