The PTR Industries Vent Spiritus 556 Inconel FDE suppressor is engineered for shooters who want durable, repeatable performance in a compact package. Built from advanced 3D-printed Inconel and finished in flat dark earth Cerakote, it uses PTR’s Purposely Induced Porosity vented design to manage gas, reduce back pressure, and deliver consistent sound reduction while keeping weight to a manageable 15.2 ounces. Measuring 6 inches long with a 1.625-inch diameter, it balances well on modern carbines without feeling front-heavy.

This model is optimized for .223 Remington / 5.56 NATO and is full-auto rated within specified firing schedules, making it suitable for demanding training and high-volume range use. It includes a 1/2x28 direct-thread adapter that interfaces with the 1.375x24 HUB pattern, giving you broad mounting compatibility across hosts and muzzle devices. Whether you’re refining fundamentals on the range or building a refined suppressed rifle setup, the Vent Spiritus showcases PTR’s focus on thoughtful engineering and modern manufacturing.
