On the flipside, they'll take ammo I discovered.....same bro has been stockpiling weapons and ammunition and wanted some hollow point .380 - I found two boxes at a local (California) sporting goods store and snapped 'em up; I hadn't bought any ammunition for years and fully expected to have to produce ID...didn't happen.
Bro simply mailed me a UPS shipping label, I slapped it on the box, and dropped it off.
