You could be right, and I could be wrong. But the bolt handle is clearly one piece with the portion of the bolt its attached to; they weren't two separate pieces brazed together, like the Remington 700. They are cast together. Now, it could be that there are two bolt sections brazed together, one piece with the handle on it. If that's the case, and I admit it could be, Winchester is doing a phenomenal job. I looked at all 4 bolts under a 90X jewelers glass and there is not the slightest hint of a gap/joint between pieces, or the 'overflow' of brazing material, which is visible on brazed joints on Remington 700s. They are perfectly mated together. As you know, the Remington 700 bolt is a three piece bolt. The head is brazed on, too. On all of my 700s, while there are no gaps between pieces, joints are evident. There is brazing material visible at the joints of the parts brazed together.

So, if I added to any misunderstanding, I apologize. I wanted to point out that the handle and the bolt are one piece (unlike the 700) but concede what I meant may not be what someone else meant by one piece. I think it's clear to anyone, though, that the design is very superior to the 700 design, and any fears that the bolt handle is somehow a weak link in the design is unfounded.
