Product Description

Product Description

The VENT Spiritus™ 5.56i is engineered for shooters who run their equipment hard and expect it to hold up. Built from advanced 3D-printed Inconel and utilizing VENT’s proprietary Purposely Induced Porosity™ technology, this suppressor delivers serious strength, heat tolerance, and consistent performance in a compact, lightweight form factor.

Optimized for 5.56×45, the VENT Spiritus™ 5.56i measures just 6 inches long and 1.625 inches in diameter, keeping overall rifle length and handling in check. At only 15.2 ounces (without adapter), it adds minimal front-end weight while maintaining the durability required for high-round-count use. The Diamond-Like Carbon (DLC) finish provides excellent wear resistance and thermal durability, along with a clean, professional appearance.

Designed with versatility in mind, the VENT Spiritus™ 5.56i includes a 1/2”x28 direct-thread adapter to 1-3/8”x24 HUB, making it compatible with a wide range of mounting solutions and platforms. It is rated for limited full-auto firing schedules—120 to 180 rounds fired in controlled bursts—followed by a 10-minute cool-down to ambient temperature, ensuring long-term reliability.

Safety and performance go hand in hand. A minimum barrel length of 10.5 inches is required for 5.56×45, while no minimum barrel length applies for 5.7×28 or 4.6×30 platforms. Built for shooters who prioritize function over hype, the VENT Spiritus™ 5.56i is a no-nonsense suppressor that delivers where it matters most.
