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 Century Arms EOS-30 Ti is a .30 caliber suppressor with a 3D-printed titanium body and a 5/8×24 direct thread mount. It comes from the EOS line, short for Eye of the Storm, which is built with additive manufacturing instead of the usual machined parts.
What makes it different
This suppressor does not use traditional baffles. The 3D-printed design is meant to keep back pressure low while still cutting sound. The titanium construction keeps weight down to 10.8 oz, and the finish is matte. It also has an integrated flash hider and is HUB compatible, so it works with HUB mounting accessories.
The EOS-30 Ti is optimized for semi-auto .300 BLK. The maker also points to AR platforms and hunting use. A light suppressor like this suits a shooter who carries a rifle for long stretches and does not want extra weight hanging off the muzzle.
To run it, you need a host with a matching 5/8×24 threaded muzzle. That could be a .300 BLK AR build or a .30 caliber hunting rifle threaded to that pitch. If you plan to use HUB accessories, check that your setup is built around the HUB system. Make sure your barrel and muzzle device match the thread before you mount it.

Warranty and Manufacturer
Covered by the Century Arms factory warranty; warranty terms come from Century Arms.
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.
