Thread adapter
The thread adapter is mounted and fixed directly to the thread of the weapon. Before mounting the thread adapter, always check the thread on the rifle and clean it from grease and dirt. Also check that the thread in the silencer and the thread adapter has the same thread.

After cleaning the rifle thread, thread locking is applied to the thread (e.g: Loctite 243).

Install the thread adapter on the thread of the rifle with thread locking and use a 21mm block wrench, socket wrench or other to ensure that the thread adapter is properly mounted.

Wait until the thread lock has hardened before mounting the silencer on the thread adapter.

When the thread lock is hardened, the mounting of the adapter is done and the rifle thread is now converted to M18x1.
