ANGSTADT HUB 1/2X28 DT ADAPTER

The Angstadt HUB 1/2x28 DT adapter is a universal direct-thread mounting solution for suppressors built on the HUB (Hybrid Universal Base) 1.375×24 thread platform. If you run one of these cans and want a low-profile setup without additional mounting hardware, this adapter threads directly onto your rifle's muzzle and mates to your suppressor with minimal footprint. It's the same adapter Angstadt includes with their Reticent suppressors—proven design, clean execution.

Built from 17-4 stainless steel and finished in black nitride, this adapter is made to last through years of shooting. The engineering is straightforward: it converts a 1/2×28 rifle muzzle thread to the HUB threading on your suppressor, keeping profile extension to just 0.2 inches. That matters when you're balancing sight radius, handguard clearance, and overall rig manageability. At 2.5 ounces, it's not adding noticeable weight to the can or the gun.

Whether you're building a precision rig for long-range work or setting up a hunting rifle for reduced report, this adapter gives you the direct-thread benefits Angstadt engineered into the Reticent line without being locked into a single suppressor brand. If your HUB-threaded can needs a 1/2×28 interface, this is a no-frills, American-made solution that works.

Frequently Asked Questions

What suppressors does this adapter work with?

This adapter is designed for suppressors with HUB (Hybrid Universal Base) 1.375×24 threading. It's the same adapter included with Angstadt Reticent suppressors and will work with any other suppressor manufactured to the HUB standard.

What rifle thread does my barrel need?

Your rifle barrel must have 1/2×28 TPI threading. This is the standard muzzle thread on most modern .22 and .223/5.56 rifles. If your barrel is threaded to a different pitch (like 5/8×24 or 9/16×24), you'll need a different adapter.

How much does this add to the length of my suppressor?

The adapter adds just 0.2 inches to the back (rear) of your suppressor, making it one of the slimmest direct-thread solutions available for HUB-threaded cans.

Is this the same as what comes with Angstadt Reticent suppressors?

Yes—it's the same adapter included with Reticent suppressors, but sold separately with a black nitride finish.
