(KRON) — Guns are selling at unprecedented levels.

Background checks conducted by the FBI have hit an all-time high this year.

Background checks do not correlate directly to gun sales, but they do serve as an important indicator since there are no industry figures for gun sales.

Mass shootings in the last several years have helped drive gun sales.

Gun buyers worry that every mass shooting will prompt more restrictive gun control laws.

If Hillary Clinton is elected president, she plans to expand background checks, restrict “military-style assault weapons,” and hold gun dealers and manufacturers accountable for gun violence.
