I have a Surefire FA556-212 with 2 mounts I would sell reasonably cheap. Right around 100 rounds through it, FDE. Badass suppressor IMO but it IS an older model Surefire so the mounts are a little hard to find.
I'll be at the Tanger Outlet exit this coming Saturday at 10am if you want me to bring it and take a look at it.
I no longer own any AR's so I have no need for the suppressor anymore.
Define “relatively cheap”.
