Nosler 97231 Muzzle Adapter | 5/8-24

This Nosler muzzle thread adapter provides a direct-thread interface for mounting Gen 1 (non-HUB) Nosler suppressors to firearms with 5/8-24 TPI muzzle threads. It replaces the muzzle brake and permits the suppressor to attach directly to the firearm’s muzzle threads. The adapter is supplied as the standard thread adapter included with several Nosler SR-series suppressors.

Typical applications include range and precision shooting where a direct-thread suppressor mount is required, and hunting setups that use detachable suppressors for noise management and recoil mitigation during field use.
