PRE-ORDER Guidance
As you are probably aware, recent updates to ATF's eForm approval process has resulted in drastically improved turnaround times. While this is certainly a positive change, it has also had a predictable impact on suppressor inventory across the industry.
With that in mind, if you know you want a particular suppressor (or three) and it isn't in stock, your best bet is to place a "PRE-ORDER" so that we can purchase your desired suppressor the moment it becomes available from our distributors. If you wait until it shows in-stock on the website, you might miss your opportunity. PRE-ORDER helps us seek out and purchase what you are looking for. This is true whether you buy from us or someone else.
Thank you for considering Longbow Arms, we hope to earn your business.

Lithium 9 (BLK or FDE)
DESCRIPTION
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.
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.
