Up for sale I've got an AAC Blackout 51T flash hider. This came off of an AAC factory upper that appears to have never been shot, so muzzle device is in great condition and appears to have never been used. This muzzle device is threaded for 5/8x24, which is standard for most all 308/6.5 rifles. $74 shipped to your door. Let me know if you want it.
