PTR VENT Complete Suppressor Collection

The Complete VENT Suppressor Line

The PTR VENT Complete Suppressor Collection combines the VENT 1, VENT 2, VENT 3, and VENT SPIRITUS™ 5.56i in one package. The collection provides dedicated configurations for .30-caliber rifles, 9mm PCCs and compatible handguns, and two distinct approaches to 5.56 suppression.

Each suppressor can remain configured for its intended host and mounting system, reducing the need to move one suppressor and its mounting hardware between substantially different firearm platforms.

Monolithic 3D-Printed Construction

The VENT 1, VENT 2, and VENT 3 use monolithic structures 3D printed from titanium. This manufacturing process integrates the internal gas-management geometry directly into each suppressor body instead of using a conventional stack of individually assembled baffles. Titanium keeps their weights to 12.3 ounces, 8.9 ounces, and 11.75 ounces, respectively.

The SPIRITUS 5.56i uses the same monolithic manufacturing approach with Inconel instead of titanium. Inconel provides a material platform selected for strength and resistance to the temperatures associated with demanding rifle firing schedules.

PIP Gas-Management Architecture

All four suppressors incorporate PTR’s Purposely Induced Porosity™ technology. The architecture uses engineered porous structures and controlled internal flow paths to manage expanding combustion gases while reducing the pressure accumulation associated with more restrictive suppressor designs.

The SPIRITUS 5.56i adds radial PIP venting as part of its pressure-management system. This is particularly relevant on semiautomatic 5.56 rifles, where suppressor-induced pressure can affect shooter-side gas, ejection-port signature, and weapon behavior.

Two Different 5.56 Configurations

The VENT 3 is the lightweight, full-size 5.56 model in the collection. It measures 7.75 inches, has a 1.625-inch diameter, and weighs 11.75 ounces without its mount. Its titanium construction prioritizes internal volume and lower muzzle weight.

The SPIRITUS 5.56i measures 6 inches and weighs 15.2 ounces without its adapter. Its shorter Inconel body reduces overall length and supports a more demanding firing schedule, trading some of the VENT 3’s weight advantage for increased material durability. The SPIRITUS also adds compatibility with 4.6×30mm.

Mounting Configured for Each Platform

The VENT 1, VENT 3, and SPIRITUS 5.56i use 1-3/8×24 HUB mounting interfaces, allowing them to accept suitable HUB-pattern mounting systems. The VENT 2 uses a 1.125×28 Alpha interface and incorporates a booster cage for use with compatible pistol-mounting components.

Each suppressor includes a direct-thread adapter matched to commonly used barrel threads in its primary caliber class. Alternative mounts, pistons, or boosters must be compatible with the suppressor, host firearm, barrel thread, and operating system.

Why This Collection Exists

This collection provides the complete VENT suppressor range in one package. It covers full-size .30-caliber rifle suppression, lightweight 9mm applications, lightweight full-size 5.56 suppression, and compact Inconel 5.56 suppression for more demanding use.

The inclusion of both the VENT 3 and SPIRITUS 5.56i allows the 5.56 suppressor to be selected according to the host and firing requirements rather than treating the two models as interchangeable configurations.
