Maybe someone more familiar with the mechanics of the forum could make a poll out of this.
1: I would never buy a silencer, they're dumb.
2: I would buy one if they were like buying a handgun, background check, etc,
3: I would buy one only if they were sold as an accessory, like grips, or a sling and I could get it mail order.
4: I already own one and have gone through the NFA paper chase.
