Engineered for professionals and demanding shooters, the PTR VENT 3 Suppressor brings cutting-edge suppression technology to the 5.56x45mm platform. Its standout feature-Purposely Induced Porosity(TM) (PIP(TM))-uses a precisely tuned, 3D-printed titanium structure to optimize gas flow, reduce back pressure, and manage heat far more efficiently than traditional baffle stacks. The result is a lighter, stronger, and noticeably quieter suppressor built to perform in any environment. The monolithic printed body increases rigidity and thermal resistance, while the advanced internal geometry controls expansion for consistent, repeatable suppression. Full-auto capable and equipped with a 1/2x28 direct-thread adapter, the VENT 3 is ready for hard use on duty carbines, training rifles, and modern sporting platforms. Its proprietary coatings enhance corrosion resistance and durability, ensuring long service life for shooters who demand top-tier performance.
