Why the comma before "being" in the Congress Version - 3

Another way to express that is to say:

The comma-less before "being" version of the amendment more clearly makes "being necessary to the security of a free state" a condition on a militia.The comma before "being" version of the amendment shows how looking for the satisfaction of that condition should be done. It does that through the use of the comma before "being". This comma changes the "being necessary to the security of a free state" from a condition to a fact. The generality that comes from stating "being necessary to the security of a free state" as a fact in comparison with stating it as a condition was not intended for the purpose of stating that it remains continuously true regardless of reality changes. On the contrary, the word "being" directly points only to the applicability of what it states in the current time. No, that generality is the result of an intention to state the origin of what makes a militia being "necessary to the security of a free state" is the general environment at the time and not the militia itself as long as it is "well regulated".
