Silencerco HARVESTER BIG BORE THREAD MOUNT M18 X 1.5

The SilencerCo Harvester Big Bore thread mount in M18 x 1.5 is a modular adapter that lets you attach your Harvester Big Bore suppressor to rifle barrels threaded to this specific pitch. SilencerCo designed these interchangeable thread mounts to expand the versatility of their big bore suppressor platform, so you're not locked into one barrel setup. If you're running a precision rifle, hunting rifle, or other firearm with an M18 x 1.5 muzzle thread, this mount makes it simple to install and remove your suppressor as needed.

These thread adapters are sold individually, which means you can stock multiple mounts if you have several barrels or rifles in the same thread pitch. That way, each gun can have its own adapter permanently installed and ready to go. It's a practical approach that saves you from constantly switching the same mount between firearms and eliminates the hassle of tracking parts.

Fit and function are critical with suppressor mounting, so verify that your barrel is indeed threaded M18 x 1.5 before ordering. Many modern European and some precision rifle manufacturers use this thread pitch, but it's always worth confirming with your gunsmith or barrel specs to avoid compatibility issues. Once you've confirmed the thread pitch matches, installation is straightforward.

Frequently Asked Questions

Will this thread mount work on my rifle barrel?

Only if your barrel is threaded M18 x 1.5. Double-check your barrel's thread pitch and diameter before purchasing. This adapter is designed specifically for that pitch and won't fit other thread sizes.

Do I need multiple thread mounts if I have several rifles?

You can use one mount on different rifles by unscrewing and reinstalling it, but purchasing individual adapters for each gun lets you leave each mount permanently threaded to its barrel—much more convenient if you regularly swap your suppressor between firearms.

Is this mount included with the Harvester Big Bore suppressor?

No, thread mounts are sold separately. The suppressor itself comes with its own quick-detach system, but additional thread adapters in different pitches allow you to attach it to various barrel configurations.

Can I use this with suppressors other than the Harvester Big Bore?

No. This thread mount is specifically designed for the SilencerCo Harvester Big Bore suppressor. Using it with other suppressors may result in improper fit or unsafe operation.
