1/2x28 to 5/8x24 Thread Adapter – .223/5.56 – Silver
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
This Odin Works thread adapter is made for shooters running a 1/2x28 threaded barrel who need to mount a 5/8x24 muzzle device or suppressor interface. Odin Works builds this one from 416R stainless steel, and it includes a thread protector, which makes it a straightforward solution when your barrel thread and your muzzle setup do not speak the same language.
This is a fitment-sensitive part. Thread pitch matters, caliber matters, and shoulder alignment matters. Buy it right the first time or enjoy the classic hobby of returning parts you should have measured first.
Fitment
- For barrels threaded 1/2x28
- Adapts to 5/8x24 muzzle device / suppressor thread pattern
- Common use case: .223 Remington / 5.56 NATO platforms
Does NOT fit
- Barrels without 1/2x28 muzzle threads
- 5/8x24 muzzle devices that require a different shoulder geometry or platform-specific mount setup
- Do not assume universal suppressor compatibility without confirming your suppressor, mount, and bore clearance requirements
What it does
This adapter converts a 1/2x28 muzzle to 5/8x24 so you can run a larger-threaded muzzle device or suppressor mount on the correct barrel thread. In plain English: it bridges a thread mismatch so your hardware can mount correctly.
Why it’s worth it
It saves you from replacing a barrel or ditching a muzzle device just because the threads do not match. For the right setup, this is a cheap, clean answer. For the wrong setup, it is a fast way to create alignment problems. That is why verification matters here.

Install notes
Verify thread pitch on both the barrel and the muzzle device before installation. Check alignment and clearance carefully, especially if the end use involves suppressor mounting. If there is any doubt, stop guessing and let a qualified gunsmith handle it.
Verify before you buy
Verify your barrel thread is 1/2x28. Verify your muzzle device or suppressor mount is 5/8x24. Verify the bore size and intended caliber setup are appropriate for the adapter and mounted accessory.
