Description
OTTER CREEK LABS LITHIUM
The Otter Creek Labs Lithium is a titanium suppressor designed for pistol-caliber carbines and subguns. At 5.7 ounces without a mount, it’s among the lightest 9mm suppressors available. The suppressor measures 6″ in length and 1.5″ in diameter.
Built from CNC-welded 6Al-4V Grade 5 Titanium in a tubeless design, the Lithium uses internal venting to reduce blowback and port pop on direct blowback platforms like the MP5 and Stribog. PEW Science testing on the HK SP5 with subsonic 9mm achieved a composite Suppression Rating of 55.4.
The rear threads use the 1.375×24 HUB pattern (also called Bravo/ASR), providing compatibility with mounts from Dead Air, SilencerCo, Griffin Armament, Q, and others. The Lithium ships with a 1/2×28 titanium direct thread mount but can be configured with 3-lug mounts for PCCs or booster assemblies for pistol use.
Beyond 9mm, the Lithium is rated for rifle calibers including 350 Legend, 5.56, and .308 with barrel length and firing schedule restrictions. A direct thread mount is required for rifle caliber use to maximize blast chamber volume.
