SilencerCo AC1361 Thread Protector 45 ACP Black Steel .578″ x 28 AR-Platform

When transporting your firearm, keep your threads crisp and protected with a thread protector. Careful not to cross-thread, simply twist the thread protector on the end of your barrel to prevent dust and debris from clogging your threads when no silencer is in use. .578" X 28 is compatible with most US-made 45ACP.
