Thread protector - Griffin Armament Thread Protector for Taper Mount Muzzle Device

I just resentlly purchased a Griffin Armament Tapered mount Flash suppressor, 1 of 3, for my AR-15. I purchased the Griffin Armament Threaded protector to protect the threads, it works great. I have a Griffin Armament micro suppressor. I use it when I take off my suppressor to protect the thread from getting scratched and marred. Like I said it works great.
