"Use it however you like,so long as its safe and you aren't commiting crimes"
Trouble is, they can't say that. And if you use it as a stock, you ARE committing a crime. Unless you have prior ATF approval.
and here's another point to consider, about defending yourself from a mob,
WHO do you shoot? Who are you JUSTIFIED shooting?? I don't know if we have established legal guidelines about shooting a mob other than you can't...
You can be justified shooting to defend your self from an immediate threat. Now, which ones of the mob are such a threat? The guy throwing a brick? Probably, deadly weapon, etc. The guy with the molotov cocktail? I'd say so. The guy with a club 30 feet away??? not so much..the guy with no weapon yelling threats, standing next to the guy with the brick?? doubt he's an immediate threat,
Can't think of anyone a prosecutor would more like to send to prison than the "right wing gun nut" who "took the law into his own hands" and sprayed the "mostly peacful" protesters with his "assault weapon" causing multiple injuries and deaths...
You DON'T want to be that guy....
Of course, if you're no longer alive, court rulings against you are of little concern...
