Establishing state standards for the labeling of imitation firearms sold inside Washington state.

SB 5735 defines "assault weapons" in Washington state through specific firearm models (like AK-47s, AR-15s) and features (such as detachable magazines, folding stocks, or certain grips). It affects firearm sellers, manufacturers, and law enforcement by establishing clear criteria to identify regulated weapons under state law. The bill amends existing statutes to include detailed lists of prohibited firearms and features, such as rifles with magazines holding over 10 rounds or pistols with threaded barrels. These definitions determine which firearms are subject to Washington's assault weapon regulations, directly impacting sales and possession rules. The bill does not address labeling requirements, as its focus is solely on defining regulated firearms through specific models and features.
