how do i fix this??

[fd4413]

Here is my bold removed from my m10 and upside down. Can you see the "v" or "u" shaped groove being etched out of the end of the bolt?? How do I fix this? Is this gun not safe to use now?

That groove was designed into the bolt.

Hard to see, but it looks like you need to rotate the extractor back into the groove, carefully.

Did you take the bolt apart? If so, you need to read up on safe reassembly, particularly with that type of extractor groove.

I'll let the experts take it from here, but after you get it back in the groove, close the bolt in the action and with a suitable light if needed, look up inside and ensure that the bolt head lugs are rotating almost 90 degrees to the locked position.

If you check the pics, you see the bolt is correct. The extractor is in the right place. The bolt is pictured upside down.

Looks good to go to me.

You can always check a Mark III Ross bolt with the "Rle of Thumb". There should be just over 1 inch between the front of the bolt-sleeve and the back of the left-rear locking-lug as you insert the bolt into the rifle: enough space to put your thumb across.

The bolt-head can only sit in two positions: 1 inch and well-under-a-quarter inch. Th 1-inch position is correct and, if you think about it, this makes sense: the bolt-sleeve must come forward that final inch in order to rotate the bolt-lugs through their 90-degree turn into their recesses. A quarter-inch just is NOT enough to do this. Only makes sense.

Range time next, I guess! Good luck with the old girl. I am fitting up a couple to go out myself, just as soon as the weather here improves by about 80 degrees F.
