A Rival Arms stainless steel 1/2"-28 thread protector for 9mm keeps your barrel threads safe when a suppressor isn't mounted. If you run a suppressed 9mm pistol or rifle, you know that exposed 1/2"-28 threads are vulnerable to dirt, debris, and corrosion—especially if you're moving between field and range or swapping cans. This protector screws onto your muzzle in seconds and stays put until you're ready to attach your suppressor, preserving thread integrity and protecting the precision fit your can depends on.
Built from 416R stainless steel with a durable black PVD coating, the Rival Arms thread protector resists wear and corrosion while maintaining a clean, low-profile appearance. The straightforward design doesn't add bulk or weight, and it's small enough to keep in a range bag or pack without taking up space. Whether you're a dedicated suppressor shooter or just want insurance against thread damage, this is the kind of inexpensive maintenance accessory that pays for itself the first time it prevents a fouled bore.
Compatible with any 9mm firearm featuring a standard 1/2"-28 muzzle thread—the most common spec for 9mm suppressors and brake adapters—this protector is a no-fuss upgrade for pistol and rifle shooters alike.
| Brand | Rival Arms |
| Material | 416R Stainless Steel |
| Finish | Black PVD |
| Thread Pitch | 1/2"-28 |
| Caliber Compatibility | 9mm |
Yes, provided your firearm has a 1/2"-28 muzzle thread, which is the standard spec for 9mm suppressors and muzzle devices. If you're unsure of your thread pitch, check your owner's manual or the specs of any suppressor or muzzle brake you own.
No. The thread protector is designed for storage and transport when a suppressor or other muzzle device is not mounted. Remove it before firing.
Exposed muzzle threads are prone to fouling, corrosion, and damage that can interfere with the fit of a suppressor or other muzzle device. A protector keeps threads clean and safe when a can isn't attached.
The protector screws onto your muzzle threads; it is not meant to be used simultaneously with a suppressor. When you're ready to mount your suppressor, unscrew the protector and attach the can directly to the threads.
