Are the piston rod assembly & piston identical on the MR556 and MR762?
For the life of me, I can't see a difference. And they appear to fit as well...I've swapped one from a MR556 to a MR762, and vice versa. Are the part numbers the same? HK Parts lists the MR556 piston rod assembly, but doesn't list one for the MR762. Thanks in advance.
