6.8 SPC bolt from 223/5.56 bolt
#6
One of the overarching concerns would be the removal of surface hardened material. These bolts are heat treated, and grinding / milling / cutting will only compromise the surfaces in one of the areas where hardness is most needed.

Is it really worth the cost of a new bolt to see if you can do this? I'm not familiar with your machinist skills, bj139, but even if you are successful in hogging out the bolt face, are you certain you want a compromised bolt?

ETA:

If you're really convinced this is something you want to try, at least follow the lead of people's opinions you might better respect.

If it's true that we are here to help others, then what exactly are the others here for?
