Advanced Armament Corp Adapter 1.375x24 to 5/8x24 Thread – Direct Thread Mount for AAC Suppressors

This AAC thread adapter converts a barrel with 5/8x24 threading to accept suppressors with 1.375x24 direct thread mounts. Designed for shooters who want to use AAC suppressors on rifles originally threaded for standard 5/8x24 muzzle devices, this adapter provides a secure, concentric mounting solution without permanent modification to the host firearm.

Machined from steel with a black finish, the adapter installs onto the barrel's existing 5/8x24 threads and presents a 1.375x24 male thread for direct attachment of compatible suppressors. Ensure proper thread engagement and alignment before use. This is a passive adapter—verify headspace and barrel length compliance with NFA regulations when attaching suppressors.
