Griffin Armament OPTIMUS 6 6mm Suppressor Utility Mount — Black
The Griffin OPTIMUS 6 6mm Utility Black is Griffin’s 6mm precision suppressor with utility mount interface — the Utility variant offers a different mounting configuration than the Taper Mount version, for flexibility across different host setups. Optimized for 6mm Creedmoor, 6mm ARC, 6mm GT, .243 Win, and compatible 6mm calibers.
Griffin Armament is a Florida-based American suppressor manufacturer known for the Dual-Lok mounting system, the Taper Mount platform, and a broad lineup covering everything from compact pistol suppressors to precision .30 cal rifle cans. Griffin’s OPTIMUS line introduced versatile multi-caliber suppressors, the RECCE line targets maximum suppression for precision shooters, the Sportsman UL brings ultralight options, and the GP (General Purpose) series prioritizes accessibility and value.

Since October 9, 2026 it transfers on a standard Form 4473, with no Form 4 or tax stamp. Current ATF approval times vary — see our NFA wait times guide.

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.
