The Energetic Armament Direct Thread Adapter (brand part number EA21) converts a suppressor’s industry-standard 1.375×24 mounting thread down to a 5/8×24 host barrel, letting you run a 1.375×24-threaded suppressor on a smaller host thread without a separate mount kit. Machined from titanium, it keeps the added length and weight at the muzzle to a minimum compared to a steel adapter, which matters most on lighter, maneuverable builds.
