Californians Will Have To Register Made-At-Home Guns

People who build their own firearms will have to get a serial number for them from the state Department of Justice, under a new law. Governor Jerry Brown Friday signed the final of several firearms restrictions state lawmakers passed last month.

The bill’s proponents say it’s too easy right now to order unfinished rifle frames and build guns at home, creating untraceable firearms.

Also, as 3-D printing evolves, gun control advocates worry it will be easier to create unregistered guns at home. Opponents say the new law will infringe on an American tradition of manufacturing personal firearms.

Last month Brown vetoed a more expansive bill that sought to regulate so-called “ghost guns”— it would have reclassified various firearms parts, as guns themselves. Brown called it vague.
