I'm not the one needing the work done, codybrown is. He said his rifle was a 220 Swift.Edd, You got it right. However, you didn't say what size face your bolt has. I don't install M-16 style on 223 size cases because to mill deep enough, you either get into the firing pin channel or very close to it. I have heard of a couple that do. most, like me, don't.
However, I do have a 223 bolt with a mini 16 extractor but it is a Defiance action.
