The "assault weapon" ban that was unanimously approved by the Boulder City Council this week is a model of simplicity compared to other legislative offerings of this genre. The federal ban proposed by Sen. Dianne Feinstein (D-Calif.), for example, lists six forbidden rifle features, "157 dangerous military-style assault weapons," and "2,258 legitimate hunting and sporting rifles." Boulder's ordinance does away with the bewildering gun catalogs and focuses on three rifle features:

1. a pistol grip or thumbhole stock

2. a folding or telescoping stock

3. any protruding grip or other device to allow the weapon to be stabilized with the non-trigger hand

The ban covers semi-automatic rifles that accept detachable magazines and have one or more of those features. Anyone who already possesses a newly prohibited firearm has until the end of the year to register it, surrender it, destroy it, or move it outside the city limits.
