Odin Precision 1/2x28 to 5/8x24 Thread Adapter for Firearm Accessories

If you've got a 1/2x28 threaded barrel but want to run a suppressor or muzzle device with 5/8x24 threads, the Odin Precision 1/2x28 to 5/8x24 Thread Adapter solves that compatibility gap without forcing a new barrel. Built from 416R stainless steel, this adapter is machined to tight tolerances—meaning it'll headspace reliably and stay put through countless rounds. It's a straightforward solution for shooters who already have quality 5/8x24 suppressors or brakes sitting in the safe and need to use them on a 1/2x28 platform.

The adapter comes with a thread protector, so your threads stay clean and protected when the muzzle device isn't mounted. The knurled design gives you solid grip when hand-tightening or removing it in the field. Whether you're a suppressor enthusiast with multiple hosts or just bridging a gap between barrel threads and existing gear, this is the kind of no-BS solution that keeps your setup running.

Odin Works knows precision tooling—this adapter reflects that attention. It's the kind of small, overlooked part that can make or break a build if it's made cheap, so the stainless steel construction and machining quality here are worth the reliability.

Frequently Asked Questions

Can I use a 5/8x24 suppressor on a 1/2x28 barrel with this adapter?

Yes. This adapter threads onto your 1/2x28 barrel and converts it to 5/8x24, allowing you to attach any suppressor or muzzle device with 5/8x24 threads.

What calibers can I use this adapter on?

The adapter itself is caliber-agnostic—it's purely a thread conversion tool. Your barrel's caliber and the suppressor's rating determine what you can shoot through it.

Is the thread protector included?

Yes, the adapter comes with a thread protector to keep the threads clean when a muzzle device isn't mounted.

What's the material and why does it matter?

It's machined from 416R stainless steel, a premium alloy that resists corrosion and maintains tight tolerances through repeated use and thermal cycling—essential for a part that threads directly onto your barrel.
