Constructed out of 6Al-4V Grade 5 Titanium and CNC welded the lithium was designed from the ground up to offer the best weight to suppression ratio of any 9mm SMG/PCC suppressor on the market.


It uses internal features and venting to help reduce port pop on direct blowback operating systems and features industry standard 1.375×24 (also known as HUB/ASR Bravo) rear mounting threads to easily be adapted to the mounting system of your choice. The lithium 9 is compatible with 3 lug and booster/piston mounts and can be used on 9mm handguns.


Due to its construction and Otter Creek Lab's bulletproof warranty, the Lithium is also rated for use on 5.56/.223, 308/6.5 creedmoor, 350 legend, and other rifle pressure calibers despite weighing it at only 5.7 oz. Despite being one of the lightest weight suppressor options on the entire market, the Lithium 9 is still full auto rated for 9mm and 300 BLK.
