Dave,
I have tested your theory regarding the bayonet on the 590a1 with the heavy barrel and its zero never changed. Have you actually ever handled a 590a1 heavy barrel, I am almost positive that if the knife was not there you could use the barrel as a bludgeoning tool to beat an enemy to death with, it must weaigh the thick end of 3 pounds.
