Fact-check: Does the Second Amendment place limits on individual ownership of cannons?

Joe Biden: “You couldn’t buy a cannon when, in fact, the Second Amendment passed."

PolitiFact's ruling: False

Here's why: President Joe Biden announced new regulations to curb the proliferation of so-called "ghost guns," unserialized firearms made from kits.
Biden spoke of codifying a prohibition on manufacturing these firearms without serial numbers, requiring sellers to conduct a background check on prospective buyers, among other rules. He also detailed his desire to see assault weapons and high-capacity magazines banned.

Then the president invoked history to support his stance. 

"From the very beginning, the Second Amendment didn’t say you can own any gun you want, big as you want," Biden said at the press conference. "You couldn’t buy a cannon when, in fact, the Second Amendment passed."
