Those 2 are within tolerances. The problem comes when they are 0.011 +/- apart.
The carrier itself is "agnostic", doesn't care what bolt you use; like A5 says the bolt and firing pin are what has been an issue.
IF you have a *short bolt+short pin* or whatever from toolcraft they will work ok as long as they are kept together (pin and bolt).
I hope I haven't mixed any of this up... several threads on those TC bolts and firing pins.
The longer bolt for the grendel is to allow use of the standard firing pin but allow for the 0.136" (extra 0.011) depth of the bolt face.
