Is LMT the only company who produces bolts with an "undercut" behind the bolt lugs as pointed out in the picture?? Or does someone else do this as well??? I have heard this "recess" increases reliability.
Please note, this is a picture that someone else posted on a seperate thread and I am just using it because it shows the angle that I want.

I'm 90% sure LMT is the only one who undercuts their bolts

well. I can see where not having a lug break off could be considered a reliability enhancement

I just received my BCM M-16 bolt assembly today. The carrier key is not MIM and the staking is perfect with no cracks. Thank god, since I usually have bad luck in these issues.
