No, they go well past what's regulated. Well past. It's not a legal thing, it's an anti thing and it was done in response to Virginia Tech.Good lord.
Y'all know eBay owns Paypal right? I won't rehash the reasons eBay stopped allowing gun sales, and other items that have some sort or federal regulations, because that's too easy to find for yourself (look past the rumors and no-truths) but look at eBay.
Anyone ever heard of Bob Serva? Fusion? (ex-CEO of Dan Wesson) He sells a ton of parts on eBay. Yo can find a ton of of items that are not subject to any regulation on eBay. And you can pay with Paypal. I've done it many times. There are also several holster makers that ise eBay as a primary retail channel (can't say quality makers, but......) as well as a ton of folks just selling stuff.
I've never tried to break their policy in regards to restricted items, but then again, I have no reason to.
The only thing they are "anti" is legal action so they made a decision....a long long time ago.
Do you know they also prohibit the sale of breast milk? I'm sure that will jog some memories of this same topic from days gone by.
