Rival Arms Fluted Thread Protector 9mm 1/2"-28 Stainless Steel

A fluted thread protector for 9mm handguns with 1/2"-28 threading, the Rival Arms Fluted Thread Protector is built from 416R stainless steel with a PVD finish—a solid choice if you need to preserve your barrel's factory threads without a suppressor. Whether you're protecting threads on a pistol you plan to run unsuppressed long-term or keeping a taper clean between shooting sessions, this protector handles the job without fuss. The fluted design adds visual interest while you're at it.

Rival Arms designs and manufactures their components with an eye toward quality and durability. This thread protector is no exception: stainless steel resists corrosion, and the PVD coating adds a hard, durable layer that stands up to handling and the elements. Installation is straightforward—just hand-tight or a light wrench turn onto your 1/2"-28 threads.

Use this when you're rotating barrels, storing a pistol long-term, or simply need a protective cap that doesn't rattle loose. It's a no-nonsense part that does one thing well.

Frequently Asked Questions

What thread pitch do I need for my 9mm barrel?

This protector is designed for 1/2"-28 threads, the standard on most 9mm Luger pistol barrels. Check your barrel specs before ordering to confirm compatibility.

Will this work with a suppressor-ready barrel?

Yes. A thread protector fits over the same 1/2"-28 threads that a suppressor would use, so it's ideal for protecting threads on suppressor-ready barrels when you're shooting unsuppressed.

Is this protector removable?

Yes, it screws on and off, so you can remove it whenever you need to attach a suppressor or swap barrels.
