CA Compliance:
California compliance
- Status: Legal to own in California.
- Configuration: Fixed magazine (CompMag), installed by WBT. The CompMag is a fixed 10-round magazine that stays in the rifle and loads one round at a time from the side through a loading port, so the rifle keeps its pistol grip, stock and muzzle device and is never opened to reload. It fits most rifles that take a standard AR-15, AR-10 or AK-47 magazine.
- Magazine: 10-round CompMag, fixed in place; loads from the side.
- Your options: This is the one configuration that works for this rifle; it is not offered the other way.
