The AA hard use bolts are very well made as well. There is something going on with the coating/surface finish that looks much different than the nitrided bolts.
I think I read the AA hard use bolts are IonBond coated, which is probably a DLC (diamond like carbon) finish. Very cool stuff, my Remington 700 XCR II and a BCM bcg I regrettably let get away, have that finish on them. Very slick and hard stuff. I just bought a VooDoo Innovations bcg that's finished with the same stuff. I'll let you know what I think when it arrives.
