PTR VENT Spiritus 5.56i Suppressor *Class 3 NFA Item*

The VENT Spiritus 5.56i is a premium, 3D-printed sound suppressor engineered to deliver an ideal balance of lightweight handling and extreme durability. Designed for shooters who push their gear hard, the Spiritus 5.56i is built to endure sustained use without sacrificing performance. Manufactured from advanced 3D-printed Inconel and enhanced by VENT’s proprietary Purposely Induced Porosity technology, this suppressor offers exceptional strength, heat resistance, and repeatable performance in a compact footprint. The result is a rugged, mission-ready suppressor that excels under demanding conditions. Optimized for 5.56×45, the Spiritus 5.56i measures just 6 inches in length with a 1.625-inch diameter, preserving rifle balance and maneuverability.

Weighing only 15.2 ounces (without adapter), it minimizes front-end weight while remaining robust enough for high round counts. A Diamond-Like Carbon (DLC) finish enhances wear resistance, thermal durability, and delivers a clean, professional aesthetic. Versatility is built in, the Spiritus 5.56i ships with a 1/2×28 direct-thread adapter to 1-3/8×24 HUB, ensuring compatibility across a wide range of mounting systems and host platforms. It is rated for limited full-auto use, supporting 120–180 rounds in controlled bursts, followed by a 10-minute cool-down to maintain long-term reliability. Designed with safety and performance in mind, the suppressor requires a minimum 10.5-inch barrel for 5.56×45, while no minimum barrel length is required for 5.7×28 or 4.6×30. Built for shooters who value proven engineering over marketing hype, the VENT Spiritus 5.56i delivers dependable performance where it matters most.
