Yes. If using an AR in any capacity is part of your self/home defense plan in FL, it will be beneficial. And, they're just cool. Maybe if you start showing up at FL ranges with suppressors, it may encourage others to do the same. I guess the gun regs in England are already very strict so almost anyone that wants a suppressor gets to have one easy peasey. Over there it is practically rude to show up without one. They very much value their hearing.
EDIT: As a Floridian, you have access to many thousands of acres of feral hog hunting lands with virtually no limits. A suppressor would be nice to have.
