The VENT Spiritus 5.56i suppressor is built for hard-use shooters who demand durability, heat resistance, and consistent performance in a compact design. Constructed from advanced 3D-printed Inconel and using VENT's Purposely Induced Porosity technology, it delivers strong gas control, reduced back pressure, and reliable suppression in a lightweight form factor. Optimized for 5.56X45, it measures 6 inches long and 1.625 inches in diameter, helping maintain balanced handling while adding only 15.2 ounces without the adapter. The suppressor includes a 1/2X28 direct-thread adapter to 1.375X24 HUB for broad mounting compatibility and is rated for limited full-auto use of 120 to 180 rounds in controlled bursts followed by a 10-minute cool-down. It requires a minimum 10.5-inch barrel for 5.56X45, while also supporting 5.7X28 and 4.6X30 platforms without barrel restrictions, making it a versatile, performance-focused suppressor designed for demanding use.
