If I substitute 'abused' or 'disregarded' or 'restrained' for 'enfringed' in the sentence, I see no change in meaning.

The right to own a gun was never questioned.

The first Dutch, English, French and Spanish who came to the New World walked off the boats carrying guns.

The Bill of Rights simply enshrined the right. Restricting it would be an enfringement. That's my take.
