No sense in getting the NiB if I'm just going to lap off the NiB in order to "square" the bolt, and insure maximum contact on the lugs, IMHO. Was wondering what anyone else thinks about it?
I would think it would be counterproductive to spend money on a NiB bolt and lap the finish away. I saw a picture of an HK 416 bolt, it looked to be completely deburred, and polished, much the same way a custom 1911 pistol would be. I have an extra bolt that I plan on trying that with. I bet that kind of detail work helps to eliminate stress risers and makes for a very smooth cycling action.
