Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
The PTR Industries Vent 3 is a titanium suppressor for .223 Remington/5.56 NATO that weighs 11.75 oz. It is 7.75″ long and 1.625″ in diameter, and it wears a Flat Dark Earth Cerakote finish.
What sets the Vent 3 apart
PTR makes the body and core as one 3D-printed titanium piece. The design uses what PTR calls Purposely Induced Porosity, which gives the suppressor a vented layout. PTR says this approach helps with durability, heat dissipation and back pressure reduction. The Vent 3 is also full-auto rated, so it is built for long firing sessions. PTR backs the design with multiple U.S. patents.
This suppressor suits shooters who run 5.56 rifles and want a lightweight can that can take hard use. It mounts by direct thread at 1/2×28, and it is HUB compatible for owners who use that mounting system.
To run it, you need a host with a 1/2×28 threaded muzzle. Most people pair it with a 5.56 rifle or pistol, a HUB compatible mount if they want one, and quality .223 Remington or 5.56 NATO ammunition. A suppressor cover is a common add-on for anyone who wants to manage heat on the outside of the can.
1/2X28 Direct Thread Adapter (per the manufacturer’s listing).

Buying a suppressor now: a Form 4473 and a background check. No Form 4.
Since October 9, 2026, ATF no longer requires a Form 4, tax stamp, fingerprints, photos or registration to buy a suppressor. It transfers like any other firearm: you fill out a Form 4473, pass a NICS background check, and it is yours. No months-long wait.
Texas buyers: suppressors are legal under Texas law. Western Sport has been an SOT / Class III dealer since 2007.
Outside Texas: we ship to an SOT dealer in your state, who completes the 4473 with you. Your state’s law still decides — some states ban suppressors, and some only allow ones registered with ATF.
Want it registered anyway? ATF still accepts a voluntary Form 4. Ask us.
