The Otter Creek Labs Lithium 9 is a light, all-titanium 9mm suppressor. At just 5.7 oz it barely changes how your pistol or PCC handles, and it ships ready to direct-thread onto 1/2x28 barrels. A 1.375x24 HUB rear thread lets you switch to a 3-lug, booster or quick-detach mount later. This is the Flat Dark Earth Cerakote version.
It is CNC welded from 6Al-4V grade 5 titanium, and internal venting takes the edge off port pop on direct-blowback carbines. Beyond 9mm it is rated for subsonic 300 BLK on full auto, supersonic 300 BLK on 7-inch and longer barrels, and light-duty use on 350 Legend, 5.56 and even 308 bolt guns with a direct-thread mount. Made in London, Kentucky, with a lifetime warranty.
