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 SilencerCo ASR interface. A suppressor with a matching SilencerCo ASR mount attaches to it.

Which ones fit your barrel and host?
See all 612 in the Builder- JK's lightest, smallest and most cost-effective muzzle device for quick attach functionality across ASR-compatible silencers, at 2.2 ounces and 1.0 inch long.
- A front taper protects the threads from carbon fouling and provides a secure, precise mating surface for the silencer.
- Precision machined from heat-treated and black nitrided 17-4 stainless steel.
- Available in 1/2-28 for .22 cal and 9mm, and 5/8x24 or 11/16x24 for .30cal and .45cal; JK calls it ideal for outfitting a safe full of rifles to share suppressors across multiple guns.
