Ruger-57 Threaded Barrel Kit 5.4

The Ruger-57 Threaded Barrel Kit 5.4 is a genuine factory accessory designed for operators and precision shooters who require modularity and suppressor-ready capability. This threaded barrel replacement enhances the Ruger 5.7x28mm platform, allowing for the attachment of sound suppressors, muzzle devices, and compensators—essential upgrades for tactical training and professional shooting environments.

Built to factory specifications, this kit ensures the reliability needed for duty-grade applications. The 5.4-inch threaded barrel maintains the 1/2x28 thread pitch standard across the 5.7x28mm platform, facilitating seamless integration with aftermarket suppressors and muzzle devices. Constructed from hardened steel with a professional-grade finish, the barrel is resistant to fouling and corrosion, even during sustained fire and suppressed operations.

The 5.4-inch configuration strikes a balance between velocity retention and compact ergonomics, making it ideal for vehicle carry and close-quarters drills.
