YHM Hub Direct Thread Mount System M14x1LH Thread

The Yankee Hill Machine Hub Direct Thread Mount System converts any HUB-compatible suppressor into a direct-thread design, letting you swap mounting systems without swapping suppressors. If you've got a HUB suppressor sitting in your safe but prefer the simplicity and rock-solid lockup of direct threading to your barrel, this adapter bridges that gap. The conversion is straightforward: remove the existing mount from your suppressor, thread on the YHM Direct Thread Mount with a 3/4" open end wrench, then thread the whole assembly directly onto an M14x1 left-hand barrel.

Built from 17-4 precipitation-hardened stainless steel and finished in black oxide, this mount won't budge under recoil or vibration. The 1.375"-24 mounting threads mate directly to any M14x1LH barrel, delivering the kind of rigid connection serious shooters demand at the range or in the field. At just 1.7 ounces, the weight penalty is negligible—you're gaining repeatability and simplicity without a noticeable shift in your barrel's balance.

The .45 caliber bore works across a range of suppressor sizes, so you're not locked into one can forever. This is the move if you've invested in a quality HUB suppressor and want the flexibility to run it direct-thread when it suits your rifle setup.

Frequently Asked Questions

Will this work with my HUB suppressor?

Yes. This mount is designed specifically to convert any HUB-compatible suppressor to direct-thread configuration. You'll remove your current HUB mount from the suppressor body and thread this adapter on in its place.

What barrels does the M14x1LH thread fit?

This mount is threaded for M14x1 left-hand barrels. Verify your barrel threads before ordering—left-hand threads are common on certain platforms and calibers but not all.

Do I need any special tools to install this?

You'll need a 3/4" open end wrench to thread the mount onto your suppressor. Installation to the barrel itself depends on whether your suppressor is already HUB-equipped; if so, this adapter simply replaces that existing mount.

What calibers can I use with the .45 bore?

The .45 caliber bore is suitable for .45 ACP and other rimless cartridges within that diameter. It is not appropriate for rifle calibers larger than .45.
