Mack Brothers Zenith 1/2″–28 Breech End
The Zenith 1/2″–28 Breech End is designed to give your suppressor added mounting versatility across platforms with smaller thread pitches. This component seamlessly replaces the standard 5/8″–24 breech end that Zenith suppressors are supplied with, allowing you to properly and securely install your suppressor onto rifles threaded at 1/2″–28.
Precision-machined for proper alignment and repeatable performance, this breech end maintains the durability and concentricity required for safe, reliable operation.
Compatible with all Zenith series suppressors EXCEPT the Zenith 45.
All parts proudly made in the USA.
