For a 30lb rifle, the Barrett .50 cal is one awesome weapon! Can disable cars, and turn a terrorist into a two piece terrorist at over a mile. Ooh rah!
And as for the Chicago area mob attacks, they will stop when someone 5X's some of these little scumbags! I wouldn't want to be the unlucky one who gets put in that situation, but none the less, it will stop when people start shooting these evil little bastardos.
