SilencerCo Octane Fixed Thread Mount Adapter (Metric 13.5×1 LH)

Description

If you want to use your SilencerCo Octane or Omega suppressor on a firearm with a fixed barrel, this is the factory-original adapter. It replaces the standard piston, spring, and retainer, converting your suppressor to direct thread mounting. This is a popular option for those wanting to quiet down a pistol caliber carbine, or a fixed barrel pistol.

What This Adapter Does

This adapter allows you to use your Octane 9, Octane 45, or Omega 9K suppressor on a firearm with a Metric 13.5×1 Left Hand thread. This is a common thread pattern on many modern pistol caliber carbines, and it’s a straightforward way to add suppression without the need for a dedicated suppressor host.

Oregon Use Cases

Here in Oregon, this adapter opens up a lot of possibilities. For hunters running pistol caliber carbines, it provides a quieter shooting experience in the field. It’s also a solid addition for concealed carry permit holders who want to reduce report when practicing at the range. Home defense benefits from the reduced sound signature, and of course, it just makes range days more enjoyable. The suppressor combined with this adapter allows for improved communication in a hunting camp, or when shooting with a partner.

Important Considerations

Using suppressors requires compliance with all federal, state, and local laws. This adapter is part of a regulated item and requires proper NFA paperwork. Oregon Arms & Ammunition can assist with questions about compliance, but the responsibility for lawful ownership rests with the purchaser.
