LANSING, Mich. (AP) — Michigan lawmakers are passing legislation intended to loosen regulations on BB and pellet guns.

The National Rifle Association says Michigan has outdated and “unduly burdensome” restraints on the purchase and possession of most air guns. Backers of an eight-bill package say it would bring Michigan in line with federal standards.

The legislation would redefine the term “firearm” to exclude guns that propel a projectile by gas, spring or air.

One bill approved 102-6 by the House Wednesday would repeal a law making it a misdemeanor for a minor to possess a BB gun unless accompanied by an adult. A Senate-passed bill pending in the House would generally prohibit local governments from regulating ownership of paintball and BB guns.

Municipalities could limit their use to authorized locations or on private property.
