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 KAC QDC interface. A suppressor with a matching KAC QDC mount attaches to it.

Which ones fit your barrel and host?
See all 6 in the Builder- Designed as a mounting interface for KAC 5.56mm QDC suppressors when used in conjunction with shrouds on barrel/handguard combinations requiring additional clearance.
- Without a suppressor mounted, the 5.56mm Open Brake reduces felt recoil and muzzle lift.
- As a suppressor host, it will reduce wear to the first baffle and extend service life of the suppressor.
