PTR Vent Spiritus 556i, 5.56mm, Suppressor

The PTR VENT Spiritus™ 5.56i suppressor represents cutting-edge innovation in firearm sound suppression, crafted specifically for demanding shooters who require reliable performance in compact, lightweight form. Manufactured by PTR Industries using advanced 3D-printed Inconel construction combined with proprietary Purposely Induced Porosity™ (PIP) technology, this suppressor excels in heat dissipation, strength, and reduced back pressure while delivering consistent sound reduction across high-volume firing sessions. Its monolithic design and Diamond-Like Carbon (DLC) finish ensure exceptional durability against wear, corrosion, and extreme thermal stress, making it ideal for tactical, duty, or recreational use on 5.56 platforms.

Measuring a sleek 6 inches in length (without adapter) and 1.625 inches in diameter, the Spiritus™ 5.56i adds minimal weight at just 15.2 ounces (without adapter), preserving rifle balance and handling for short-barreled rifles or full-size builds. Optimized for 5.56x45mm NATO with a minimum barrel length of 10.5 inches, it also supports 5.7x28mm and 4.6x30mm platforms without restrictions, offering broad compatibility. The included 1/2"x28 direct-thread adapter converts to HUB (1-3/8"x24) threading, allowing seamless integration with various quick-detach mounts for enhanced versatility across multiple firearms.

Rated for limited full-auto use with controlled bursts of 120-180 rounds followed by a 10-minute cooldown to ambient temperature, this suppressor prioritizes long-term reliability over theoretical specs. Independent testing, including PEW Science evaluations on MK18 and M4 platforms, confirms its effective suppression, tone quality, and gas management in real-world harsh conditions. Built for shooters who value function, durability, and no-nonsense engineering, the VENT Spiritus™ 5.56i stands out as a premium choice in modern suppressor technology.
