Has anyone seen these? The bolt lugs look rounded(thicker where it contacts the bolt) and the cam pin/hole is smaller?
Looks like a pretty effective way to lengthen the service life of the bolt. Will probably be a while before they sell them individually, if ever… :o
Will it fit into other AR’s by swapping barrel extensions?
The new bolts do look very good. You could use one, but you have to use their barrel extension and I would be surprised if they sell them alone.

I hope to have an SR15 w/ this bolt in hand in the next couple of weeks. You can bet that one of the comparisons I’ll be looking at is the bolt/receiver extension.
Grant is correct, however, that the KAC bolt is not a drop-in for the standard bolt and would require a new barrel/barrel extension.
Awesome! Please keep us posted. This looks very interesting.
