True, in fact only some parts of the BoR have been extended to the states.
F.ex.
Freedom of speech - Giltow v. New York (1925)
Right to counsel in capital cases - Powell v. Alabama (1932)
Establisment of religon - Everson v. Board of Education (1947)
The exclusionary rule - Mapp v. Ohio (1961)
Right to counsel in all cases - Gideon v. Wainwright (1963)
Trial by jury - Duncan v. Lousiana (1968)
Some parts of the BoR (like the 2nd Amendment) were never extended to the states and some parts of the BoR (like the Sixth Amendment's implicit guarantee that convictions be obtained only from unanimous twelve-member juries - the Supreme Court held that juries had to be composed of twelve persons and that verdicts had to be unanimous,because it was customary in England) were explicitly limited to the federal government (Burch v. Louisiana in 1979).
The 2A is a right of the people period as the plain language of the BOR's attests. Who do you suppose "the People" are?
