TNothing "inherent" nor "pre-existing" about them.
Again from Cruikshank, this time discussing the right to arms of two former slaves who were disarmed, kidnapped and lynched by the KKK / Night Riders in 1873 Louisiana.
"The right there specified is that of 'bearing arms for a lawful purpose.' This is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence. The second amendment declares that it shall not be infringed; but this, as has been seen, means no more than that it shall not be infringed by Congress."
Just like the right to assemble, the right to arms is not granted by the 2nd Amendment thus "it" is not in any manner dependent on the Constitution for "its" existence. The 2nd Amendment only says that "it" shall not be infringed, it does not create "it" so, the right to arms (the "it") is a right that the people possessed before the Constitution was established thus it is a "pre-existing right".
Might as well look at Presser v Illinois, 116 U.S. 252 , (1886) now.
Presser in discussing the right to arms and the 2nd Amendment, repeated the Cruikshank Court's explanation but it replaced the case specific "bearing arms for a lawful purpose" with the familiar construction of the 2nd Amendment:
" . . . the right of the people to keep and bear arms 'is not a right granted by the constitution. Neither is it in any manner dependent upon that instrument for its existence. The second amendment declares that it shall not be infringed, but this, as has been seen, means no more than that it shall not be infringed by congress."
So, besides stating again that the right to arms is not granted by the 2nd Amendment (and thus pre-exists the Constitution), the Court believes the "right of the people to keep and bear arms" is synonymous with "bearing arms for lawful purpose" as exercised by two former slaves in Grant Parish, Louisiana in 1873 for the purpose of self defense in a state where there was no militia because it had been disbanded by the Governor on orders of Congress . . .
And at this point we might as well flow into DC v Heller . . .
" . . . it has always been widely understood that the Second Amendment , like the First and Fourth Amendments, codified a pre-existing right. The very text of the Second Amendment implicitly recognizes the pre-existence of the right and declares only that it “shall not be infringed.” As we said in United States v. Cruikshank, 92 U. S. 542, 553 (1876) , “[t]his is not a right granted by the Constitution. Neither is it in any manner dependent upon that instrument for its existence. The Second amendment declares that it shall not be infringed … .”
The 1st, 2nd and 4th Amendments codify pre-existing rights, "rights of persons and property which by the Declaration of Independence were affirmed to be unalienable rights".
