The latest in the VENTUM series—the VENTUM 556 brings HUB compatible Flow-Through® technology to dedicated 5.56 weapon systems. With a removeable 3D-printed Grade 5 Titanium core and 17-4 stainless steel suppressor housing, the VENTUM 556 is easily serviceable and provides all the benefits of true Flow-Through® technology including toxic fume mitigation, improved sound performance, and excellent repeatability. Full-auto rated and direct thread ready, this multi-caliber suppressor is versatile with a detachable GeoFlash™ cap and comes ready to accept universal HUB and Stiction mounting systems. The universal HUB mounting system will allow adapters such as Xeno, KeyMo, and ASR, plus other approved mounting systems. It is cross-platform functional and ideal for bolt and lever action, centerfire, submachine gun, bullpup, and AK platforms.

With the Flow-Through® design no significant modifications to the platform or gas system are required to install or operate this suppressor.

Flow-Through® technology cycles and redirects expanding gases in a helical pattern away from the bore-line, through the front of the suppressor, and away from the shooter’s face, eyes, and lungs.

Ships with a 1/2×28 direct thread adapter.
