Otter Creek Labs Lithium 9mm SMG Suppressor - Black

Dominate the pistol-caliber carbine and submachine gun class with the Otter Creek Labs (OCL) Lithium 9MM SMG Suppressor. Purpose-built for full-auto or semi-automatic fire, the Lithium 9 delivers one of the best weight-to-suppression ratios on the market today. Engineered specifically to tackle the high blowback and port pop associated with direct blowback operating systems, this compact suppressor provides exceptional sound reduction, reduced backpressure, and a deep, comfortable shooting tone across range sessions and tactical applications.

Precision CNC-welded from 6Al-4V Grade 5 Titanium, the Lithium features a tubeless construction that weighs a featherweight 5.7 ounces (without mount) while measuring a compact 6.0 inches in length. Its rear features industry-standard 1.375x24 HUB threads, allowing effortless pairing with 3-lug mounts, pistol boosters/pistons, or popular QD systems, and ships standard with a 1/2x28 direct thread adapter. Full-auto rated for 9mm and .300 Blackout subsonic with multi-caliber versatility up to .308 Winchester, the Lithium 9 is a well-rounded, heavy-hitting silencer built to perform on any host.
