Rival Arms Thread Protector 9mm Luger 1/2x28 Stainless PVD 416R Stainless Steel

The Rival Arms Thread Protector is a precision-machined accessory designed to safeguard the muzzle threads on your 9mm Luger barrel when a compensator or suppressor is not in use. Cut for the 1/2x28 thread pattern common on 9mm pistol barrels, this protector keeps your muzzle threads clean, shielded from debris, and ready for the next device installation.

Each protector is CNC-machined from 416R stainless steel billet, the same high-grade material Rival Arms uses in its match-grade barrels, delivering exceptional strength and long-term corrosion resistance in a compact, low-profile package. The Stainless PVD finish further enhances surface durability and gives the protector a clean, refined look that pairs naturally with both stainless and black-nitride barrels.

Whether you run a dedicated suppressor host, a compensated carry pistol, or simply want to keep a fresh barrel's threads protected during transport and storage, the Rival Arms 9mm Thread Protector offers a precision fit, simple installation, and years of dependable service.
