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 1.375x24 (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.

Barrel Length / Firing Schedule

• 9mm: Full auto rated, no barrel length restrictions.
• 300 blackout subsonic: Full auto rated, no barrel length restrictions.
• 300 blackout supersonic: Semi auto, 7 inch barrels and longer.
• 357 magnum lever action rifles: Yes, 4 inch barrel length restriction.
• 350 legend, 300 HAMR: Semi auto, 16 inch barrels and longer
• 223/5.56: Semi auto with intent to keep temperature down/low volume use, barrel must be 16 inches or longer.
• 308 Winchester/6.5 Creedmoor: Bolt action hunting applications only/low volume use, 20 inch barrel or longer.

Because the Lithim has a smaller blast chamber than most typical rifle suppressors a direct thread mount must be used if it’s being fired on 350 legend, 300 HAMR, 223/5.56, 308 and 6.5 Creedmoor and other similar cartridges so that you have maximum blast chamber volume not being occupied by a muzzle device.
