Energetic Armament EA21 Direct Thread Adapter 5/8x24 Titanium

The Energetic Armament EA21 Direct Thread Adapter lets a shooter mount any suppressor built around the industry-standard 1.375"x24 hub directly to a rifle barrel threaded 5/8x24, eliminating the need for a quick-detach mount or muzzle brake interface. It is precision-machined from US-origin, DFARS-compliant 6AL-4V titanium and coated in a black Cerakote finish for corrosion resistance and glare reduction. Spanner slots on the adapter body allow easy installation and removal with a standard spanner wrench.

Sized for 30 caliber and similar rifle platforms, the EA21 is purpose-built to mate the Energetic Armament VOX family and any other hub-compatible suppressor to a 5/8x24 muzzle. The titanium construction keeps added weight to a minimum while delivering the strength needed for sustained fire, and the low-profile design keeps the overall rifle length manageable. Made in the USA.
