It uses a fully 3D printed Inconel core with a Diamond-Like Carbon exterior and the VENT series PIP metal-foam geometry to cut back pressure while maintaining strong muzzle control. Specs are 6 inches long, 1.625 inches in diameter, and 15.2 ounces without the adapter. The rear is HUB 1.375x24 and the kit includes a 1/2x28 direct thread adapter to get you running on day one. Rated for 5.56 NATO with a minimum 10.5 inch barrel, and also listed for 5.7x28 and 4.6x30 with no barrel minimum. Manufacturer notes a limited full-auto schedule with cooldown as well as simple solvent-soak maintenance for the PIP section. If you want QD, add a HUB adapter for systems like KeyMo, Xeno, or ASR.
