Our very own Phil Watson testified against these bills in committee, particularly the "bump stock" ban:

"A modification of a trigger itself to shoot fully automatic is already illegal," testified Phil Watson, of the Firearms Policy Coalition.

Via King 5 News:

Hundreds of people crowded in Olympia on Monday, gathering in the Senate building for the legislative hearing on several gun safety bills.

The bump-stock ban was one five gun safety bills discussed Monday. Others included SB-5463, regarding safe storage of firearms, and SB-6049 which would prohibit magazines holding more than ten rounds. SB-5444 would require enhanced background checks on assault weapons, and SB-6146 would allow local authorities to regulate firearms in their communities.

Gun rights advocates argued a ban would have little impact.

"A modification of a trigger itself to shoot fully automatic is already illegal," testified Phil Watson, of the Firearms Policy Coalition.

"I'm fairly involved in the firearms community," said William Burress, of the Gun Owners Action League. "I know two people in the state that have them."
