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 1.375x24 HUB pattern (also called Bravo/ASR), providing compatibility with mounts from Dead Air, SilencerCo, Griffin Armament, Q, and others. The Lithium ships with a 1/2x28 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.

ULTRALIGHT PCC SUPPRESSION
The Otter Creek Lab's Lithium is a lightweight titanium silencer optimized for use on pistol-caliber carbines and subguns. At only 5.7 ounces, it's one of the lightest suppressors on the market and offers the best weight-to-suppression ratio available. It's a traditional 1.5" in diameter, and on the shorter side at just 6" in length. Internal features and venting in the suppressor allow for reduced blowback and port-pop when used on semiautomatic firearms, translating to a much more pleasant experience for the shooter.
A 1.375x24 (HUB/Bravo/Omega pattern) is used in the rear portion for mounting solutions. This allows for countless mounting solutions and combinations. While it ships with a 1/x28 direct thread mount, nearly a dozen quick disconnect solutions are available for multiple manufacturers. Additionally, it can be utilized with a 3-lug mount for PCCs, or booster assembly for traditional pistols.
In addition to 9mm, the Lithium is also rated for numerous other calibers such as 350 Legend, 5.56, and .308.
