Given that I'd never been to a buyback before, but heard about them, I was still expecting to to see some people my age or younger and I did not and I did not get the feeling that any of the people I saw in line were guys that had done a drive by shooting with their bolt action Mosin or break action shotgun.
Had I seen Crips and Bloods handing over their 9mms, I was going to say that everything I'd heard about buybacks was BS... but I saw exactly what I've read and heard about them. The belief that gangbangers are gonna wake up at 8 AM to go to a buyback for gift cards is stupid, they're not. If they've got a piece that they used two weeks ago during a robbery or an assault, they either throw the thing in a river or they sell/trade it for something else.
Sten gun guy, if it was real (it looked it), he said that he had put a bead of weld to make it inoperable, it may have been put there years back, but if I was in his shoes... I wouldn't take the chance of a 10 year prison sentence holding onto that for a second longer than necessary. Not for a Sten gun where parts availability and reliability are questionable. Seriously, there's nothing about a Sten gun that makes it worth the felony that a 9mm AR with a binary trigger that uses Glock mags can't do.
I guess you could call it that, but what I handed over was something I bought never intending to do a buyback with. Manipulating the buybacks would be me buying guns that I intend to use for a buyback and make a profit off them whilst also shooting them to have the experience of shooting them.
