No worries! I think the common observation is very tight gas rings, which I acknowledged and others have verified. My observation was that my extractor does not look like all others I have seen; as the image clearly shows the spring end of the extractor is not flush with the rest of the bolt. Anything to worry about? Uncertain. Should everyone be aware? definitely!
I think I figured out why your seeing it the way you do. How many Grendel bolts have you looked real close at? I'm being sarcastic because I just realized that what your seeing is correct and the head space being .010 deeper lets the extractor close further toward the center of the bolt letting the extractor heal stick out. I never looked so close but I think that is what your noticing. So your not crazy, its a GRENDEL thing....
I just compared an AR-Stoner (used one in my Grendel), a new Maxium and new LBC Bolt. All the measuremnts work out so that is what I'm seeing.
I also measured the OAL of the Grendel bolts and a 223, the Grendels are 2.810 and the 223/556 are 2.800. As it was brought up in the past, they added .010 to the OAL of the Grendel Bolts for the firing pin protrusion.
