The PTR Vent Spiritus 5.56i Suppressor delivers exceptional performance for 5.56 NATO platforms, combining innovative materials with cutting-edge design. Engineered with 3D-printed Inconel and proprietary Purposely Induced Porosity™, the Vent Spiritus offers superior strength, heat resistance, and sound suppression in a compact package. Built for professionals and enthusiasts who demand reliability under the most challenging conditions, this suppressor enhances accuracy and shooting comfort without adding excessive weight.
Featuring advanced 3D-printed Inconel construction, the PTR Vent Spiritus 5.56i represents the next evolution in suppressor technology, ensuring optimal performance across tactical and recreational applications.
The feature set of the original Vent series, now in Inconel!
The PTR Vent Spiritus 5.56i is engineered for those who refuse to compromise on performance. Its Inconel construction provides exceptional durability and heat management capabilities, critical for maintaining consistent performance during extended use. The suppressor's lightweight profile minimizes shooter fatigue during transport and operation, a crucial consideration for both professional and recreational applications.
The Vent Spiritus features advanced thermal management that allows for sustained fire capability with appropriate cooling periods, ensuring reliable functionality even under demanding conditions. With HUB compatibility (1.375x24 female threading), this suppressor accepts various industry-standard mounts and adapters, including the included 1/2x28 direct thread adapter that fits most AR-15 and 5.56 NATO firearms.
Designed for effective sound reduction, the Vent Spiritus significantly decreases the acoustic signature of your firearm, enhancing shooting comfort and reducing environmental impact without sacrificing performance.
The innovative PIP (Purposely Induced Porosity™) technology in the PTR Vent Spiritus 5.56i represents the cutting edge of suppressor design. During the 3D printing process, precisely engineered microscopic void structures are created throughout the suppressor body. These carefully calculated patterns of porosity create optimized flow paths that efficiently manage expanding gases while providing additional surface area for superior heat dissipation. Specifically calibrated for 5.56 NATO ammunition, this technology delivers exceptional sound reduction while allowing shooters to maintain tactical awareness.
The HUB threading system (1.375x24) provides compatibility with numerous mounting solutions, allowing users to configure their setup according to specific needs and preferences. The included 1/2x28 direct thread adapter ensures out-of-the-box compatibility with standard 5.56 NATO barrels. This versatility makes the Vent Spiritus an ideal choice for shooters who demand adaptability alongside premium performance.
Based on the lab report from PEW Science, here's what you should know about the PTR VENT Spiritus 556i suppressor in 5.56mm:
In summary, the VENT Spiritus 556i represents a significant technological advancement in suppressor design, especially for its size. It performs exceptionally well on both short and long barrels, with notably better performance on the longer barrel configuration. Its unique PIP technology allows it to achieve sound reduction levels that were previously only possible with larger or specialized flow-through designs.
In Pew Science Testing, the VENT Spiritus 556i has performance characteristics very similar to the HUXWRX Flow 762 Ti and the CAT ODB 718, while exceeding the performance of the Rugged Razor 762, the Dead Air Sandman S and the Dominos SR from Thunder Beast. So, quite impressive.

Buying and shipping through Charlie’s is easy, but there is some information you need to know. This item must ship to FFL holder. No civilian exceptions.
1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state.
2) Find your FFL… Have your dealer send us a copy of their FFL and SOT to Charlie’s (Make them earn their fee!). Not every FFL is a SOT or Class 2 / Class 3 dealer.
3) Be patient! You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.
That’s it! We try to make this process as simple as possible for our customers. Please click the “Buying a Firearm” tab at the top of this page for more information.
THIS IS A SERIALIZED ITEM. It must ship to a Federal Firearms License holder. No civilian exceptions.
Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:
1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.
2) A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.
3) After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).
4) Have your dealer send us a copy of their FFL to FFL@CharliesCustomClones.com. Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)
5) Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.
That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Suppressor page for more details.
