ALBANY, N.Y. (AP) — A group opposed to New York’s two-year-old gun law says registration data show few owners complied with the requirement to register firearms reclassified as assault weapons.

NY2A, which advocates for Second Amendment rights, says newly reported data show only 23,847 people registered 44,485 firearms while Gov. Andrew Cuomo estimated New Yorkers owned one million such guns before the 2013 measure banned sales in New York.

The registration requirement applies to semi-automatic weapons with a detachable magazine that have a single military-style feature such as a pistol grip.

The group’s co-founder, Jake Palmateer, says data show the gun control scheme was a failure.

Cuomo has called the measures, including a ban on large magazines, common sense.

They were enacted after a gunman killed 20 students and six adults at Sandy Hook Elementary School in Newtown, Connecticut.
