The Otter Creek Labs Lithium 9 is a compact 9mm suppressor built from 6Al-4V Grade 5 titanium with an FDE finish. CNC welded for durability, it measures 6 inches (no mount) and weighs 5.7 ounces (no mount). Internal venting and features are designed to reduce port pop on direct blowback operating systems. The unit accepts industry-standard rear mounting (1.375×24 HUB/ASR Bravo) and includes a 1/2×28 direct thread adapter for immediate use on many 9mm platforms.
Typical applications for the Lithium 9 include use on PCC/SMG-style rifles and on 9mm handguns where reduced weight and standard mounting options are priorities.
