Yankee Hill 218924 HUB Direct Thread Mount 5/8"-24 tpi 17-4 Stainless Steel Black Melonite QPQ
Yankee Hill Machine
The Yankee Hill Universal Rifle 1/2"-36 TPI suppressor mount is a straightforward adapter that lets you attach an existing suppressor to your rifle without changing your current suppressor. If you've invested in a quality can but switched to a new rifle with different barrel threading, this mount bridges that gap—no need to buy a whole new suppressor or pay for rethreading. The design is dead simple: remove your suppressor's factory mount, thread this adapter onto it, and screw the two-piece assembly directly onto your 1/2"-36 TPI rifle barrel.
Built from 17-4 stainless steel and finished with Melonite QPQ hardening, this mount handles the abuse. The straightforward install means you can't really get it wrong, and it comes off just as easily when you need to swap gear. Since it uses your barrel's existing threading as the mounting interface, there's no extra hardware floating around—just thread it on hand-tight or with a 3/4" open-end wrench if you want it snug, and you're done. This is the kind of solution that makes sense if you're building a versatile rifle setup or consolidating suppressors across multiple hosts.
Yankee Hill Machine has been making no-frills suppressor accessories for shooters who value function over marketing. This mount reflects that philosophy: it does one job cleanly, fits standard 1/2"-36 TPI rifle barrels, and doesn't overcomplicate what should be simple. If your suppressor runs a 1-3/8-24 internal thread, this adapter will let you use it on any rifle you own with that barrel pitch.

This mount is designed for suppressors with a 1-3/8-24 internal thread. If your can accepts that thread pitch, you can adapt it to any 1/2"-36 TPI barrel by removing its original mount and installing this one.
The 1/2"-36 TPI standard is common on many modern rifles, but you'll need to verify your barrel's specific threading before ordering. Check your rifle's documentation or have it measured at a gunsmith if you're unsure.
No. Remove your suppressor's existing mount, thread this adapter onto it (using a 3/4" wrench if needed), then screw the two-piece suppressor assembly onto your barrel. The simple design makes cross-threading virtually impossible.
Yes. Simply unscrew the mount from your suppressor and thread it back onto the original suppressor mount, or install a different mount if you're moving it to another host.
