A barrel adapter screws onto your rifle's threaded muzzle and stays there. It gives the muzzle a mounting interface, so the suppressor attaches to the adapter instead of the bare barrel threads. One adapter per rifle lets you move one suppressor between them. Many are quick-detach designs, and some also work as a muzzle brake or flash hider.
This one fits barrels threaded 1/2x28 and presents the HK 3-Lug interface. A suppressor with a matching HK 3-Lug mount attaches to it. It comes in 2 thread pitches, so pick the one that matches your barrel.
