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 5/8x24 and presents the CAT 1x16LH QD interface. A suppressor with a matching CAT 1x16LH QD mount attaches to it.
